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.

Photoelectric Distance-Measuring Transmitters
Nano

Micro
M12 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. Those with an OLED display show the measured distance in real time, so you can check readings at the transmitter. They connect to a smartphone via Bluetooth, so you can use an app to configure them remotely. They’re often used in restricted or hard to reach areas, since you can set the trigger distance and save common settings without access to the transmitter.

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.
