【Description】

4-pin module with the following definitions: VCC (Power Positive), GND (Power Negative), DO (Digital Output), AO (Inactive).

【Applications】

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

【Features】

1. Uses imported slotted optocoupler sensor.

2. Slot width: 5mm.

3. Output status indicator LED: off for high level, on for low level.

4. Output high level when obstructed, low level when unobstructed.

5. Comparator output with clean signal, good waveform, and strong driving capability (exceeds 15mA).

6. Operating voltage: 3.3V-5V.

7. Output form: 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. Uses a wide voltage LM393 comparator.

【Module Instructions】

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

2. Module DO can be connected to a relay to create limit switches or other functions. It can also be connected to an active buzzer module to form an alarm.
