Cautions and Warnings
WARNING … Not to be used for Personnel Protection
Never use product as sensing devices for personnel protection. Doing so could cause
serious injury or death. These sensors do NOT include the self-checking redundant
circuitry necessary to allow their use in personnel safety applications. A sensor failure
or malfunction can cause either an energized or de-energized sensor output condition.
UL 325 Non-compliant.
Retroreflective photoeyes rely on a reflective surface (a reflector) for proper operation. In some cases
a vehicle with reflective surface at a given distance can act as a reflector and allow the gate to close on
a car.
EMX Industries Inc. assumes no responsibility in this case and all risk is on the installer, designer and
user of the gate system with a retroreflective photoeye. In case such risk is not acceptable, EMX
Industries Inc. strongly recommends the use of a through beam type of photoeye.
Product Overview
Product may be used for activation of gates or doors when the beam is interrupted. The NIR-50 fail-
safe reflective sensor uses an infrared signal that is returned from a reflector mounted on the
opposite side of the opening to be monitored.

Installation
Recommended alignment technique is to mount the NIR-50 at the desired location and hold reflector
about 2 or 3 feet in front of the unit and while watching the lights to assure that both remain lit, move
backward to the desired mounting location for the reflector. You may have to move the reflector up,
down, left or right to keep the reflector in the middle of the signal path. This assures the least
troublesome set up by keeping the reflector off the edges of the signal where any movement may take
it out of alignment. Note: the signal pattern is only 2 feet diameter.
