thanks for the reply but i dont think that is a photo sensor because i can't see the diode in all pins , with multimeter on diode scale, and also i have several parts and all the same.

It's a dark and small place to take a picture but is a little piece of metal bolted in the disc that pass in the slot.

It sure looks like a slotted opto sensor to me.
Then the transmitter would be an IR LED and the receiver would (probably) be a phototransistor with connections only to the emitter and collector.
The LED might look like a diode if your meter provides enough voltage but the transistor would open circuit in both directions.

In first place i like to thanks the time spend in trying to solve my doubt and in second finish this thread because it is in fact a opto transitor.
i test all in a circuit and someones are ok and others not ok , i think the led's gone.
Thanks.
