The Genie OPGAKRPEN4X.S is a NEMA 4X rated monitored retro-reflective photoeye that combines the sender and receiver in a single housing, eliminating the need for power or wiring to the reflector on the opposite door jamb. A polarized beam and matching polarized reflector are used to suppress false triggers from shiny surfaces, and the active monitoring circuit generates a fault on wire cuts, reflector misalignment, or lens obstruction. The unit supports a maximum sensing range of 50 ft, making it suitable for doors up to 35 ft wide. UL 325 2010 approval covers momentary-close entrapment protection on all UL Listed Genie commercial operators. The heavy-duty metal shield housing provides mechanical protection for the sensor head in demanding commercial and industrial environments.
A: A retro-reflective photoeye houses both sender and receiver in one unit and uses a passive reflector on the opposite side; no power or wiring runs to the reflector, simplifying installation compared to a through-beam design.
A: Polarization prevents the sensor from detecting its own beam reflected off shiny vehicle surfaces or polished floors, reducing false triggers.
A: The active monitoring circuit detects wire cuts at the sensor, reflector misalignment that drops beam strength below threshold, and physical obstruction of the sensor lens.
A: The specified maximum sensing range is 50 ft, and the unit is approved for door openings up to 35 ft wide.
A: Yes, it is approved for all UL Listed Genie commercial operators and carries UL 325 2010 approval for monitored momentary-close entrapment protection.
