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.

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.

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.
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.

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.

Digital Position Indicators with Wireless Transmitters

Send the real-time position of machine parts moving along spindles, lead screws, and threaded shafts to your computer or programmable logic controller (PLC). These indicators help you make faster, more precise adjustments than you can with standard position indicators. They have built-in transmitters that wirelessly exchange data with a controller (sold separately) plugged into your computer or PLC up to 100 ft. away. These indicators save time and help prevent errors on packaging lines and other processes that you regularly adapt for diverse products. When it’s time to reposition a component, set the new target position on your computer or PLC, and the controller will relay it to these indicators.
More customizable than standard indicators, these digital indicators have programmable features that help you adapt them to your application. You can use these indicators as either a reference point or a true measure of distance. To measure distance, match the indicator’s count per revolution to your lead screw’s threads per inch or thread pitch. You can adjust them to count from their original position or from their most recent stopping point, which is useful for repeating moves. They also have settings to work with clockwise and counterclockwise rotation, as well as vertical and horizontal shafts.
Rated IP67, all are sealed against dust and water, even if briefly submerged.
Controllers (sold separately) are required. They can be used with up to 36 position indicators.
Add shaft reducer bushings to adapt indicators to fit small diameter shafts. Stainless steel bushings are more corrosion resistant than black-oxide steel bushings, so they’re better in humid locations.
