The HE SERIES  from Mechan Controls has been specifically designed to be used as a stand-alone switch or combined with a safety relay to provide up to a CAT 4 level of safety.  The HE-Series are coded magnetic safety switches designed to combine the ease of use and lower maintenance of a simple magnetic safety switch along with the improved security, performance and indication of an electronic safety switch. These fully encapsulated switches withstand vibration, wash down and are suitable for most harsh environments, making them ideal for use in the food processing, filling or packing industries as well as many other non-locking machine guard applications.
