PN series inductive proximity sensors are IP 69K-rated regular and short-body sensors with metal housings. These 10-30 VDC three-wire sensors are equipped with LED status indicators and are available with an attached two-meter output cable or M12 quick-disconnect. All styles are available with shielded or unshielded housings as well as normally-open or normally-closed and PNP or NPN output types. 12mm round PNM series sensors, with 4mm and 7mm sensing ranges, start at $18.75 ; 18mm round PNK series sensors, with 8mm and 12mm sensing ranges, start at $19.75 ; 30mm round PNT series sensors, with 15mm and 22mm sensing ranges, start at $25.00 . Backed by a lifetime warranty, PN series sensors are CE and RoHS approved; sensors with M12 quick disconnects are also cULus approved and sensors with two-meter cables are also UL approved.
