IR Infrared Speed Sensor Module – L393 Counter – 3.3V-5V

XD-51 Speed Sensor Module Sensor Slot Type Optocoupler Counter Module DIY Kit


  • Widely used in motor speed detection, pulse counting, position limit, etc.
  • There is an output status indicator, output high level and the light is off, output low level and the light is on.
  • There is occlusion, output high level; no occlusion, output low level.
  • Comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA.
  • Working voltage 3.3V-5V
  • Output form: digital switch output (0 and 1)
  • With fixed bolt holes for easy installation
  • Small board PCB size: 3.2cm x 1.4cm/1.26 x 0.55″
  • Use a wide voltage LM393 comparator

Code: XD-51 Module

Module instructions:
1. When there is no occlusion in the module slot, the receiving tube is turned on, and the module DO outputs a low level. When occlusion, the DO outputs a high level;
2. The module DO can be connected with a relay to form a limit switch and other functions, and can also be connected with an active buzzer module to form an alarm.

Material: plastic
Size: 32*14*5mm/1.26*0.55*0.20″
