The WECO optical lightcurtain is used to detect an obstacle in the door entrance to the elevator cabin. It thus prevents the closing of the cabin door and the subsequent collision of the cabin wings with an obstacle in the entrance and possible damage to both the wings and the obstacle (person/cargo).
The WECO Type N optical curtain provides a wide range of mounting options with two C-channels; one on the side and one on the back. Side channel allows drilling in place. Suitable for static and dynamic installations.
The optical curtain WECO 03.G5.N46.1000 is equipped with 16 diodes that provide an optical network of 46 beams to detect an obstacle in the elevator door. The optical curtain has a detection distance of up to 4 meters, is made in IP54 protection and is resistant to sunlight.
With its profile height of 1000mm, this optical curtain is suitable for use in small freight and dining elevators.
The package of the optical lighcurtain includes a control unit for the cabin, optical strips (transmitter and receiver), extension cables, mounting accessories and a durable transport case.
