Laser Beam
Opening
Output opening for laser diode. (Laser beam Max output: 1
mW. Continuous Wavelength: 670nm).
For Non-contact operation the reflective tape is placed on the
rotating object. When the reflective tape passes the laser a
count is generated.
Effective distance from object to be measured can be from 127
mm to 1.5m (5 inches to 59 inches).
*Measuring Conditions: On reflective surfaces, it may be
necessary to paint the shaft black, to minimize false activation
of the sensor. Reflective tape size and the radius of the
moving object should be considered to get the most accurate
reading from the tachometer.
Warning: Do not look into the laser beam opening while in
operation. Staring at the laser beam directly can cause
eye damage.
