What It Is
A rotary encoder is a type of position sensor. This particular model is an incremental optical rotary encoder, designed to convert rotational movement into digital signals. It functions as a mechanical transducer, sensing rotation and providing an output based on that movement. With its AB Two Phase output, it can indicate both the direction and amount of rotation. This encoder operates on a 5-24 VDC power supply and features a 6mm shaft.
Key Uses & Applications
This rotary encoder is essential for applications requiring precise measurement of rotation, position, or speed. It is commonly used in industrial automation, robotics, and CNC machinery where a controller needs accurate feedback on motor or shaft movement. Its ability to generate up to 1000 pulses per revolution makes it suitable for tasks demanding fine resolution. The AB Two Phase output allows for directional sensing, crucial for many control systems.
How to Choose
When selecting a rotary encoder, consider the required pulses per revolution (PPR) for your application’s precision needs. This model offers options from 50 to 1000 PPR. The shaft diameter of 6mm should match your mechanical setup. Verify that the operating voltage of 5-24 VDC is compatible with your power supply. Also, confirm that an NPN or Voltage output type is suitable for interfacing with your controller.
Grit / Spec Guide
This rotary encoder is available with several Pulses Per Revolution (PPR) specifications: 50, 100, 200, 360, 400, 600, 800, and 1000. Higher PPR values provide greater resolution for more precise rotational sensing. The 6mm shaft diameter is a fixed mechanical specification. It operates within a 5-24 VDC range. The AB Two Phase output is standard across all PPR variants, providing directional information.
Care & Safety
Ensure the rotary encoder is installed securely, with the 6mm shaft properly aligned to prevent strain on the bearings. Connect the 5-24 VDC power supply correctly, observing polarity. Avoid exceeding the maximum operating voltage. Protect the optical components from dust and moisture to maintain accurate performance. Do not apply excessive force to the shaft or housing, as this can damage the internal mechanism of the rotational sensor.
