DESCRIPTION
The Avtron Model HS35A Hollow Shaft Rotary Incremental Encoder is a
speed and position incremental transducer (also known as tachometer
or rotary pulse generator). When mounted to a motor or machine, its
output is directly proportional to shaft position (pulse count) or speed
(pulse rate). The HS35A operates down to zero speed and can be used
for both control and instrumentation applications.
The HS35A employs a hollow shaft and clamping collar to lock the
encoder to the shaft. A high-performance resin hollow shaft insert
provides electrical isolation from motor shaft currents and permits
models to fit a broad range of shaft sizes from 1/2" to 1" [12mm -
20mm]. An anti-rotation bracket prevents rotation of the encoder while
allowing for shaft end float and axial movement. An optional protective
basket kit offers additional protection from impact and motor lifting
damage.The HS35A encoder offers 2Ø outputs (A,B) 90° apart for
direction sensing (A Quad B), with complements (A,B) and with
marker pulse and complement (Z,Z)
.
INSTALLATION CONSIDERATIONS
See page 3 and drawing on last page for shaft engagement rules.
Shaft may include keyway, but should not be flatted.
The HS35A offers optional Avtron flexible anti-rotation tethers/
brackets which will permit the encoder to tolerate ±0.1" of shaft end
float/axial movement. Select the proper tether for the application from
the table below.
CAUTION
Be careful not to damage clamping fingers of hollow
shaft during handling. Do not tighten clamping collar
before installation onto motor shaft.

WARNING
Installation should be performed only by qualified
personnel. Safety precautions must be taken to ensure
machinery cannot rotate and all sources of power are
removed during installation.
WARNING
Be certain to identify thread locker and anti-seize
compound correctly. Using anti-seize in place of
thread locker can cause mechanical failure leading to
equipment failure, damage, and harm to operators.
