Speed Sensor Module, Tacho-generator Counter

Speed Sensor Module Tacho Sensor Slot-type Optocoupler Tacho-generator Counter Module

Module for use:
✅Module slot unobstructed, receiver tube conduction module DO output low, when blocked, DO output high;
✅DO output interface can be directly connected to the microcontroller IO port, whether the sensor with barriers, such as the motor speed can be detected with the motor encoder.
✅DO module can be connected to relays, limit switches and other functional composition, and to be connected with active buzzer module, consisting of alarm.

Module features:
✅the use of imported groove coupler sensor, slot width 5mm.
✅output status indicator lamp output high, output low lights.
✅block, output high; no shelter, output low.
✅the comparator output signal clean, good waveform, driving ability, than 15mA.
✅the working voltage of 3.3V-5V
✅the output format: digital switching output (0 and 1)
✅a fixed bolt holes for easy installation
✅small PCB board size: 3.2cm x 1.4cm
✅using a wide voltage comparator LM393
