This is a speed sensor, the major goal is to check the rate of motor.
It was widely used in motor speed detection, pulse count, the position limit, etc.
Groove type optical coupling sensor
the output state light, lamp output level, the output low level light.
covered, output high level;Without sunscreen, the output low level.
the comparator output signal is clean, good waveform, driving ability is strong, for more than 15 ma.
has a fixed bolt hole, convenient installation
Groove width 10 mm.
the working voltage of 3.3 V to 5 V
output form: digital switch output (0 and 1)
PCB size: 2.3 cmx2cm
use the LM393 wide voltage comparator
