What are the main types of Autonics Rotary Encoders used in automation?
The main types of Autonics Rotary Encoders used in automation are incremental encoders and absolute encoders. Both types perform the same basic task — converting rotational movement into electrical signals — but they differ in how they provide feedback to the control system. The incremental rotary encoder generates a series of pulses when the shaft rotates. The number of pulses per revolution determines its resolution and accuracy. These pulses help calculate the position, speed, and direction of rotation. Incremental encoders are simple, cost-effective, and widely used in applications like conveyor systems, speed monitoring, and motor control where continuous movement data is needed rather than exact position information.
The absolute rotary encoder, on the other hand, provides a unique digital code for every shaft position. This means even if the power goes off, the encoder remembers the exact position once power is restored. Absolute encoders are ideal for applications that require high precision and repeatability, such as robotic arms, CNC machines, and automated assembly systems. Autonics offers both single-turn and multi-turn absolute encoders, depending on how many rotations need to be tracked. Additionally, Autonics Rotary Encoders are available in various forms like shaft type, hollow shaft, and heavy-duty models, suitable for different mounting and environmental needs.
In short, the two main types — incremental and absolute Autonics Rotary Encoders — serve different roles but share the same goal: providing accurate motion feedback for industrial automation. Incremental encoders are best for speed and direction monitoring, while absolute encoders are used where exact position control is critical. Choosing the right encoder depends on the required precision, operating environment, and control system design.
