June 30, 2017 —The Allen-Bradley GuardShield 450L safety light curtain system from Rockwell Automation is a solution designed to enhance safety while improving productivity through transceiver technology.
Unlike traditional safety light curtains based on pre-defined transmitter and receiver units, this light curtain system features a patented transceiver design that employs plug-in modules to establish each unit’s function as a transmitter or receiver. Once powered up, the transceiver learns its functionality from the plug-in module.
Five-pin plug-ins are available for basic on/off functionality, while eight-pin plug-ins provide manual and auto restart with external device monitoring (EDM). To further simplify setup, function settings are configured through dual in-line package (DIP) switches located on the plug-in module. Ideal for hand and finger detection, and offered in a range of protective heights, the light curtain system is also equipped with an active protective field that senses the entire length of the transceiver. This feature reduces the inactive sensing areas that generally appear at the top and bottom of other light curtains.
