The 38HA and 37HA multiturn optical encoder with BiSS-C
Pewatron is launching two new multiturn encoders designed with high single turn resolution of 23 bits (> 8 million positions) and 16 bits multiturn resolution. These small blind hollow shaft encoders offers excellent performance and durability in a small diameter of max. 38 mm. The 38HA was developed using the newest cutting-edge energy harvesting technology. Thanks to Wiegand technology, the A38HA powers itself in OFF mode and requires no batteries or gears for counting the number of turns, making it maintenance free. If a smaller height is required, the lower cost model 37HA is available with 28mm height. This is reached by using external battery backup for the turn counts in OFF mode. Designed for use with robotics or CNC machines, this encoder's modern BiSS-C interface continuously transmits status data. Featuring a blind hollow shaft diameter up to 8 mm and mounted stator coupling, the unit can also operate at a wide range of temperatures from -20 °C to +105 °C.
