Vishay / Sfernice REC 20 LR Precision Linear Position Sensors

Vishay / Sfernice REC 20 LR Precision Linear Position Sensors offer a measurement range up to 10mm with high accuracy of ±1%. These linear position sensors feature a long operating life of 4M cycles and essentially infinite resolution. The REC 20 LR Precision Linear Position Sensors are available in a compact 19mm x 37mm body, with a plastic housing and a stainless steel shaft. These linear position sensors are RoHS-compliant with exemptions and provide lead-free terminations. Typical applications include infrastructure integrity, digital farming, and industrial automation.
