An infrared sensing curtain for elevator door-opening protection, using 17 emitter/receiver pairs with up to 96 detection beams.
The transmitter and receiver are installed on opposite sides of the doorway. An interrupted beam provides an obstacle-detection signal for the elevator door-control system.

Align the transmitter and receiver within the permitted displacement limits and keep the optical path clear. Select the required NPN, PNP or relay output version to suit the controller input.
The maximum and minimum beam counts depend on the distance between the two curtain edges. Check the 2,000 mm overall height and the required detection distance against the doorway installation.
The exact product image shows a paired light-curtain transmitter and receiver with attached cables and plugs. This confirms the visible construction only; it does not establish ratings or hidden interfaces.
Confirm protected height, profile length, beam specification, connector type, cable length and controller compatibility.
Confirm protected height, profile length, connector and cable arrangement, supply/output interface and controller compatibility from the exact model documentation.
