The short body on these switches makes them suitable for tight spaces. Also known as inductive proximity switches, they remotely sense metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. Sensing distance is based on the type of material being sensed. 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). All are rated IP67 for protection from temporary submersion.

Flush switches, also known as embeddable or shielded switches, can be mounted so that the sensor face is level with the surface of any material, including metal. They’re more accurate than projecting switches at close range and can be mounted close together without causing interference.

Switches with a plug connect to cables with a socket (sold separately) to quickly connect and disconnect the switch.

Projecting switches are also known as non-embeddable or unshielded switches. When mounting, make sure the area around the sensor face is free of metal. These switches have a longer sensing distance than flush switches with the same diameter.
