Light Ray Pair for Savaria LU/LA and Other Commercial Elevators

Direct replacement for legacy WECO light rays and light screens used in many LULA elevators, like those using the discontinued WECO-917B72-A110 light curtain system.

This universal door detector system functions as a modern infrared safety screen, improving elevator door safety with a dense field of 94 non-parallel infrared beams. Designed for side-opening or center-opening elevator doors, it provides fast, reliable detection of obstructions using synchronized light curtain technology. Commonly referred to as a light ray or door detector, this unit integrates easily in LULA systems where older sensors have been discontinued.
