The highly flexible fiber-optic cable and small sensing end make 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.

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.

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.

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.

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).

Detect objects and liquid or material levels to set off actions in your system—regardless of size, shape, or surface finish. These switches send out high-frequency sound waves that target small areas, so the surface and structure of your object won't affect results like photoelectric sensors, which sense using light. This makes them great for materials with uneven surfaces, such as granules and powder. They also sense objects when obscured by smoke, dust, debris, or water, but they don't work as well where there's wind, since it could disrupt their sound waves. Once an object is detected or a set level is reached, the digital output sends a signal to your controller to turn components in your system on or off. Use their plug to quickly connect and disconnect to cables with a socket (sold separately). UL listed, C-UL listed, and CE marked, all meet American, Canadian, and European safety standards.

Switches with two outputs let you set a minimum level on one output and a maximum on the other—for example, you can keep liquid levels constant by turning on a pump when the level drops too low and turning off the pump when it reaches the maximum.

Switches with PNP/NPN signal output automatically produce the signal you need based on the connected device.

90° elbow switches are compact to fit in tight spaces. They’re best for conveyors.

Rated IP67, all of these switches seal out dust and water if briefly submersed. NEMA 6 rated switches also stand up to weather and washdowns.

An infrared light beam senses the lightest finger contact to switch a circuit on or off. The included guard prevents accidental activation. An indicator lights up to confirm that switches are actuated. They’re rated NEMA 4X, 13, and IP66 for protection from corrosion, washdowns, and oil/coolant spraying.

Switches with a 5-pole mini plug can quickly be changed out.

Measure the level of conductive liquids without drilling a hole in your tank—these switches mount to the outside of the tank and track the capacitance between them and the tank’s contents. Use them on nonconductive plastic or glass wall tanks; they’re not compatible with metal tanks. They automatically adapt to your tank’s wall thickness, making them ready to use. These switches only respond when the liquid reaches the desired level, so foam and residue on the top of the liquid won’t trigger them early. For even more challenging setups, such as those with thick, sticky fluids, or if your tank has walls as thick as 10 mm, you can teach these switches to avoid false detections. All have LED indicators to show their power and output status.

Made of plastic, their body is chemical resistant and NEMA and IP rated, so it keeps out dust and dirt, as well as drips of oil and jets of hot water. UL listed, C-UL listed, and CE marked, they meet U.S., Canadian, and European Union safety standards.

Mount these switches directly on your sight glass using their adhesive back or use the included mounting bracket if you’ll need to remove them frequently. They also include foam pads for mounting them using straps around the outside of your tank.

PNP switches communicate with your system by sending a positive signal. NPN switches send a negative signal to communicate with your system.

Switches with an M8 4-pin connection have a standard plug that’s easy to connect. Switches with wire leads need to be hardwired, so use them in applications where you won’t move them often.

Use high-frequency sound waves to detect chemical level. This switch has three relays that can be programmed for multiple set points. Use it to activate several alarms or to automate tank filling and emptying. It’s rated NEMA 4X for protection from corrosion and washdowns.
