The NIR-50-325 retroreflective infrared photoeye is an external entrapment protection device Type B1,
non-contact sensor for use with automatic gates and doors. Since the reflector directs the beam back to
the photoeye, wiring to the other side of the roadway is not needed. The NIR-50-325 operates up to 50 feet
over a voltage range of 12-30 VDC and 24-30 VAC. Two LED indicators provide status information
at a glance making set-up and alignment easy. The NIR-50-325 is configured for normally closed (NC) and
10K monitoring and complies with UL325 requirements.
