    Hello.

    I am looking to build a simple circuit with a optoelectronic switch that will test if the sensor is working via an LED. The part is OPB815WZ from OPTEK Technology.

    Here is the datasheet for the part: http://www.optekinc.com/datasheets/OPB815.PDF

    I know how to wire the LED side, but I'm rusty on biasing the transistor side. Any suggestions or comments?

    Thanks.

    Install a led in series to pin 3; will turn on when there is coupling.

    Don't forget to add a current limiting resistor in the collector circuit. Are you looking for a Go-NoGo test or a quantitative one?

    Thank you all for the help. I just completed wiring it up and it seems to work fine. KMosfett to answer your question, the test will be a quantitative one.

    Thanks again!
