Rotary and Linear Potentiometers - Contacting Technology

Request for Quote

BEI Sensors rotary and linear potentiometers feature contact technology in a rugged, yet small package size and weight. Additional features include resistance to electromagnetic interference (EMI), temperature stability and the ability to work at very high and low operating temperatures. As with any of our BEI Sensors products, we offer a wide variety of standard and custom/adapted solutions for demanding motion control applications.

Rotary potentiometers are available in wirewound, conductive plastic and hybrid configurations. Single or multi-turn configurations are available up to 3600º (10-turns) of motion. These rugged, reliable contact sensors can meet IP66/67 sealing requirements and provide operational life exceeding 10 million cycles. A variety of terminations are available, including integral connectors and flying leads. Adapted and custom solutions for are also available.

Linear potentiometers offer capabilities of over 1 meter of travel and 1 million meters of operational life at temperatures up to 300ºC. These linear position sensor devices can be incorporated into hydraulic/pneumatic cylinders, installed on circuit boards, or simply mounted to mechanical assemblies.
