Transceiver light curtain09 November 2017 | Automotive Manufacturing Solutions
The new Allen-Bradley GuardShield 450L safety light curtain system features transceiver technology says Rockwell Automation. The company says that unlike safety light curtains that use pre-defined transmitter and receiver units, this system 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). Rockwell says that to 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 range of protective heights, it’s claimed the active sensing field and compact design allow customers to install the GuardShield 450L light curtain system inside a machine frame.
