Eliminate the need to calculate the sensing distance when using different metals—these switches sense all metal at the same distance. Also known as inductive proximity switches, they remotely sense metallic objects even if they’re obscured by water, oil, dirt, or a surface finish. They’re often used with programmable logic controllers (PLCs). All meet American, Canadian, and European safety standards. They’re also rated IP66, IP68, and IP69K for protection against dust, temporary submersion, and high-pressure, high-temperature washdowns. Also known as K=1 sensors.

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. 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.

Stainless steel switches resist corrosion better than brass switches. They’re best for harsh environments.

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