Rotation Sensor

Overview

• 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

Applications

• Positioning in Industrial Controls

How to Use

In the case of working with a MCU:

• VCC ↔ 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:
