Product Description

In the displacement sensor series HEM12 the mechanical detection of linear movement is done by a magnetic drag. Due to magnetic coupling the drag pulls the wiper sled inside the closed tube which contains the resistive sensor element. This cursor construction provides wearless movement of the magnetic drag and prevents ingress of dirt or dust to the sensor element. On that way IP67 protection is reached for rough environmental conditions. For easy installation the tube contains a flange construction in fitting gauge or with thread. This flange construction provides also hydraulic applications up to 250 bar (450 bar peak). Because of his small dimensions and the cursor construction a space saving integration can be reached. To ensure high accuracy and long lifetime for a good price performance ratio the potentiometric measuring principle is realized with a high-resolution conductive plastic resistance element. Since the potentiometric measuring principle delivers absolute values and requires no electronic conversion, the position feedback signal is true power on without delay, temperature stable and robust against EMC influences.
