Slide one of these transmitters onto a motor shaft in your application—they have a flexible mounting plate that compensates for shaft misalignment and vibration. Also known as encoders, these miniature transmitters convert rotary motion to an electrical signal that indicates distance, direction, and speed of travel. They're often used to automate servomotors, robotics, and assembly machines.

Transmitters have NPN Open Collector output that requires a pull-up resistor (not included) for operation. Output channel Z is also known as an index channel. You must use transmitters with a controller that has quadrature detection to get a 4X resolution increase. All meet IP64 for protection from dust and water spray.

Often used with servomotors, these transmitters have a mounting hole pattern that fits a three-hole 28 mm BC servomotor face. Also known as encoders, these miniature transmitters convert rotary motion to an electrical signal that indicates distance, direction, and speed of travel. They're commonly used in control systems to automate servomotors, robotics, and assembly machines.

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

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.

With a built-in controller and driver, 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 driver 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.

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.

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.

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.

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.

Holding torque is the force needed to move the shaft out of position when it’s 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 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.

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

This digital readout (DRO) system displays precise positioning on one axis. For use with machines that perform dry machining and cutting applications, such as table saws, band saws, planers, and drill presses. These scales have zero-position memory, also known as absolute (ABS) positioning, which retains the measuring position when the scale is off. A zero-set button lets you start measuring at any point.

Improve the accuracy of your manual milling machine when you retrofit it with one of these digital readout (DRO) systems. They measure and display precise tool positioning on two axes.

Install a digital readout (DRO) stop and fence system onto the setup for your miter, chop, or radial arm saw. It displays measurements on one axis, allowing you to cut pieces up to 94" with high precision.

Mount one of these digital readout (DRO) systems onto your manual lathe to increase its accuracy. They measure and display precise tool positioning on two axes.
