The MGL series from IDEM are non-contact RFID coded switches that have been developed to provide and maintain a high level of functional safety whilst providing a reliable electromagnet door interlock. To cover various applications, the holding force ranges from 600N to 1500N. The coding is achieved using magnetic and RFID techniques, both principles need to be satisfied for the switch to operate safely. The RFID sensing provides a tamper resistant operation when the actuator is in the sensing range of the switch. These non-contact safety switches are available in stainless steel 316, high specification robust plastic or diecast metal housings and can be used in almost any environment including high pressure cleaning. The stainless steel 316 version has been designed with a stainless steel magnet and IP69K rating making it suitable for CIP and SIP processes. There are 2 LEDs that offer 5 diagnostic functions to the user. The MGL switches provide two safe switching outputs for use with the majority of popular safety relays as well as a semi-conductor auxiliary signal to indicate the door position, meaning it can achieve up to PLe/Category 4 to ISO13849-1. Master Code - by series (any actuator will operate any switch) this is used when unique door activation is not required, but the benefit of RFID makes it virtually impossible to be overridden or by-passed by simple means.

Note
The switch is Power to Lock and therefore consideration must be given in the event of a power failure to machines where a run down time is present before the hazard is removed.
