Allen Bradley Guardmaster Light Curtain, Transceiver, 0.5 to 4m Scanning Range - 450L-B4FN0300YD


Prevent accidents in your industrial environment using this light curtain from Rockwell Automation's Allen Bradley Guardmaster range. It projects a beam of light towards a compatible receiver in a hazardous area, which detects if a person is present and stops the machine from operating. Thanks to its patented technology, you can also use this transceiver as a receiver by simply inserting a plug-in module into it. This unit has a scanning range between 0.5 and 4m, which makes it a versatile choice.

• Beam resolution of 14mm to effectively detect items as small as a person's finger
• Two LED indicators for easy adjustment of alignment position
• IP65 rating indicates it's dust-tight and protected against low-pressure water jets
• Quick response time of less than 15ms for added safety
