self-contained light curtain system. Both systems include a separate transmitter and receiver detector which are available in slimline (10x28 mm) and leading edge (37.5x13 mm) aluminium profiles. The light curtain system generates multiple infrared light beams betweem the transmitter and receiver detectors. When one of these light beams are obstructed, an output is activated.
The remote light curtain system consists of a transmitter detector, receiver detector and controller. The series offers detectors with 16 to 64 parallel infrared light beams and a total height of 0.57 m to 2.10. m. The controller offers a choice between AC and DC, and the output can be selected between an NPN transistor output and relay output. The controller offers a choice between automatic and manual sensitivity adjustment via potentiometer. Light or dark function, and long and short range is switch selectable. The time-out function is configurable – the number of channels and the time-out time period is switch selectable.
The self-contained light curtain system consists of transmitter detector and receiver detector. The system is available as a 20 channel system which generates 94 crossed infrared light beams, and as a 40 channel system which generates 194 crossed infrared light beams. The series is available with a DC supply voltage, and the output can be chosen between transistor and solid state output. The system requires no on site set-up. The sensitivity is automatically adjusted for each individual channel. The transmitter detectors include a test input that may be used for either disabling or enabling the transmitting power temporarily for test purposes. The time-out function can be enabled or disabled via wire connection. The detectors are protected against reverse polarity of power supplies, test input and output signals. The output is protected against short circuit and inductive loads.
