Opto Theory
The opto receiver (Photo Transistor) should be approximately 0.1 - 0.7 volts when the opto beam
is unblocked and approximately 11 - 13 volts when the opto beam is blocked. The opto
transmitter (LED) should always be approximately 1.4 volts.
Note:
The transmitter (LED) is
larger than the receiver (Photo Transistor); it protrudes further from its case.
