Panel potentiometer lasts 2 million cycles

Vishay Intertechnology Inc.’s P11L panel potentiometer features up to four modules and a compact 12.5-mm size. While standard low-cost panel potentiometers reach 50,000 cycles, the P11L offers a long life of 2 million cycles, reducing the need for replacement parts, increasing reliability and lowering maintenance costs. The P11L panel potentiometer is optimized for CMOS amplifier gain, CMOS IC offset setting, motor speed control, and angle sensor applications in welding machines, air conditioning units, tooling machines, medical systems, X-ray equipment, trucks and tractors, and military and avionics systems. The device’s cermet element provides better stability than carbon elements while its 1.5kVRMS dielectric strength offers greater reliability and robustness. The Sfernice potentiometer provides standard resistance values of 1, 5, 10, and 50kΩ, with a contact resistance variation of 2 percent or 3Ω, and low TCR of ± 150ppm/°C.
