Santest GMR Series – GMR2
Induct-Sinusoidal Encoder
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.
extremely high resistant to harsh circumstances due to no electronic parts employed in the sensor integrated into hydraulic cylinder and can be used for equipment of such as steel-mill plant no wear-out expected since no mechanical contact between sensor-rod and sleeve resolution 6.25μm of absolute output, in addition incremental output is prepared.
