HS35 Absolute Encoder
Built on the same rugged design as the incremental model, the HS35
Absolute Encoder is available with various output options including
Gray Code and Natural Binary. Designed with a cast aluminum hous-
ing, a sealed connector and shaft seals, it carries an IP65 environ-
mental rating. With the optional insulating inserts, it can be mounted
on smaller diameter shafts. It is designed for either a through shaft
mounting or blind shaft mounting with a closed cover to maintain its
environmental rating.
