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.

Transmitters with three mounting holes are designed to fit on a three-hole servomotor face.

Connect transmitters to counters and controllers with cables (sold separately).

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

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.

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.
