Drives and Motors

MS TYPE CONNECTOR

The ZB Series shaft encoders are general
duty industrial rotary pulse generators. The
AU-ZBG models are for single channel sensing
for counting, one directional measuring or
speed applications. The AU-ZBH models
are for quadrature applications, allowing for
counting up and down along with speed and
direction measurements. A conversion bracket
is available to easily convert this encoder
into a length measuring sensor. They can be
direct-coupled to a machine shaft by means
of a flexible-bellows, spring, or rubber sleeve
type coupling that allows for axial and radial
misalignment. They can also be coupled with
light instrument timing-belts. Timing-belt
drives also allow convenient gear-up or gear­down speed ratio changes that can be useful
for obtaining non-standard PPR rates.

Note: NPN Transistor outputs have 1.5 KΩ
load resistors returned to supply for internal
feed back purposes. This does not interfere
with the ability to use these outputs as
conventional “Open-Collector” outputs as long
as the supply voltage for the ZB is supplied
by the indicator or control receiving its output
signal. The ZB’s internal load resistor also
allows the output to be used as a current
source, however, load current must be limited
to 1 mA maximum

Convert to Length Sensor

The length sensor conversion bracket, model
AU-LSCB1000, comes with a 3 m (10')
long, 4 wire shielded cable and a 6-pin MS
connector. The hinge clamp assembly–model
AU-LSAHC001, provides an easy method
for attachment and mounting of the rotary
encoder to be used as a length sensors with
the AU-LSCB1000 conversion bracket. This
can be used with one or two wheels as the
application requires.

Length Sensor
Measurement Accuracy

Factors which affect measurement accuracy
include measuring wheel accuracy and wear,
and material conditions. Ideally, materials
which are hard, thin and strong provide good
readings, conversely, soft, thick and elastic
materials can present problems in obtaining
true readings. The great majority of these
situations, where this effect is consistent, can
be compensated for by applying a multiplier
to the quadrature output pulse train so as to
obtain a corrected measurement. Counter
or Rate Indicators with “input scaling” can
compensate for measuring wheel wear and
material elastic and compliance errors.

Wheels–
Maximum Wheel Speed is 600 RPM

“F” style wheels are made with a tan
polyurethane tread and are used for soft,
smooth materials such as paper, matting,
cardboard and fine weave textiles. The broad
width minimizes contact pressure and the tan
polyurethane tread minimizes marking.
