The wiring method of the slot -type photoelectric switch


Compared with the close switch, the optoelectronics switch is very long, and the test distance of the photoelectric switch is very long, and it is no contact type. High -energy detection small objects. The application is very wide.

The diode of the slot -type photoelectric switch is a light -emitting diode, the output is the light -sensitive triode, C is the set electrode, and E is the emission pole.

Generally, when used as switching, the triode is usually used as an output end.

General connection method: The diode is input, E grounded, C adapters, and the other end of the load needs to be connected to the positive power. The scope of this method of connection is relatively wide.

Special connection method: The diode is the input end, the C connection power is positive, the E -load, and the other end of the load needs to be grounded. This method of connection is only applicable to the time when the load equivalent resistance is very small (within dozens of ohms). If the effect resistance of the load is relatively large, it may cause the work point of the switching triode pipe to work abnormal, resulting in the unreliable switching work.
