Compact Rotary Encoders

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.

Rotary Encoder Kits


Shown with Wheel (Sold Separately)

In addition to a transmitter, these kits include a 6 _1/2-ft. cable and a mounting bracket. Also known as encoders, transmitters convert motion to an electrical signal to indicate distance, direction, and speed in process control and metering applications. These kits are commonly used to monitor the position or velocity of rotating equipment. You can also mount a wheel (not included) to measure distance in linear applications. Transmitters must be used with a controller that has quadrature detection to get a 4X resolution increase. Output channel Z is also known as an index channel.

Use a flexible shaft coupling (not included) to connect the transmitter shaft to a drive shaft.

Provide motion feedback to counters, controllers, and motor drives for automated motion control and measurement applications. Also known as encoders, transmitters convert rotary motion to an electrical signal so you can operate your system based on distance, direction, and speed of travel. These transmitters have pull-up resistor output. Since they have two shafts, you can mount them on either side to fit your setup.

Use a flexible shaft coupling (not included) to connect the transmitter shaft to a drive shaft.

Programmable Rotary Encoders

With adjustable settings for resolution and output type, these transmitters can be programmed to suit your changing processes. Also known as encoders, they convert a shaft’s rotary motion into an electrical signal that indicates distance, direction, and speed. They’re rated IP67, so they can withstand temporary submersion in water.

Encoders with Shaft

Sanitary Rotary Encoders

Also known as encoders, these sanitary transmitters convey motion to an electrical signal that conveys distance, direction, and speed. They’re often used in control systems to automate servomotors, robotics, and assembly machines in sanitary environments such as food and pharmaceutical plants. Made of corrosion-resistant stainless steel, they won’t rust from frequent washdowns with harsh cleaners. These transmitters are sealed and have a highly polished surface, leaving no room for bacteria to grow and making them easier to clean. They’re rated IP67 for protection from dust, high-pressure jets of water, and submersion in up to a meter of water for 30 minutes.

To achieve a 4X resolution increase, use these transmitters with a controller that has quadrature detection.

Use a flexible shaft coupling to connect the transmitter shaft to a drive shaft.

Stepper Motors with Integrated Motion Control

With a built-in controller and drive, these stepper motors come ready to program and operate. Connect them to a computer and use the free downloadable software to set them up. After that, the controller can store and run programs on its own. The controller communicates to the drive which directs the motor’s shaft to move in small, equal increments. When the shaft stops, it holds its position even when a counteracting force is applied to the load. All are bipolar hybrid stepper motors, which deliver greater torque, precision, and efficiency than other types of stepper motors.

Encoders—When relative positioning is critical, such as coordinating motion in a multi-axis system, choose a motor with an encoder. The encoder monitors the position of the shaft and reports back to the controller.

Maximum Holding Torque—Holding torque is the force needed to move the shaft out of position when it is stationary. When the shaft is in motion, torque generally decreases as speed increases. Use a torque-speed curve to confirm which motor will work for your application. Click on a part number and select “Product Detail” to view the curve for a motor.

Full Step Increment—Full step increment is the rotation of the shaft from one position to the next. A smaller full step increment means the rotor has more teeth, producing smoother and more precise motion. 1.8° is considered standard.

Step Resolution—You can adjust the step resolution down to _1/256 of a full step, which translates to 51,200 microsteps per revolution. Increasing the number of steps directs an even more precise position and reduces the step-step-step motion to mimic a smooth, continuous rotation. The higher the number of step resolution settings, the greater the flexibility you have for determining the size of the motor’s step.

Stepper Motors

Motor/Encoders

To improve positioning accuracy, these stepper motors have a built-in encoder that monitors the real-time speed and position of the shaft. It sends that data to a controller (not included), which adjusts or stops the shaft if it isn’t in the right place. This makes them useful when relative positioning is critical, such as when coordinating motion between two motors. Stepper motors are good for precise, repetitive movements. Similar to the hands of a clock, their shaft turns in small, equal increments for smooth motion. When the shaft stops, it holds its position even when a counteracting force is applied to the load. All are bipolar hybrid stepper motors, so the current can flow in both directions. This helps them deliver higher torque, precision, and efficiency than unipolar stepper motors.

All motors require a controller and drive (not included).

2 Shafts—When relative positioning is critical, such as coordinating motion in a multi-axis system, choose a motor with two shafts and mount an encoder (not included) on one of them. The encoder monitors the position of the shaft and reports back to the controller.

Precision Potentiometers

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.

Programmable Potentiometers

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.

Accessories and Replacements for Potentiometers

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.
