Speed sensor module Counter module Motor test module Slot type optocoupler module

Definition of 4 pins VCC power supply positive, GND power supply negative, DO digital output, AO invalid

Use:

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

Module features:

1. Use imported slot type optocoupler sensor

2. Slot width 5mm.

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

4. If there is a blockage, the output is high level; if there is no blockage, the output is low level.

5. Comparator output, clean signal, good waveform, strong driving ability, more than 15mA.

6. Working voltage 3.3V-5V

7. Output form: digital switch output (0 and 1)

8. Fixed bolt holes are provided for easy installation

9. Small board PCB size: 3.2cm x 1.4cm

10. Use wide voltage LM393 comparator

Module usage instructions:

1. When there is no obstruction in the module slot, the receiving tube is turned on and the module DO outputs a low level. When it is blocked, DO outputs a high level;

2. The module DO can be connected to a relay to form a limit switch and other functions, or it can be connected to an active buzzer module to form an alarm.
