Incremental Rotary Encoders
ARS B 37
Semi-Hollow Shaft, 37 mm Body - Magnetic Measurement
Semi-Hollow Shaft, 37 mm Body - Magnetic Measurement
The ARS B 37 uses magnetic measurement in a compact 37 mm body with semi-hollow shaft options. Its robust structure and IP54 rating make it ideal for demanding industrial environments where optical encoders would be susceptible to contamination.
Magnetic measurement - tolerates dust, oil mist, and vibration better than optical
Compact 37 mm body - fits tight installation spaces
Semi-hollow shaft - 4, 5, or 6 mm bore options
IP54 protection - suitable for factory environments
Lightweight ~90 g - minimises load on motor bearings
