Hall-Eect Multi-Turn Rotary Encoder
Series HSM22M
Specications are subject to change without notice
10 turn (=3600°) Hall rotary encoder
True-Power-On
Compact Ø22.5 mm housing
Ø6 mm Shaft
Sleeve bearing
5 V, 12 V or 24 V supply voltage
Voltage or current output
As option with redundant output electronic
High reliability in measurement value capturing and
processing
The rotary encoders from the HSM22M series are real
"True-Power-On" multiturn encoders, in which the output
signal always corresponds to the angle of rotation, even
if the angle of rotation changes during loss of supply
voltage. In the comparison to other multiturn rotary encoder
technologies and signal evaluation processing methods
the MEGATRON HSM22M ensures the highest level of
reliability and failure safety.
