These switches have a transmitter and receiver built into the housing, eliminating the need to align components and measure sensing distance during installation. They detect an object moving at high speeds when it passes between the light source and receiver. They 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). Adjust the intensity of the light beam to better detect shiny or translucent objects. All have a plug that connects to cables with a socket (sold separately), allowing you to quickly connect and disconnect the switch.

These switches meet American, Canadian, and European safety standards. They’re rated IP67 for protection from dust and temporary submersion.

Fork switches, also known as slot sensors, have a receiver and transmitter that directly face each other. They only work with components that fit between the transmitter and receiver. Those with a laser beam have a narrower light beam than those with an LED beam, making them best for detecting small objects.

Angle switches have a receiver and transmitter that are at a right angle. Use them to detect objects that are too large to fit through fork switches, such as boxes.

Switches with an IO link connect to a programmable logic controller (PLC), so you can remotely change your settings, view measurements, and receive error messages from your PC. You need an IO link controller to connect. If you already have a controller, you must add IO link software. If you don’t, you’ll need IO link software with a configuration module, which includes a controller and cables.

Switches with PNP/NPN signal output automatically produce the type of signal output that is needed based on the device they are connected to.

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. IP69K rated switches are protected from high-pressure, high-temperature washdowns. NEMA 6P rated switches are protected from corrosion and washdowns.

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 IO Link connect to a programmable logic controller (PLC), so you can change settings and receive error messages remotely. You need an IO-Link controller (not included) to connect.

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

In a single device, continuously monitor the distance of items and turn equipment on and off based on their position. They're photoelectric sensors—a light beam detects subtle changes at high speeds, like dents in cans on a bottling line. These transmitters send readings with IO link to a programmable logic controller (PLC), a human-machine interface (HMI), or a computer. Stall circuits on or off after they sense an object using the time delay function. All are rated IP67 and IP69K for protection from dust, temporary submersion, and high-pressure washdowns.

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

Monitor the color of products as they pass by on your line. These transmitters don’t just detect if color is in mint condition—they also turn equipment on or off, all with a single device. They’re often used for quality control in printing and packaging lines. For instance, if ink runs low and causes a color’s hue to fade, they can send a signal to pause production. The photoelectric sensor uses a highly accurate LED beam that combines red, green, and blue (RGB), which detects the slightest shifts in color at high speeds. It can even sense gradual color changes on glossy and mirrored surfaces. Rated IP67, these transmitters are protected against dust and temporary submersion.

Transmitters with IO Link translate and send readings to control systems, such as computers, programmable logic controllers (PLCs), and human-machine interfaces (HMIs). This also lets you send commands from your control system to these transmitters. Since they have a PNP/NPN signal output, they automatically produce the type of signal output needed based on the device they’re connected to.

Cables with a socket (sold separately) connect transmitters to your control system or directly to compatible machinery.

Configure any of your IO Link devices—from sensors to switches—without a PC, outlet, or separate software. Use these programmers to set parameters, check the quality of runs, clone settings for other devices, and more. Whether you’re setting up a device for the first time or adjusting settings, the easy-to-use touchscreen makes for a smooth experience. Since these programmers are powered by a battery and small enough to carry, you can bring them wherever you need.

As soon as you connect your device, these programmers download its IO Device Description (IODD) file. This means you won’t need to manually input device details, saving you time to jump right into programming. Internal storage keeps IODD files and custom settings on hand for you. If you need extra space, insert a microSD card (not included) into these programmers before turning on the connected device.

Plug devices with M8 or M12 connections directly into the sockets on these programmers. If your device has wire leads, use the included adapter.

Detect when oil rises on water, foam forms on beer, and tanks empty, triggering pumps and valves in food and sanitary lines. These switches are 3-A and European Hygienic Engineering and Design Group (EHEDG) certified since they’re easy to keep clean. Highly polished, they prevent bacteria from growing. They also stand up to hot spraying water, chemicals, and cleaners common to food plants, thanks to their PEEK probe, stainless steel body, BSPP threads, and IP ratings. Their IP67 rating also means they won’t fail if under water temporarily.

To connect to automated systems and remote displays, these switches work with IO Link and 4-20 mA analog output, making them good for hard-to-reach areas. Program the colors on the LED indicator to tell you what the switch is sensing.

USP Class tested, the plastic in these switches won’t leach chemicals. They’re also C-UL listed and CE marked to meet Canadian and European safety standards.

Use quick-clamp adapters to connect these switches to quick-clamp sanitary tube fittings.

Note: Solids and liquids must have a dielectric constant of at least 1.5 to detect them.
