HEIDENHAIN Corporation (Schaumburg, IL) has introduced low profile incremental rotary encoders with block commutation tracks for use in small-dimensioned servo motors. The encoders come equipped with a 35-mm housing diameter and can be connected to almost all standard subsequent electronics for control of digitally controlled servo motors (up to edge lengths of 40 mm and 55 mm). The 1023 encoder has an overall length of 35.2 mm max and an IP 64 rating for hazardous environments; the 1123 encoder has an overall length of 30.3 mm max and an IP 0 for general use. Both encoders have mounted stator couplings and blind hollow shafts.
