The NIR-50-325 is an extended range, retroreflective photoeye sensor providing entrapment protection for overhead doors, gates and barriers. The NIR-50-325 is UL325-2018 compliant and features an internal 10K resistor for monitored operation. Its flexible voltages, compact design and LED indicators make this photoeye easy to install.
The NIR-50-325 kit includes: photoeye with hood, reflector with hood, and mounting bracket with hardware.
This retroreflective photoeye is not compatible with operators that use NO and COM (non-10K) monitoring methods.
Ordering Notes:
Effective August 1, 2018Some installations may require the Protective Hood for the Photoeye and Reflector. They are available separately.
