Datasheet

Vishay has announced a submersible cermet panel potentiometer that is said to be the industry's first fully IP68-sealed against deep-sea water. Featuring a stainless steel shaft and bushing, the P13SM is designed for applications in which electrical parameters need to be set with an immersed potentiometer in deep-sea saltwater conditions up to 30 meters (100 feet). The device achieves corrosion resistance times of up to 960 hours in a salt spray test.

Featuring a heavy-duty construction, the Vishay Sfernice potentiometer released today is optimized for use as a voltage divider operator interface for underwater equipment, submarine scooters, and lighthouses. The P13SM reduces costs by eliminating the need to design and build sealed protection against sea salt water for the device in these applications.

The P13SM offers a high power rating to 1.5 W at + 70 °C and tight TCR of ± 75 ppm/°C typical. The device's cermet element provides better stability than carbon elements, and it offers greater reliability and robustness.

The potentiometer is available in 3.17 mm and 6 mm shaft diameters and in multiple shaft lengths. The device offers a temperature range of - 55 °C to + 125 °C to ensure reliable operation even in extreme environments.

Samples and production quantities of the new P13SM are available now, with lead times of 10 weeks for larger orders.
