The Relay Light Curtain is a fail-safe multiple thru-beam photo optic solution designed to provide a dense barrier of protection that, when interrupted, signals a door to stop and/or reverse. Light curtains are ideal for environments requiring extended vertical protection for protruding parts not detected by a standard single-beam photo eye. This device has a range of up to 32 feet and is available in 3-foot and 6-foot models. RLC is ideal for pre-2010 installations not requiring a monitored solution and can function as an additional device for added detection in any installation.
