IR OPTICAL LIMIT SWITCH ENDSTOP TACHOMETER SPEED SENSOR MODULE FOR ARDUINO

This IR Optical Limit Switch & Speed Sensor Module is designed for accurate non-contact detection of object movement, direction, and end-stop positions. Commonly used in 3D printers, CNC machines, robotics, and tachometer projects, this module utilizes an infrared transmitter-receiver pair to detect the presence or absence of an object within its optical slot. The sensor outputs a digital signal based on the interruption of its IR beam, making it highly suitable for use as an endstop switch, tachometer, or rotary encoder. It’s fully compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers and supports plug-and-play integration with minimal programming effort.

Key Features:

• Infrared optical slot sensor for accurate non-contact object detection
• Ideal for use as limit switch, endstop, tachometer, or encoder module
• Compatible with Arduino, ESP32, Raspberry Pi, and other microcontrollers
• 3-pin interface: VCC, GND, and digital output (DO)
• Fast response time, high stability, and reliable triggering
• Compact size with onboard signal conditioning for easy integration
