Choosing a Proximity Switch

DC Metallic-Object Proximity Switches

These switches use DC input voltage and produce PNP or NPN signal output. They're often used with programmable logic controllers (PLCs).

DC Metallic-Object Proximity
Switches for Long Distances

Sense objects from farther away than with other DC proximity switches that have the same diameter.

Easy-Install Photoelectric Switches

These switches have a receiver built into the housing, eliminating the need to align components and measure sensing distance during installation.

Photoelectric Switches

Detect the presence or absence of an object moving at high speeds with a light beam. These switches have a longer sensing distance than proximity and ultrasonic switches.

DC Universal-Object Proximity Switches

Often used with programmable logic controllers (PLCs), these switches use DC input voltage and produce PNP or NPN signal output.

Ultrasonic Switches

Detect objects and liquid or material levels to set off actions in your system—regardless of size, shape, or surface finish.

Photoelectric Distance-Measuring Transmitters

In a single device, continuously monitor the distance of items and turn equipment on and off based on their position.

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.

Magnetic Position-Measuring Transmitters

Continuously monitor your air cylinder rod’s position and turn the cylinder’s circuit on and off with a single component.

Hand-Held IO Link Programmers

Configure any of your IO Link devices—from sensors to switches—without a PC, outlet, or separate software.

Monitoring Relays

Voltage-Monitoring Relays

Safeguard your equipment against overheating, wear, and malfunction from a spike or dip in voltage.

Multifunction Monitoring Relays

Monitor phase, voltage, and frequency at the same time to protect motors, generators, and other three-phase circuits from burning out or overheating.

Current-Monitoring Relays

Protect electrical equipment from overcurrent and undercurrent damage—these relays continuously monitor current flow.

Ground-Fault Monitoring Relays

Detect and mitigate ground faults to prevent harm to equipment, circuits, and people.

Micro M12 Screw-Together Connectors

Because they tightly thread to M12 connections, these connectors won’t let contaminants in or come loose from vibration in rugged industrial environments and automated systems as they send power and signal or just power to your equipment.

Control of Liquids, Gases, and Solids

Humidity and Temperature Transmitters

These sensors measure temperature and humidity, then send the measurements to your PLC or controller to regulate heating and cooling equipment, alarms, and data recorders.

Infrared Thermometer Transmitters

Pressure and Vacuum
Transmitters with Digital Display

Monitor and control vacuum pumps, air compressors, and hydraulics while viewing readings and warnings on the display.

Pressure and Vacuum
Transmitters for Compressed Air

Specifically made for compressed air and gas systems, these transmitters remotely monitor pressure and vacuum.

Differential Pressure Transmitters
with Electronic Switch Outputs

Get the flexibility of a differential pressure transmitter and a switch in one. These transmitters can work as a traditional transmitter using an analog output but also have electronic switch outputs and IO Link compatibility, making them great for advanced automation applications.

Sanitary Level Switches

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.

Ultrasonic Transmitters

Measure the distance to objects and the level of liquids and materials despite size, shape, or surface finish, and send that information to other parts of your system.
