BEI Sensors HS35 User Manual

The HS35 Dual Output Encoder

HS35 Incremental Optical Encoder

The HS35 combines the rugged, heavy-duty features usually associated with shafted encoders into a hollow shaft style. Its design includes dual bearings and shaft seals

for NEMA 4, 13 and IP65 environmental ratings, a rugged metal

housing, and a sealed connector or cable gland. The HS35 accommodates shafts up to 1” in diameter. With optional insulating inserts, it can be mounted

on smaller diameter shafts. It can be mounted on a through shaft or a blind

shaft with a closed cover to maintain its environmental rating. The HS35 is also available with a dual output option (inset) to provide redundant encoder signals, dual resolutions, or to supply two separate controllers from a single encoder.

Applications include motor feedback and vector control, printing industries, robotic control, oil service industries, and web process control.

Special Models of the HS35 Incremental Encoder are available with one or more of the following certifications. Consult factory for details.
