Brief Introduction

Definition of 4-pin： VCC power supply positive, GND power supply negative, DO digital output, AO invalid

Purpose

Widely used for motor speed detection, pulse counting, position limiting, etc.

Module features

1. Using imported slot type optocoupler sensors

2. Slot width 5mm.

3. There is an output status indicator light, with the output high-level light off and the output low-level light on.

4. There is obstruction, output high level; No obstruction, output low level.

5. The comparator output has a clean signal, good waveform, and strong driving capability, exceeding 15mA.

6. Working voltage 3.3V-5V

7. Output format: Digital switch output (0 and 1)

8. Equipped with fixed bolt holes for easy installation

9. Small PCB size: 3.2cm x 1.4cm

10. Using a wide voltage LM393 comparator

Module usage instructions

1.When there is no obstruction in the module slot, the receiving tube is conductive, and the module DO outputs a low level. When obstructed, the DO outputs a high level;

2. Module DO can be connected to relays to form limit switches and other functions, and can also be connected to active buzzer modules to form alarms.
