Rotary Encoder

Rotary Encoder – Absolute & Incremental

Rotary encoders are essential devices used to measure rotational speeds, positions, lengths, angles, and velocities. They work by converting mechanical movement into electrical signals, which can then be processed by PLCs, industrial PCs, tachometers, and counters.

There are two main types of rotary encoders:

• Absolute Encoders: Provide a unique signal for each position and can resume accurate operation immediately after a power loss.
• Incremental Encoders: Output pulses relative to movement and require an initial reference point after power-up.

Encoders are available in both solid shaft and hollow shaft designs. Hollow shaft encoders can be mounted directly onto a motor or machine shaft, offering a space-saving installation solution.

Applications of Rotary Encoders

Rotary encoders are widely used in industrial environments, including:

• Automation technology
• Mechanical engineering
• Packaging machinery
• Handling and robotics
• Conveyor systems

For most industrial uses, magnetic rotary encoders are preferred due to their durability and resistance to shock, vibration, and dust compared to optical types.
