HS25 Incremental Optical Encoder
The HS25 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 cable gland.
This low-profile design,
just 2” deep, is easily mounted on a through shaft. Securing the encoder to the shaft
is simple with a collet-style single screw clamp. The optional anti-rotation tether block
maintains housing stability during operation. The HS25 is designed to accommodate
shafts up to 3/4” in diameter. With optional insulating inserts, it can be mounted on
smaller diameter shafts. Applications include motor feedback and vector control, paper
converting and printing industries, robotic control, web process control along with many
other applications.
