Control a device with 10 times the precision as our standard potentiometers. With a resolution of 0.1% or less, these potentiometers fine-tune an electrical flow, so you get the exact brightness, loudness, or speed you need. For example, use them to control the speed of a conveyor so packages move at just the right pace for labeling. Unlike standard potentiometers, confirm your settings on the display. Also known as variable output switches.

Rated NEMA 13, these potentiometers protect against debris and splashing oil and coolant. Also known as variable output switches, they vary electrical flow to control speed, volume, and light intensity.

NEMA 4X rated potentiometers withstand weather, washdowns, and corrosion.

NEMA 6 potentiometers seal out water from temporary submersion as well as weather and washdowns.

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.

Create a seal around a potentiometer shaft to keep out moisture and dust.

For quick, repeatable adjustments to electronic equipment, these potentiometers adjust and save electrical settings. They’re typically used to control speed, volume, or light intensity. For example, if a conveyor needs different speeds for different tasks, you can program each speed into them. Set the digital display to show the specific measurement unit for your application, such as motor rpm.

Install them in a standard 1/8 DIN panel cutout. They’re NEMA 4X rated to resist corrosion, washdowns, and weather.

Adjust the brightness of lights.

Slide dimmers include both a switch and a dimmer. Use them to turn lights on and off while maintaining your desired brightness level.

Dimmers for LEDs only use the 0-10V dimming standard—pair them with 0-10V DC dimmable bulbs.

Three-way dimmers let you control the same circuit of lights from two locations, so they’re often used in large, open workspaces. Pair them with a 3-way on/off switch.

Control the brightness of desk lamps and other plug-in lights without altering your switch or outlet. Just plug these dimmers into the wall, then plug your light into the dimmer. They work with most types of light bulbs—just make sure your bulb is dimmable.

Adjust how bright lights are from anywhere. These dimmers use Wi-Fi to sync to a downloadable app on your smartphone or tablet. Use the app to set the brightness, turn lights on and off, and set a lighting schedule. For example, you might set the light to dim during peak sunlight hours. Someone working in the area is still able to turn the brightness up by pressing the top push button on the dimmer. Use up to 20 of these dimmers—even if they’re across different circuits—on the same Wi-Fi network.

Often used in large, open workspaces, these dimmers can be wired on opposite ends of the room to control the brightness of lights on the same circuit.

Often used with high-wattage lights, an external heat sink prevents these dimmers from overheating. They stick out from the wall 1/2 in. to help them disperse heat.

Brighten or dim your facility or workstation's light from a control panel. These dimmers fit through a standard panel cutout. Lightly press and hold your finger to adjust the light level. Rated IP67, these dimmers are so watertight they could even handle brief submersion. They also seal out dust.

Dimmers are great if you want to control the brightness from one place but turn the light on or off from a switch somewhere else. For example, you might want to dim a light over your storage area from a main control panel for energy efficiency but still be able to turn it on or off when you enter the area.

Dimmers with an on/off switch control power and brightness in one. Quickly tap them to turn the light on or off. When you turn it on, it returns to the last brightness level you set.

Fine-tune motion-sensing light controls from your smartphone or tablet. Mounting on the ceiling gives these light controls a clearer view of the room than wall-mount sensors, so they detect motion over a larger area. They connect to a free downloadable app using Bluetooth. Use the app to adjust the amount of time lights stay on after people leave, set schedules, or override the sensor so lights are always on. Also known as occupancy sensors, they turn lights on when they sense movement and off after people leave.

Controls with infrared sensors detect changes in heat sources and need a direct view of people.

Controls with infrared/ultrasonic sensors have two detection methods to minimize false activation: infrared to sense heat sources and ultrasonic to sense motion. Use the app to adjust whether both or just one of these triggers will switch the lights.

Controls with a dimmer let you adjust the brightness of your lights.

Add companion switches to control lights manually without having to wire them directly into the light circuit. Attach them to any interior wall or outlet box and pair them wirelessly on the app.

Control the brightness of lights from your smartphone. Using a Bluetooth-connected app on your phone or tablet, you can schedule when lights turn on, adjust their brightness levels, and set their movement sensitivity. Also known as occupancy sensors, these dimmers turn lights on when motion is detected and off when people are away. You can override the motion sensor function with a tap on the app to manually switch or dim lights. They fit in standard wall plates.

Dimmers with infrared sensors detect changes in heat sources and require a direct view of people occupying the space to activate.

Dimmers with infrared/ultrasonic sensors minimize false activation by detecting changes in heat sources and motion. They can be set so that only one or both detection methods are required to activate and hold lights on.

For light controls with DC input voltage, you'll need a power controller to switch a 120V or 277V AC lighting circuit. Power controllers have a relay that switches a maximum 20-amp load.

Also known as occupancy sensors, these controls turn lights on when movement is detected and off when an area is empty. They fit standard wall plates. All have a manual time delay that will turn lights off after a set amount of inactivity.

Dimming light controls adjust the light’s brightness.

Controls with infrared sensors detect changes in heat and require a direct view of the occupants. Controls with infrared/ultrasonic sensors detect changes in heat as well as motion to minimize false activations. You can set them to use one or both detection methods to activate and keep lights on.

Controls with an automatic time delay can turn lights off automatically based on usage patterns.

For light controls with 24V DC input voltage, you'll need a power controller to switch a 120- or 277-volt AC lighting circuit. Power controllers have a relay that switches a maximum 20-amp load.

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.
