The Stäubli product assortment is a comprehensive portfolio of articles for measuring equipment. It includes cables, connectors, probes and accessories, manufactured to global norms and in compliance with a range of international standards. These components are characterised highest manufacturing quality, and are primarily designed for professional applications, i.e. in laboratories, industrial/manufacturing plants, for electrical technicians, installers and maintenance staff.
The Stäubli assortment available in the TME catalogue comprises thousands of products. See below for an overview of this assortment, in which the most relevant product groups are highlighted. These include ready-made components, such as oscilloscope probes, as well as components for customised solution designing (e.g. inspection points or test leads) and measuring equipment manufacturing. Regardless of a field of operation, Stäubli guarantees the highest quality of workmanship, durability and availability of products in a broad spectrum of versions, diversified in terms of sizes, installation methods and colours.
Test leads
Cables manufactured by the Stäubli company are designed for most measuring and testing applications – the TME product catalogue features both flexible small-diameter cables and products for high-voltage applications. Depending on the target application and anticipated operating conditions, customers can choose between articles made from a variety of materials – from affordable single-core PVC cables to professional silicone-insulated coaxial cabling.
PVC-insulated cables
Stäubli PVC-sheathed leads are designed as universal cabling available at an optimum quality-to-price ratio, and primarily intended for measurement and test equipment. Their material properties guarantee long service life and UV resistance (which varies, depending on the insulation colour), and all of them come with cores made in the form of copper stranded wires. Their breaking strength is approx. 15 N/mm2.
This product group includes several product series manufactured by this supplier. FlexiVolt-E is a range of lightweight cables for internal connections in mobile devices not subjected to excessive overloads, i.e. laboratory measuring instruments. The FlexiVolt-1V and FlexiVolt-2V solutions are used to design connections with movable instrument elements, e.g. measuring probe leads. They are highly flexible, which facilitates convenient manipulation of connected instrument elements. 2V variants come with double insulation, i.e. a coloured outer layer and white internal sheath (facilitating detection of protective layer damage). FlexiStorm products demonstrate similar mechanical properties, however, they are rated for higher current strength, which is often required for earthing and power supply connections in laboratory applications.

TPE-coated cables
60.7190-20
TPE is a material providing better thermal properties of cables.
Stäubli cables with TPE (thermoplastic elastomer) sheaths offer several desirable properties, e.g. relatively low weight (low density), high resistance of their smooth-to-touch, inextensible, but still flexible insulation and environmentally-friendly, chlorine-free chemical composition. Additionally, this elastomer is resistant to UV radiation, weather conditions and exposure to ozone (often used for disinfection purposes). Furthermore, it retains its mechanical properties in low temperatures. Such features ensure that FlexiPlast-E, FlexiPlast-1V and FlexiPlast-2V cables, whose core design is similar to the abovementioned PVC-coated cables, demonstrate better thermal tolerance (from -30°C to 90°C) and better dielectric parameters.
Silicone-sheathed cables
Cables coated with an external silicone sheath are one of the most durable products in their category. It results mostly from the fact that silicone demonstrates outstanding resistance to thermal factors. Silicone-sheathed cables by Stäubli operate in a temperature range from -50°C to 150°C (e.g. in hot steam conditions). In addition, they are rated for use in temperatures up to 250°C (for a period of several hours) and are able to withstand a temporary contact with elements with temperatures reaching 300°C (e.g. soldering iron tips). Other features of silicone insulation include cable protection against stretching, breaking and impact. Such characteristics as chemical stability of silicone and absence of halogen compounds makes this cabling suitable for field applications, in very harsh weather conditions. Most importantly, if cables are burnt, insulation residues still demonstrate insulating properties.
61.7532-23
Silicone-insulated cables are most durable solutions offered by Stäubli.
Similarly to TPE-insulated cables, the Stäubli silicone-coated cabling portfolio is divided in line with its application areas, and a similar naming convention is retained. Therefore, Silivolt-1V and Silivolt-2V cables are designed mostly for testing and measuring instruments, and SiliStrom cables are designed for earthing and high-current (even up to 245 A) applications.
RG58 coaxial cables
SILI-SC0.5/1.0R
Braided shielding ensures that these cables are highly flexible.
RG58 series coaxial cables are protected by silicone insulation. It makes them suitable for operation in temperatures from -50°C to 90°C. They are also distinguished by high flexibility exceptional for this product class. Impedance of this cabling series is 45Ω, with resistance to voltage of up to 1 kV. Combined with an outside diameter of 4.9 mm, this makes the RG58 series an ideal solution for creating testing and measuring connections in laboratory and industrial settings, as well as for mobile devices that are ultimately intended for field applications (e.g. portable oscilloscopes, reflectometers, etc.).
Cables for high-voltage applications
The FlexiVolt and Silivolt series come in variants labelled as “HV”, i.e. High Voltage. Their core cross-sections range from 0.5 mm2 to 6 mm2, with maximum operating voltage from 5 kV to 30 kV, depending on the diameter. This performance is possible thanks to a core made in the form of an OFC stranded wire, i.e. composed of tightly twisted, very fine copper wire fibres. This design, combined with a thick insulation layer, enables HV cables to be used in high-voltage applications, e.g. measurements in the power engineering and industrial automation sectors or welding equipment testing, etc. Simultaneously, they maintain Class 6 flexibility, which directly translates into comfort of use and ease of storage/transportation.
SILI-HV/0.50-R
A core in a form of a dense, tightly twisted stranded wire is labelled as OFC.
Test leads with pre-installed connectors
During the typical use of measuring equipment, such as repair and servicing work, prototype construction or laying/maintaining installations, it is often necessary to extend cables and create temporary connections or use different probes. Therefore, the quality of the cabling used with various instruments plays a key role: a prerequisite for obtaining correct results is the use of durable cables equipped with pins ensuring reliably repeatable lowest possible resistance. Stäubli test leads with factory-installed connectors are manufactured with such applications in mind, i.e. making multiple and diverse connections under long-term use conditions. This manufacturer also supplies probes and other measuring accessories boasting the same high quality.
One must also note that numerous Stäubli products meet requirements applicable to measuring accessories as per the EN61010 standard. In line with this standard, they are qualified as Category IV, III and II products and can therefore be used when working with mains sockets or testing electric system switchgear, high-voltage fuses and even power lines.
Banana test leads
Testing and measuring instruments, as well as laboratory power supplies, most commonly use banana test leads whose typical diameters are 2 mm or 4 mm. Instruments, probes and other measuring tips come with female sockets. Universal cables with male plugs can therefore serve a variety of functions – whether for testing, power supply or earthing of selected circuit points.
SLK425-E/N-02523
Professional leads ensure both measurement precision and operation comfort.
Stäubli test leads with pre-installed banana connectors are available in length versions up to 2 m, withstanding even 5 kV voltage. They are available in various colour versions, which facilitates identification of individual leads. The assortment includes axial or angular (contact set at 90° in relation to the cable axis) sockets. A pin is usually housed in a sleeve, which improves connector attachment in a socket, and also ensures safety of use (e.g. by making it difficult to accidentally touch the contact shorted to a power line). Selected products come with female connectors facilitating making serial connections. Serial connections are also possible with leads equipped both with a pin and an integrated socket. Such elements are indispensable for frequent measurements on points located at a considerable distance (e.g. testing electric system sections) or requiring complex connections (e.g. motor stators). The TME product catalogue contains special-purpose variants, e.g. XDK-KELVIN cables with 2-channel crocodile clips. Two such accessories are used to perform measurements employing the Kelvin method (accurate determination of resistance of an object in which the impact of wire resistance on the test result is minimised).
Stäubli also supplies small-diameter cables with 2 mm connectors used in digital signal analyses, small electronic component servicing/prototyping, etc.
BNC cables
BNC connectors are commonly used in numerous cutting-edge laboratory devices, mostly oscilloscopes. These are easy-to-handle coaxial connectors (shielding a measurement line), with very low resistance, yet protected against accidental disconnection. Stäubli offers cables with BNC connectors in several female-female and male-female versions and colours, i.e. black, red, blue and grey; with length ranging from 0.5 m to 2 m. They demonstrate typical impedance (45Ω or 50Ω), which makes them compatible with lab applications. This Stäubli product group also features handy accessories, e.g. BNC standard/4 mm banana plug adapters.
XLAM-446/SC-100
Adapters equipped with 4 mm and BNC connectors are an example of numerous, extremely practical Stäubli accessories.
Connector contacts are made of nickel-plated brass and the insulation is made of PVC or silicone, which makes these cables flexible and relatively lightweight, ensuring comfortable handling. Selected products can be used for measurements in electric systems (300 V and 600 V), since they belong to Category II and III as per EN61010.
Cables with test probes
XPF-484-10021
Typical, black, “negative” probe compatible with most multimeters.
Users looking for basic test leads, such as multimeter accessories, often go for cables that are factory-fitted with probes. Indeed, this often proves to be the most convenient solution, especially for field technicians.
Stäubli leads fitted with probes come with insulated banana plugs, which is a standard solution for high-quality multimeters. Most probes are equipped with caps exposing only the end of a measuring tip, which facilitates handling compact circuits and multi-core cables. It is worth noting that probes are compatible with 4 mm diameter banana sockets. When caps are removed, they can be placed in a connector and perform a variety of functions, not necessarily as measuring tips.

This group of products also includes normally-open bridges, with or without a terminal, as well as a range of special-purpose plugs for high-voltage applications, deep sockets (up to 71 mm) and 2 mm/4 mm format adapters.
Banana sockets
SLB4-E-20
A clearly labelled earthing socket for insulated banana plugs.
Banana sockets are used not only for construction of measuring equipment, but also for control panels (where they streamline instrument maintenance and diagnostics), for workplace arrangement purposes (e.g. providing convenient access to power supply lines), as spare parts and many other applications – whether in laboratories, industry, medicine or electronic service centres. Most Stäubli products belonging to this group are panel-mounted. These are 1.5 – 4 mm connectors with a threaded body and a cable terminal or for a direct connection with a PCB circuit. Similarly to the abovementioned terminals, they come in a range of colours and their contacts are nickel-plated or gold-plated, making them resistant to corrosive agents and guaranteeing a solid connection even under continuous operation conditions. A special type of banana connectors is a socket strip combining several dozen terminals in a single body.
BNC panel-mounted connectors
BNC panel-mounted connectors are useful in similar applications. As they are made to Category II and III standards, they can be used in industrial applications, transmitter and relay stations, but especially in measuring instruments. They come in soldered, screwed and crimped variants, which facilitates selection of a product to suit the preferred method of connection; the manufacturer also provides a range of connectors with pre-installed cabling. A special type of BNC socket is model intended for THT mounting directly within a PCB circuit – these models are targeted primarily at electronic equipment manufacturers, which also includes small-volume production.
Miscellaneous connectors, adapters and accessories
The Stäubli product portfolio also includes numerous minor accessories useful in the field of electric and electronic measurements. These include, for example, items intended to help organise work, such as connector markers and coloured clips slid onto cables; test lead hangers, i.e. indispensable pieces of equipment for lab workstations; 4 mm connectors with a core in the form of a wire to create permanent terminals at installation points where regular measurements are conducted.
