Request InfoKeyence Corp. of AmericaThe GS series of safety interlock switches from KEYENCE Corp. of America adds value to safety light curtains and safety area scanners. A redesigned actuator allows for much easier door closure and the ability to maintain door closure over time, even when doors and gates sag or machine vibration occurs. Large LED status indicators change colors depending on door status, allowing personnel to easily check if the door is open or closed from a distance. A small footprint allows for direct and flexible mounting, increasing the location options.See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2023 IssueFiber-coupled LED SourcesNewDEL™ fiber-coupled LED sources from LumeDEL LLC offer high brightness from the deep-UV to NIR for medical, biotech, and industrial applications.
