A light curtain serves in the supervision of large areas.

Rrumba light curtains are one way light curtains, ie the sender and reciever are housed in separate casings.

There are several senders and recievers housed together in their respective casings. This makes for less complicated installation requirements as opposed to a comporable number of individually housed one way light gates. The distance between the individual beams of the curtain can be altered to suit the required function.

How they function:

By using light, in out case inrfa red light, objects are detected and thus a steering, sonar and/or regulatory function is started.

The light beams can be emitted in one of two ways.
