National Wheel-O-Vator LU/LA Elevator Door Light Curtain Set

Reliable 24V infrared light rays, suitable for replacing safety edges in select LU/LA elevators, including NWOV Evolution units that once used U1170, 2134103, or SAR-70 sensors.

Designed as a compact, modern replacement for legacy edge detection systems like U1170, 2134103, and SAR-70, this infrared safety edge unit delivers enhanced protection and easy installation for limited-use/limited-application (LU/LA) elevators.
Its compatibility with National Wheel-O-Vator (NWOV) Evolution EV12 units makes it a smart retrofit for aging systems, while its universal design suits various commercial LU/LA lifts requiring the same footprint and voltage.
This 79-beam configuration ensures dependable door obstruction detection using criss-crossed infrared technology; all without the need for external controllers.
