On the back of my Epson GT-1500 scanner I have a port called ADF (Automatic Document Feeder) and it seems to have 26 pins. I read that the most common are 9/15/25/50 D-sub connectors, but 26-pin (DB26?) does exist, just not as common: https://www.thorlabs.com/images/TabImages/DB26_3_F_500p.jpg The British serving hardware depot RS have the following product that could fit this port "d-sub,plastic dust cap for std 15/hd 26 contact plug" but I'm utterly confused by the measurements on the data sheets: http://www.datasheetlib.com/datasheet/1233217/dbe15p_northern-technologies.html The rough (metric) measurements I was able to take were as follows: • Top length: 2.3cm • Bottom length: 2cm • Height: 0.7mm IMG: https://cl.ly/1V2i1q2F3y0N Now going by the measures on this data sheet: http://docs-europe.electrocomponents.com/webdocs/0d78/0900766b80d78017.pdf it seems that 70524CLF best matches my measurements, so I would need the 70519CLF (the cap) but how come it's not the 25-pin, why the 15-pin? I am confused! If you could shed any light I would be grateful thank you!
In the interests of others I can now reveal that I have subsequently learnt that the number of pins has no bearing on the size of the plug, as I first assumed, and that the 26-pin layout fits into a standard DB15 socket. This particular configuration referred to as "DB-HD26" (HD meaning high density) will therefore require the 70524CLF (colour: red) cap from: http://docs-europe.electrocomponents.com/webdocs/0d78/0900766b80d78017.pdf I have not tried it out, but will do sometime this year and report back...
