Rotatory Encoder

• Incremental Encoder: Provides relative position information and counts pulses based on rotation.
• Absolute Encoder: Provides exact position information in a specific range, without the need for reference or reset.

Resolution:

• Typically measured in pulses per revolution (PPR), with common values ranging from 10 to 1000 PPR or higher, depending on the encoder type.

Output Signal:

• Incremental Output: Typically produces square wave signals (A, B channels) for tracking rotational movement. The number of pulses generated per revolution depends on the resolution.
• Absolute Output: Often provides a digital value corresponding to the exact angle of the shaft.

Supply Voltage: Typically 5V DC (some models may operate at 3.3V or 12V)

Current Consumption: Typically ranges from 10mA to 50mA depending on the encoder model and load.

Output Mode:

• TTL (Transistor-Transistor Logic): Common for direct interfacing with microcontrollers.
• Push-Pull (Digital Output): Provides both high and low-level output.
• Open-Collector (requires pull-up resistors): Often used for longer cable runs.
