With a narrow, flat body, these switches fit in tight spaces. They detect the presence or absence of an object moving at high speeds with a light beam. Adjust the intensity of the light beam to better detect shiny or translucent objects. All are rated NEMA 4X, 13, and IP67 for protection from corrosion, oil/coolant spraying, washdowns, and temporary submersion.

Direct sensing switches detect objects when light reflects back from the object. The transmitter and receiver are in the same housing, so they fit in confined spaces.

Receiver switches detect objects when an object breaks the light beam between the transmitter and receiver (both included). They have a longer sensing distance than direct-sensing and reflector switches.

Reflector switches detect an object when it passes between the switch and the reflector, interrupting the beam. They have a longer sensing distance than direct-sensing switches.

Switches with DC input voltage automatically produce either PNP or NPN signal output, based on the device they are connected to.

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

Sense objects from farther away than with other proximity switches that have the same diameter. 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 signal output. Some automatically sense whether PNP or NPN signal output is needed.

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 with the same diameter.

Switches with a 4-pole Micro M12 plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.

All are rated IP69K for protection from high-temperature, high-pressure washdowns. Some are also rated NEMA 6P, 13, and IP67 for protection from corrosion, oil/coolant spraying, and temporary submersion.
