Vishay Intertechnology has announced a cermet panel potentiometer that features IP67 sealing for operation in harsh environmental conditions.
Featuring a heavy-duty construction, the company's 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 eliminates the need to design and build sealed protection against dust and moisture, according to the company.
The potentiometer is available in six bushing options and body sizes of 12.6, 14, and 16mm. Bushing L and N feature life of 2 million cycles, while bushing T, Q, O, and P offer 1 million cycles.
The potentiometer offers a power rating to 1.5W at 70°C, tight temperature co-efficient of resistance of ±150ppm/°C, and standard resistance values of 1, 5, 10, and 50kΩ. The potentiometer's cermet element provides good stability than carbon elements, while its 2,000VRMS dielectric strength offers reliability and robustness, claims the company.
The potentiometer is available in 3, 4, and 6mm 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 potentiometer operates from -55 to +125°C to ensure good operation in high-temperature environments.
