Speed ​​sensor module Module Module Motor Test Module Glot Coupling Module

The definition of the needle VCC power is positive, the GND power supply is negative, the DO digital output, AO is invalid

use:
It is widely used for motor speed detection, pulse counting, location limit, etc.
Module characteristics:
1. Use the imported groove -type optocoupler sensor
2. The width of the groove is 5mm.
3. There is an output state indicator, the output high -electricity is out, and the output low -electric flat light is on.
4. There are blocking, output high levels; no obstruction, low output low level.
5. The output of the comparator, the signal is clean, the waveform is good, the driver capacity is strong, more than 15mA.
6. Work voltage 3.3V-5V
7. Output form: Digital switching output (0 and 1)
8. There are fixed bolt holes for easy installation
9. Small board PCB size: 3.2cm x 1.4cm
10. Use width voltage LM393 comparator

Module use instructions:

1. When there is no obstruction in the module groove, the receiving tube is turned on, the module DO outputs low levels. When the blocking, the DO output high level;

2. The module DO can be connected to the relay to form functions such as limited switches. It can also be connected to the active bee lumator module to form alarm.
