Choosing a Proximity Switch

IO Link Controllers and Modules

Create a system of sensors and actuators that you can remotely update, view measurements from, and receive error messages in real time.

Noncontact Switches

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.

Ultrasonic Switches

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

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.

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.

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.

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.

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

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.

Voltage-Monitoring Relays

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

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.

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.
