Light electricity switch work principle

Jan 16, 2017

Pulse produced by the oscillation circuit with reflective de-vices, GL emit pulses of light from fluorescent tubes. When the measured range of objects into light, optical pulse is reflected back into the phototransistor DU. And demodulation of optical pulse in your receiver circuit for pulse signal, and then by strobe shaping amplifier and synchronization, and then use the numerical integration or RC points out, the last delay (or delay) trigger photoelectric switches drive output control signals.
