  • With block shape, you can easily use this sensor at mini sumo robots.
  • The sensor is working at 5V, gives NPN open collector output. (You should use with mcu which have pull-up function or add 10kohm resistor between signal and 5V line)

Cable Colors:

  • Yellow: NPN Output (Logic Level)
  • Red : 5V
  • White: 0V (GND)
