NOTES & TABLES: All notes and tables referred to in the text can be found on the

back of this page.

Special Models of the HS35 Incremental Encoder are available with one or more of the

following certifications. Consult factory for details.

The HS35 com-

bines the rug-

ged, heavy-duty

features usually

associated with

shafted encod-

ers 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.
