Courtesy: Rockwell Automation.The Allen-Bradley GuardShield 450L safety light curtain system from Rockwell Automation is a flexible, cost-effective solution that enhances safety while improving productivity through innovative transceiver technology. This next-generation 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). Advanced function settings are configured through dual in-line package (DIP) switches. The light curtain system is equipped with an active protective field that senses the length of the transceiver. This reduces the inactive sensing areas that generally appear at the top and bottom of other light curtains. The active sensing field and compact design allow customers to install the GuardShield 450L light curtain system inside a machine frame.
