Light curtain system enhances safety and productivity

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.

“When light curtain systems are developed on the traditional transmitter/receiver architecture, customers need to buy multiple light curtain models to accommodate different features,” said Manfred Stein, global product manager, Safety Light Curtains, Rockwell Automation. “Now, they can purchase identical GuardShield 450L sticks and customise the features with different plug-ins.”   

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, advanced function settings are configured through dual in-line package (DIP) switches located on the plug-in module.

Suitable for hand and finger detection, and offered in a wide range of protective heights, the light curtain system is equipped with an active protective field that senses the entire length of the transceiver.

The active sensing field and compact design allow customers to install the GuardShield 450L light curtain system inside a machine frame. Additionally, flexible mounting kits and built-in alignment indication allow for quick, trouble-free installation.
