Have you ever been curious about the function of a specific piece of hardware but were too embarrassed to ask? Jump in and I'll do my best to answer.
I'll go first. It's some sort of Ethernet probe with a red sensor at the tip

barcode reader.
I found this in a cabinet where I work. Is it some sort of PoE injector?

It's a NEMA RJ-45 cord, you are correct that it is a PoE injector.

Looks like a barcode scanner for a hand-held ordering terminal.
I worked for a convenience store that had to use this god awful clunky hand held device with that same attatchment, we would use the pen to scan the barcode, and use the handheld to input qty, etc.
Then, (to make matters worse), you had to couple the terminal to a phone, with a strap, the thing would circumvent the phone using noise through the mouthpiece, and your order would be placed.

Like the other guys said, its a barcode scanner. Ottawa Public Library back in the 80s and 90s is the only place I remember seeing them. They also had benches lined with amber vt220 terminals to search for books which was dope as hell. These days, shitty web interface on locked down IE browsers that spit out errors all the fucking time

With that said, I would not plug that into an outlet seeing how sketchy that cable looks.
