HEM 16 Linear Motion Potentiometer

Linear Displacement Transducer

Rectilinear potentiometric displacement transducer without shaft. Completely waterproof (IP68), designed to work with high pressure applications (250bar static, 400bar peak) such as hydraulic cylinders. The HEM series is characterized by an external magnetic actuator coupled to an internal measurement cursor, high precision and a life span up to 100 million cycles.

- 50mm to 1000mm stroke lengths

- Linearity tolerance ±0.05% (>100mm stroke length)

- Completely sealed, IP68
