Operation
The FF-LS Series are through scan safety light curtains. Emitter circuitry (sensing unit A and B) transmits modulated,
infrared light that is detected by photoreceiver circuitry (sensing unit A and B). The number of light beams depends on the
protected height and resolution of the safety light curtain.
