Linear Motion Position-Measuring Transmitters
Measure the position of an object moving in a straight line. Also known as string pots, these transmitters have an extendable wire cable that measures the relative distance between two points. They convert measurements to an electrical signal for use in controlling system automation.
All are IP rated for some protection from dust. IP67-rated transmitters also seal out water when briefly submersed.

Linear Motion Potentiometers
Pair these potentiometers with a controller to monitor the position of moving parts or send instructions to an electrical system. They have a rod that slides back and forth against an internal resistor, which increases or decreases the voltage flowing out to your controller. To monitor the position of a moving part, such as a robotic component, connect it to the rod. As the part moves, it pushes the rod back and forth, which allows the controller to observe and report the part’s exact position. To use these potentiometers as part of a controls system, connect them to a volume slider or other manual control. When you move the slider, the controller converts its position into instructions for electrical equipment, such as adjusting volume levels. These potentiometers are also called variable output switches.

Magnetic Position-Measuring Transmitters
Nano
M8 Plug
Micro
M12 Plug
Continuously monitor your air cylinder rod’s position and turn the cylinder on and off with a single component. These transmitters send positioning data to computers, programmable logic controllers (PLCs), and human-machine interfaces (HMIs). They're often integrated into automated systems for tasks such as timing when certain steps of your process should take place and verifying dimensions for quality control. Rated IP67, these transmitters withstand temporary submersion.
Press the buttons on the switch to toggle between voltage and current outputs. These transmitters have a plug that connects to cables with a socket (not included) so you can quickly connect and disconnect the switch.

Photoelectric Distance-Measuring Transmitters
Nano
M8 Plug
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.

Tie Rod-Mount Proximity Switches for Sensor-Ready Hydraulic Cylinders
Send an electronic signal to your system when the piston reaches a certain location. Mount one or two of these sensors on a cylinder tie rod; they must be flush against the cylinder tube. An LED indicator shows the piston location. These switches are PNP (also called "sourcing") output, so they send energy onwards. PNP output is most common in solid-state relays and PLCs used in the United States and Europe.
