Rotary Motion Position-Measuring Transmitters

Shown with Wheel and Mounting Bracket (Both Sold Separately)

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. Transmitters have Pull-Up Resistor output.

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

Mount a wheel (not included) to use transmitters to measure lengths.

Use cables (not included) to connect transmitters to counters and controllers.

Transmitters with a quadrature output channel must be used with a controller that has quadrature detection to get a 4X resolution increase.

Rotary Motion Position-Measuring Transmitter 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.

Sanitary Rotary Motion Position-Measuring Transmitters

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.

Miniature Rotary Motion Position-Measuring Transmitters with Mounting Plate

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.

Linear Scales with Digital Readout

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.
