BES 516-325-S4-C inductive proximity sensor

It detects metallic objects without contact and gives a PNP switching output, according to listings. The sensor has a nominal sensing distance of a few millimetres, and a plug-in M12 four-pin connector. The housing is made of nickel plated brass or stainless steel with a plastic sensing face, and it is rated to IP67. An LED indicates switching status. Operating voltage is typically 10 to 30 V DC. The 516 family is offered in flush and non-flush mounting types, and the S4 suffix indicates the M12 connector. Typical applications are position detection of metal parts on machines, end position detection of cylinders, counting, speed monitoring and presence detection in assembly and packaging lines.
