DESCRIPTION
The Avtron Model HS4 Incremental Encoder is a light mill duty speed
and position transducer (also known as tachometer or rotary pulse
generator), allowing operation down to zero RPM. The HS4 employs
Hall Effect magnetic sensing technology, and when coupled to a motor
or machine the encoder outputs a specific number of electrical Pulses
Per Revolution (PPR) that is directly proportional to shaft position (pulse
count) or speed (pulse rate).
The HS4 employs a hollow shaft and clamping collar to lock the
encoder to the motor shaft. An insert permits models to fit a broad
range of shaft sizes from 3/8" to 5/8" [6mm - 15mm]. An anti-rotation
tether prevents rotation of the encoder while allowing for shaft end
float and axial movement. The HS4 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 HS4 offers
optional Avtron flexible anti-rotation tethers 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.
