Time-Delay Fiber-Optic Photoelectric Switches
Set these switches to delay activation by up to fifteen seconds after detecting an object. They have a highly flexible fiber-optic cable and small sensing end, making it easy to position these switches in hard to reach areas. 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. The fiber-optic cable can be cut to length. All are rated NEMA 6P and IP67 for protection from corrosion, 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 switches.

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).
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 plug connect to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
Switches with IO link can be configured remotely when connected to a PLC, a human-machine interface (HMI), or a computer.
IP67 and IP68 rated switches are protected from temporary submersion. NEMA 6P rated switches are protected from corrosion and washdowns.

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.

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.

Harsh Environment DC Universal-Object Proximity Switches
Micro
M12 Plug
Rated NEMA 6P, 12, IP68 and IP69K, these switches protect against corrosion and high-pressure, high-temperature washdowns. Also known as capacitive proximity switches, they remotely sense both metallic and nonmetallic objects but their strength is in sensing materials such as plastic, ceramic, and clear targets. 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). They mount flush with the surface of any material, including metal, and are also known as embeddable or shielded switches. The 4-pole Micro M12 plug connects to cables with sockets (sold separately), allowing you to quickly connect and disconnect the switch.
