TYPE:

HS20 Incremental Optical Encoder

The HS20 is a compact, rugged encoder designed with the needs of the

small motor market in mind. It can be used where lighter duty encoders

are not suitable or cost effective. The compact design makes it easy to

incorporate into tight installations and the IP64 rating means it will

stand up to dust, dirt, and splashing liquids.

Other features include dual preloaded bearings for longevity and

stability, differential line driver outputs for noise immunity and a

standard, Euro-style 8-pin sealed connector for easy connectivity. A

specially designed, non-marring shaft clamp allows for easy installation

and eliminates shaft damage should you need to reinstall or reposition

the encoder on the shaft.
