An Autonics Rotary Encoder is a motion-sensing device used to detect the position, speed, and rotation of a shaft or motor. It converts mechanical movement into electrical signals that can be read by controllers such as PLCs or microcontrollers. In simple terms, it tells your system how much and how fast something is rotating. Autonics offers both incremental and absolute rotary encoders, each designed for different control needs. Incremental encoders generate pulse signals during rotation to measure speed and direction, while absolute encoders provide a unique digital value for every shaft position, ensuring accurate feedback even after a power loss.
Here’s how an Autonics Rotary Encoder works. Inside the encoder, there’s a rotating disc with transparent and opaque sections. A light source and sensor detect the interruptions in light as the disc spins, converting them into electronic pulses. These pulses are then transmitted to a PLC or controller, which interprets them to determine position, angle, and movement direction. Depending on the model, Autonics encoders use different output types like NPN, PNP, or line driver, and communication methods such as RS-422 or Modbus. They are widely used in CNC machines, conveyors, packaging systems, and robotics for precise motion control.
In short, the Autonics Rotary Encoder plays a key role in automation by providing accurate rotational data to control speed, position, and direction. Its robust construction, high resolution, and reliable performance make it suitable for both light and heavy industrial applications. Whether it’s for simple speed detection or advanced position feedback, Autonics encoders ensure smooth and accurate operation in every motion control system.
