Speed Sensor Module Tacho Sensor Slot-Type Optocoupler

• 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.

•  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
