Description
HC-020K Double Speed Measuring Sensor Module HC020K
The HC-020K Double Speed Measuring Sensor Module is a high-precision optical sensor designed for real-time speed and direction detection in motors and mechanical systems. It uses an infrared reflective sensor paired with an encoder disc to accurately detect rotational movement, making it ideal for robotics, automation, CNC machinery, and motor control applications.
Features
- Dual Channel Output (A and B):
Provides quadrature encoder signals to detect both speed and direction of rotation. - High Accuracy:
Capable of measuring even small rotational changes with precision. - Compact and Lightweight:
Small form factor allows easy integration into tight spaces or compact projects. - Wide Voltage Range:
Operates reliably within 3.3V to 5V DC, suitable for Arduino, Raspberry Pi, and other microcontrollers. - Easy to Use:
Simple pin interface (VCC, GND, A, B) for plug-and-play installation. - Durable Construction:
Built with quality materials for long-term use in various environmental conditions.
