HC-020K Double Speed Measuring Sensor Module w/ 20-Line Encoder Disc
The HC-020K is an optical encoder sensor module providing dual-channel TTL output for precise speed, position, and direction measurement of rotating shafts. It operates at 5V DC and is compatible with Arduino, Raspberry Pi, ESP32, and other microcontrollers for robotics and motor control applications.
Features
- Optical infrared photoelectric encoder with 20-line disc for 0.01mm resolution.
- Dual-channel (A & B) TTL output enables quadrature encoding for direction detection.
- High-speed measurement capability up to 100kHz frequency for stable performance.
- Compact module design with 4.5-5.5V DC operating voltage and low power consumption.
- Includes 24mm encoder disc and Jumper wires for immediate integration.

The HC-020K Double Speed Measuring Sensor Module utilizes an infrared LED and phototransistor pair to detect interruptions in light caused by a rotating slotted encoder disc. This optical principle generates clean, digital TTL pulses corresponding to shaft movement, enabling precise calculation of rotational speed and position.
Its dual-channel quadrature output (Channels A and B) provides a phase-shifted signal pair, allowing embedded systems and PLCs to determine both the magnitude and direction of rotation. The module’s 100kHz maximum measurement frequency ensures reliable data capture even in high-speed motor control, CNC spindle feedback, and conveyor belt monitoring scenarios.
