Hi, apologies for this question. I am not an expert in electronics.
I have been searching for a replacement of a photo sensor used on COLECOVISION roller ball controller. Attached a partial schematic of the rollerball controller, one of the sensors has failed. I have confirmed everything else works perfectly by reposition the working sensor in place of the bad one. I get no movement, no reading from the bad one.
Also I added few pictures of the sensor. I could not find anything on this part number, or the manufacturer. I then opened it, and would like to see if someone can help me confirming what kind it is. What would its internal schematics look like? Is this a photo transistor and a IR diode? There are a few sensors out there with similar dimensions, however I am not sure on the correct positioning of the pins vs. the original. The original has a #1 on the pin that connects to as shown (please consider this is a mirrored image because they are opposite when turning them around to face each other.) I tried to show it better in the other picture, where I wrote the correct pin # orientation. Hopefully someone can confirm with a diagram to be able to find a replacement. I need to know where the cathode/anode should be and the Collector/emitter should be. (if indeed this is a transistor)
Thanks in advance for your input.
