Norstat now offers a Non-Contact Safety Switch that incorporates RGB LED’s for advanced on switch diagnostics.
The Mechan Controls OHE1 is a stand alone, non-contact safety switch with 2 OSSD safety outputs and 1 NC contact that is capable of switching 2A at 24Vdc. The OHE1 is a magnetically coded switch which is suitable for series connection of up to 30off while still maintaining PL-e. The OHE1 includes dual RGB LEDs for advanced on-switch diagnostics and the overhanging design improves visibility in awkward mounting positions. These switches are available with 3, 6 or 10 meter pre-wired cables and can also be used with an EDM (external device monitoring) to monitor the state of contactors or safety relays in order to detect failures eliminating the need for a safety monitoring device.
