content: Help me out. I got a whole bunch of random components that used to belong to an old timey that past away. RIP. I seriously enjoyed sifting through it all. There's some seriously cool stuff in there. Maybe i'll post some more pics later. There's some other stuff in there that has me scratching my head.

content: I'd guess an optical sensor and perhaps an emitter in the same package for a copy machine.

content: Have you ever seen a switch like this? I have a few of these. This is the bigger one. I even have spare parts for these switches LOL. Extra isolator pads and contacts. The shipping ticket/ invoice? wow.

content: Quote from: cvriv on January 16, 2022, 02:29:04 amYeah I have seen one like that. Its a 10-pole double throw switch with center-off position. They were used a lot in the telephone industry when operators ran switchboards with scores of these installed. The card looks like an inventory control card that was printed out with each item on an order from a customer to Kodak. All of the cards for a day would be read into an IBM computer with a card reader to keep track of inventory stock status after the stock was picked to ship.

content: the card in 0115222122_2-1024.jpg looks like a punch card. These were used to programm computers and for data storage/input before character terminals were available (e.g. 1940s-1960s).Yours probably was intended to be human and computer readable.https://www.computerhope.com/jargon/p/punccard.htm

content: Quote from: xrunner on January 16, 2022, 02:13:28 amI think you’re right:https://www.upi.com/Archives/1986/06/24/Kodak-unveils-high-volume-copiers/7582519969600/The only thing that makes me wonder is the date code on those boards — 1995 would be awfully late for a 9 year old product, I would think??

content: Quote from: xrunner on January 16, 2022, 02:13:28 amYes, those are reflective opto sensors. IR LED and Phototransistor in the same package. They're not as precise as the transmissive types, but useful for detecting the presence of a reflective object up to around 10mm.You should be able to identify the pinout by which half of the package the leads go into. The IR LED side should read about 1.2V forward voltage on a DMM diode test setting and then the phototransistor action should be visible on the resistance range with varying ambient light.Try run the LED at 10-20mA and the phototransistor with a ~10k pullup resistor to 5V as an experimental starting point.
