MODEL HS35 | INCREMENTAL OPTICAL ENCODER
Product Description
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.
