Kar-Tech’s Contactless Rotary Position Sensor delivers precise, reliable angular position feedback without the wear of traditional potentiometers. Its rugged anodized aluminum construction, encapsulated electronics and hall-effect technology eliminate mechanical contact for long-lasting, maintenance-free performance.
Designed for continuous 360° rotation, the sensor provides smooth, stepless position feedback with a linear 0.5V to 4.5V output. Its contactless design delivers an operational life exceeding 10 million cycles.
The Contactless Rotary Position Sensor is commonly used for boom rotation, steering angle and articulating arm position.
Unlike traditional rotary sensors that rely on wear-prone potentiometers, the Contactless Rotary Position Sensor uses hall-effect technology to deliver accurate, maintenance-free position sensing.
