Developed to satisfy the latest IECEx and ATEX standards, the IDEM range of non-contact safety interlock switches provide explosion proof switching for hazardous conditions created within the petro-chemical, pharmaceutical, food processing and packaging industries. Made from stainless steel 316, these safety switches have been developed for non-contact guard door interlocking of hinged, sliding or removable guard doors. In addition to explosion proof switching and depending upon the risk assessment for the application, the CM3-Ex, RM-Ex and WM1-Ex series, can also be used in combination with any dual channel safety monitoring relays to provide high functional safety up to Category 4 and PLe ISO13849-1 or SIL3 EN62061. The magnetic sensing of these safety switches provides a wide sensing distance and high tolerance to misalignment after sensing.
Explosion proof protection and high functional safety in one device Electrical switching elements fully encapsulated Stainless steel 316 housing High temperature stability up to 80°C High tolerance to guard misalignment Resistance to many organic and inorganic chemicals IP67 protection Resistant to high temperature hosing and detergent wash down Functional safety up to PLe ISO13849-1
