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.

Also available: If you don’t see the switch you need, please select 6693T999 and specify manufacturer and manufacturer part number.

Turn the face on these switches to sense metallic objects from the front, sides, top, or bottom. They’re a good replacement for limit switches with actuators that often break when hit. Also known as inductive proximity switches, they detect objects even if they’re covered by water, oil, dirt, or a surface finish. They’re often used in conveyor and bin filling systems, refineries, and mills. Sensing distance is based on the type of material being sensed; the distance listed is for mild steel. LED status indicators on the corners mean you can check your switch from any angle. All switches meet American, Canadian, and European safety standards.

You can send PNP or NPN signals from these switches to programmable logic controllers (PLCs). Use Testers for Proximity and Photoelectric Switches to determine the signal output of a switch you’re replacing.

Flush switches, also known as embeddable and shielded switches, are more accurate than projecting switches at close range. They also won’t cause interference when mounted close together. The sensor face mounts evenly with any material, including metal.

Projecting switches, also called non-embeddable and unshielded switches, sense objects farther away than flush switches. But, they require the area around the sensor to be free of metal.

Switches with a 4-pole micro M12 plug connect to cables with a socket (sold separately), so you can quickly connect and disconnect them. To view switch wiring diagrams, select a part number and click Product Detail. Attach switches with screw terminals to optional M12 connectors with a receptacle to convert them to a standard 4-pole M12 plug.

All switches seal out dust and stand up to some submersion. IP69- and IP69K-rated switches also handle high-pressure washdowns.
