Vishay Intertechnology, Inc. today introduced two new panel potentiometers featuring integrated knobs and IP67 sealing. Offering a high dielectric strength of 5000 VAC and power ratings up to 1 W at +40 °C, the Vishay Sfernice P16F and PA16F are designed to simplify designs and optimize costs in industrial and audio applications.
By integrating a knob with a panel potentiometer in a single component, the devices released today eliminate the need to purchase and assemble a separate knob. Furthermore, with only the mounting hardware and terminals situated on the back side of the panel, the compact potentiometers reduce the clearance required behind the panel to an extremely low < 15 mm.
With a conductive plastic resistive element, the PA16F is designed for audio applications, while the cermet P16F is intended for industrial motor drives, welding equipment, HVAC and lighting systems, and control panels. With their full IP67 sealing, the devices deliver reliable operation in extreme environmental conditions.
The potentiometers are available with custom knob markings, resistance values, wires, and connectors, in addition to detent and switch options. The devices are also available with a metallic knob on request. The P16F and PA16F are tested in accordance with CECC 41000 or IEC 60393-1.
