DC Metallic-Object Proximity Switches for Long Distances
Micro
M12 Plug
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.
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.
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.
Switches with IO Link can be configured remotely when connected to a PLC, a human-machine interface (HMI), or a computer. They let you remotely change your settings, view measurements, and receive error messages.
All are rated IP69K for protection from high-temperature, high-pressure washdowns.

Photoelectric Distance-Measuring Transmitters
Nano
M8 Plug
With a single device, continuously monitor the distance of moving items and turn equipment on and off based on their position. These transmitters use a light beam to detect subtle changes at high speeds, such as dents in cans on a canning line. They also have a time delay function, so you can keep circuits on or off for a set time after they sense an object. These transmitters use IO link to send readings to a programmable logic controller (PLC), a human-machine interface (HMI), or a computer.
All are IP rated for protection from dust and temporary submersion. Those rated IP69K also withstand high-pressure washdowns.
Transmitters with a plug connect to cables with a socket (sold separately), so you can quickly connect and disconnect the transmitter.

Photoelectric Color-Measuring Transmitters
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.
