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.

Detect motion near your light fixture to turn lights on and off. Compared to switch-mount motion controls that detect from a single wall, these controls have a better view of the entire space since they sense motion from above. Also known as occupancy sensors, these controls have an infrared sensor that activates when it detects a change in heat. To work properly, they need an unobstructed view of your space. All have a time delay to turn lights off after a set time. Rated IP65, these controls are protected from washdowns.

These light controls monitor motion in a full circle for coverage in all directions. Those that cover 7,690 sq. ft. have lenses that can be swapped out to limit where they sense. Half-circle sensing lenses are best for concentrating coverage to a certain part of a room, such as a workstation or an entrance. Narrow sensing lenses are best for the end of aisles in spaces with high ceilings like those in warehouses and factories.

When the pedal is pressed, the built-in potentiometer adjusts the resistance to vary the speed for motor drives. These switches can be wired to either increase or decrease the current when actuated. All are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

Track distance, direction, and speed in tight spaces on machinery. Cylindrical and about half the size of standard position-measuring transmitters, these are often used on robot arms and crowded conveyors. Also known as encoders, they send motion data to your system by converting rotary motion into an electrical signal.

Incremental transmitters track how much a rotating shaft has turned relative to a reference point. They need to be reset after a power loss. Absolute transmitters give you the exact position of the shaft, even after a power loss. Multi-turn absolute transmitters count how many full turns a shaft makes. They’re often used to keep print rollers aligned over multiple rotations.

Transmitters with a shaft connect to a motor’s shaft with a flexible shaft coupling to fit different diameters. Transmitters with a shaft opening slide onto your motor's shaft. Their mounting plate flexes to compensate for your motor's vibration.

Transmitters with an NPN open collector pair with a resistor. Use these transmitters with a controller that has quadrature detection to get a 4X resolution increase. Transmitters with IO link let you set their resolution remotely when connected to a PLC, a human-machine interface (HMI), or a computer.

IP-rated transmitters are protected from dust and water.
