GMR Series High Temperature Linear Transducers


Induct-Sinusoidal Encoder

The GMR2/GMRC-200 series is a high-resolution robust linear encoder of which structure is simplified and can enjoy heat-resistant 120°C. Succeeding to GMR sensor principle of operation, sleeve dia has now widened Φ18mm and offering more robust structure. Detecting absolute position of each sleeve pair within one pitch of 51.2mm and incremental position over one pitch by counting pitches. GMR2 series are the semi-absolute linear encoder of 24 bits integrated data of one pitch absolute and pitch count. SC type has now been added making cable duct mount possible. They offer extremely high resistance to harsh circumstances due to no electronic parts employed in the sensor. They can also be integrated into hydraulic cylinders and can be used for applications such as steel-mill plants. No wear-out is expected due to no mechanical contact between sensor-rod and sleeve. The GMR2 provides an absolute output of 6.25μm resolution, in addition incremental output is prepared.
