    Hi friends
    I have make circuit for following operation. I am not form electronics but some how i have to do the same from my own.

    Operation:
    I have 3 nos of e18-d80nk adjustable ir sensors A, B, C which are placed at position in line.
    Now I also have 2 devices say X1 and X2 which can be operated by relay RL1 and RL2.

    The Operation is when an object J will come infront of A it have to activate RL1. The relay RL1 has to be stay activated until the object J passes through B's range. when B senses the object it should deactivate RL1 and RL2 has to be get activated. this state of RL1 and RL2 has to be retained until the object comes to the C. when Object comes to C it has to close all relays.

    Please help and suggest me some circuit for the same.


    Sorry if you cant understand my question due to my bad English.

    can you find english datasheets?
    i would like to point out the lower datasheet has a sorta block diagram of how to set it up.

    ok.. so to recap:
    object detected by A RL1 On RL2 Off
    Object detected by B RL1 Off and RL2 On
    Object detected by C, RL1 Off and RL2 Off
    These sensors are nifty.. and useful, the output is digital. when they detect an object, the output is low. let me have a think.

    i can get the output you need, i think, using 2 3-input AND gates and 3 inverters.
