Product description: Potentiometric Linear Transducer HEM12

The displacement sensors of series HEM12 are used in hydraulic applications with max. 250 bar, which require a robust linear transducer with high degree of protection, long lifetime and high accuracy in lengths from 50 to 1000 mm.

The linear potentiometers of the series HEM12 are designed for hydraulic applications with operating pressures of max. 250 bar and peak values of 400 bar. The mechanical detection of linear movements is done by a magnetic cursor. The construction prevents ingress of dirt or dust to the sensor element. On that way, IP67 protection is reached for rough environmental conditions. For mechanical coupling, the displacement sensors are available with internal or external flange.
The potentiometric distance measurement is carried out with a high-resolution conductive plastic resistive element. The displacement encoder has a very long lifetime and high accuracy due to its good linearity. 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.
Customization on the cable (length, finishing with plug) or on the push rod (length, thread, flat ...) are available on request.
