When the desired output of a length sensor and wheel combination is either in feet or inch units, selection
of the proper combination is relatively straight forward. For example, with a 1-foot wheel circumference, a
1 PPR Rotary Pulse Generator will deliver 1 pulse/ft, 12 PPR would deliver 12 pulses/ft (1 pulse/inch); 100
PPR would yield 100 pulses/ft; and 120 PPR would permit measuring to 1/10th of an inch (1/120th of a foot).

ORDERING INFORMATION
INSTALLATION:
1. Slide ZMH over a fixed Ш5/8" (Ш0.625 +0/-0.005") shaft. The optional ZMH
Mounting Bracket (MBZM0001) is shown in the picture.
2. While rotating the ZMH clamp to apply a spring load, securely tighten the two
clamp bolts with a 5/32" (supplied) or 4 mm hex “L” key.
Note 1: A 1/2 – 20 bolt can be threaded into the end of the clamp to aid in
loading the spring as shown. If a 1/2 – 20 bolt is not handy, then a Ø0.45"or
smaller rod, bolt, screw driver etc. works as well.
Note 2: The spring should not be preloaded too much or it may come in
contact with the spring limit pins and the ZMH will not have sufficient
travel to accommodate variations in the surface height of the material
being measured. For most applications, the spring setting in its mid-range
(5-6 lbs.) is sufficient.
