Norstat now offers a full line of noncontact, magnetically operated safety switches. 

The O-type line of switches are available in two versions. The OHE1 is a standalone, noncontact safety switch with 2 OSSD safety outputs and 1NC contact and is magnetically coded. The ODNK is a standalone, noncontact, RFID safety switch with 2 OSSD safety outputs and 1NC contact. The uniquely coded RFID has a possible four billion code combinations, and both switches are suitable for series connection of up to 30 switches while still maintaining PL-e.         

The O-type safety switches have been designed for use on applications in which guard locking is not required. They are available in either uniquely coded RFID (yellow) or coded magnetic (black). The dual channel OSSD outputs can be used to reach a safety category of CAT4, SIL3, PL-e. The switches can be used with a feature called external device monitoring, which means you can monitor the state of contactors or safety relays to detect failure of the external device, eliminating the need for a safety monitoring device. The O-type safety switches are available with 3-, 6-, or 10-meter, prewired cables that are fully sealed and suitable for use in wet or harsh environments (IP67 and IP69K).  

The Magnasafe line of safety switches are reed and magnet operated and fully encapsulated, making them ideally suited for use in washdown areas, food processing, filling and packing industries, and other nonlocking, machine-guarding applications. Magnasafe switches are compact, noncontact safety switches that are designed for use with today’s modern safety relays. The switches are easy to install and maintain and have a short switching distance, making them tolerant to misalignment. Magnasafe switches are available with ABS or stainless steel, resin encapsulated housings, and they come in a wide range of sizes and contact arrangements. They are available in various cable lengths with quick disconnect options and carry a protection rating of IP67 and IP69K.
