DC Metallic-Object Proximity Switches
Micro
M12 Plug
Also known as inductive proximity switches, these detect metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. Sensing distance is based on the target material. The distance listed is for mild steel. They’re often used with programmable logic controllers (PLCs) and produce PNP or NPN signal output. To determine the signal output of a switch you are replacing, use Testers for Proximity and Photoelectric Switches (not included).
Projecting switches, also known as non-embeddable or unshielded switches, must be mounted with the area around the sensor face free of metal. They have a longer sensing distance than flush switches with the same diameter.
Switches with a plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
IP67 and IP68 rated switches are protected from temporary submersion. NEMA 6P rated switches are protected from corrosion and washdowns.
Also available: If you don’t see the switch you need, please select 6693T999 and specify manufacturer and manufacturer part number.
