    a colleague gave me this cct and said it doesnt work.
    i want to know its purpose and why its not working.

    please help me out.

    im seeking a cct that will help me create a sensor which will be linked to a counter.

    its to count the metal sheets that flow through a printing line.

    please help me out.

    What is it about the circuit that supposedly does not work?

    Is the problem that the circuit works but perhaps not the way that it needs to work for your application? (ie. the load is powered when it should be off and off when it should be powered)
