OHE1 are standalone, non-contact safety switches. With 2 OSSD safety outputs and 1NC contact, capable of switching 2A at 24Vdc. The OHE1 is magnetically coded and the OSSD outputs are suitable for series connection up to 30off, maintaining PL-e.

The OHE1 includes dual RGB LEDs for advanced on-switch diagnostics and the overhanging design improves visibility in awkward mounting positions. The OHE1 safety switches are available with 5-PIN, 8-PIN and 12-PIN M12 quick disconnect which are fully sealed and suitable for use in most wet / harsh environments.

The O-Type switches can be used with a fea­ture called EDM (external device monitor­ing). This means you can monitor the state of contactors or safety relays in order to detect failure of the external device eliminating the need for a safety monitoring device.
