Magnetic proximity sensors are now available in 8mm, 12mm or 18mm diameter and rectangular sizes with sensing ranges up to 70mm. NPN or PNP models are available along with normally-open or normally-closed outputs and built-in overload protection. New 8mm round sensors with M8 connector or attached 2m cable provide IEC IP67 protection. 12mm and 18mm diameter sensors with M12 connectors are available with standard IEC IP65/IP67 protection or with harsh duty IEC IP68/IP69K ratings. The 8mm, 12mm and 18mm diameter sensors have 316L stainless steel shielded housings. New rectangular magnetic sensors have a shielded polybutylene terephthalate housing with M8 connector or attached 2 meter cable and provide IEC IP67 protection. With a lifetime warranty, magnetic proximity sensors start at $44.50 and have cULus E32881, CE approvals.
