Features

  • Detects clockwise/anti-clockwise rotations: degrees and laps

    Specifications

    • Pulses per lap: 15
    • Power: 3.0V ~ 5.3V
    • Dimension: 32.1mm * 15.4mm
    • Mounting holes size: 2.0mm

    • Positioning in Industrial Controls

    How to Use

    In the case of working with a MCU:

    • VCCL: 3.0V ~ 5.3V
    • GND: power supply ground
    • SW: MCU.IO (encoder button status)
    • SIB: MCU.IO (output status)
    • SIA: MCU.IO (output status)

    Examples

    Connect the SIA, SIB, SW pins to the CH0, CH1, CH2 of logic analyser respectively, then power the module.

    When clockwise rotating the encoder, the output waveform looks like:

    When anti-clockwise rotating the encoder, the output waveform looks like:

    When pressing the encoder button, the output waveform looks like:
