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.
