MX21 INSTA-MOUNT™
|
SERIES
MODULAR INCREMENTAL ROTARY OPTICAL ENCODER
Introduction
By the time you have read this first sentence, you could have installed
the model MX21 INSTA-MOUNT™ modular optical encoder. In addition
to its quick and easy installation, the MX21 is designed to operate with
jitter-free output signals without tight controls on shaft endplay, runout,
or perpendicularity. The new INSTA-MOUNT™ encoder is capable of
operating within a temperature range of -10°to +70°C, requiring less
than 30 milliamps of L.E.D. current, without degradation of output
signals and is short circuit protected.
The MX21 is perfectly suited for motor manufacturers and other high
volume OEMs. The INSTA-MOUNT™ Series encoder offers 5V TTL
compatible quadrature outputs with index and complements as options.
Axial shaft movements during operation, of ±0.010”, will not adversely
affect the output signals. Shaft runouts of 0.005” TIR can also be
absorbed by this device without affecting output signal performance.

INSTALLATION INSTRUCTIONS
Preparation
1. Inspect motor interface per MX21 Data Sheet or specification drawing.
2. Motor shaft must be free of burrs & other surface defects.
Installation
1. Motor shaft should NOT be rotating during initial encoder installation.
2. Hold encoder perpendicular to motor shaft. Guide the encoder onto the motor shaft, pushing encoder STRAIGHT on until it is flush against
the mount surface. Do NOT rock side to side.
3. Install two #4-40 mount screws. Do not fully tighten at this point. (Note: A thread sealant should be applied to the screw threads)
4. Rotate the motor shaft (300 RPM, minimum). Press the air-gap button until it bottoms to the top of the encoder momentarily, then release.
CAUTION: DO NOT press air-gap button while motor shaft is stationary. Button should only be pressed for one or two seconds while shaft
is rotating.
5. Tighten mounting screws fully. (recommended torque is 30 to 40 ounce inches.)
6. This completes the mechanical installation. Proceed with electrical connections as indicated on product data sheet or specification
drawing.
Removal
1. Motor shaft may be stationary or rotating up to 1000 RPM during encoder removal.
2. Remove two mounting screws.
3. Grasp encoder firmly and pull STRAIGHT off of the motor shaft. Do NOT rock side to side.
