Machine Safety - Light Curtains

Light curtain beam arrays provide an invisible safety wall around industrial work areas using infrared sensing technology. When an object breaks a beam, the NPN or PNP output is set high or low. A transmitter and receiver pair with functions such as blanking and muting are required to form one light curtain system. Systems are designed by selecting the desired protective height, number of beams, beam pitch, operating range, and detection capability.
