Potentiometer with long life
22 November 2011
New panel potentiometer with long life to two million cycles and full IP67 sealing.
Vishay Intertechnology has announced a new cermet panel potentiometer that features long life to two million cycles and full IP67 sealing for reliable operation in extreme environmental conditions.
Featuring a heavy-duty construction, the Vishay Sfernice P13L potentiometer is optimised for use as a voltage divider operator interface for military applications, cameras, night-vision devices, and portable industrial or professional equipment requiring operator setting. The potentiometer reduces costs by eliminating the need to design and build sealed protection against dust and moisture for the device in these applications.
The P13L is available in six bushing options and body sizes of 12.6 mm, 14 mm, and 16 mm. Bushing L and N feature life of two million cycles, while bushing T, Q, O, and P offer one million cycles. For designers, the potentiometer's long life reduces the need for replacement parts, increasing reliability and lowering maintenance costs.
The P13L offers a high power rating to 1.5 W at + 70°C, tight TCR of ± 150 ppm/°C typical, and standard resistance values of 1 kΩ, 5 kΩ, 10 kΩ, and 50 kΩ. The device's cermet element provides better stability than carbon elements, while its 2,000 VRMS dielectric strength offers greater reliability and robustness. The P13L's high stability and independent linearity of ± 5% are guaranteed for the full life of the device.
The potentiometer is available in 3 mm, 4 mm, and 6 mm shaft diameters, and multiple shaft lengths. Compliant to RoHS directive 2002/95/EC and tested in accordance to CECC 41000 or IEC 60393-1, the device offers an operating temperature range of -55°C to +125°C to ensure reliable operation in high-temperature environments.
Samples and production quantities of the new P13L are available now, with lead times of 10 weeks for larger orders.
