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.
