Heat-sinked potentiometer improves power dissipation

The Sfernice PE60 power-panel potentiometer from Vishay offers resistances from 1Ω to 1MΩ and a dielectric strength of 2500V_RMS in a compact, fully-sealed package. The Sfernice PE60 uses a Cermet element to offer a power rating of 6W at 50°C.

The Cermet element provides better stability than standard carbon elements, and the 2500VRMS dielectric and non-inductive design offer improved robustness. An operating temperature range of -55°C to 125°C ensures reliability even in extreme environments, and the device’s electrical performance meets CECC 41 000.

The potentiometer offers a 3% typical contact-resistance variation, and 1% typical end resistance. The device features a standard ±20% tolerance, with tolerances of ±5% and ±10% available on request.

The PE60 provides a maximum operating torque of 4.3oz-inch, and an end stop torque of 6lb-inch.

With a 25mm diameter, the Sfernice PE60 device is smaller than other power-panel potentiometers. Offering US and EU bushing threads, the PE60 is intended for industrial and aeronautic control panel and heavy-duty control applications. Custom shafts are also available in accordance to drawings supplied by customers.
