This came out of an ABS sensor. I let the smoke out on this one. I am a curious person and wanted to see what the output was on the oscilloscope (and that is when the smoke came out). Not wanting to have that happen again, I dissected the broken one and went looking for a datasheet. I have not found one (in the USA) so I figured I would try this forum to see if there was someone that may recognise this. It has 2 pins (one is broken) and activates off a reluctor ring (toner ring) usually in the brake assembly or bearing of a vehicle. This one (I am being told) is from a 2015-2017 Ford Ranger (which was not produced in the USA.
These are made by Infineon:

RobertCNelson…you rock! Thanks for the information.
Looks like we can get a full datasheet from here: TLE4941PLUSC - Infineon Technologies
Test Circuit:
Regards,
Sorry to be a bother again. What I can read from this sensor datasheet is that it is activated by a magnetic source. The reluctor (toner) ring is not magnetic (to my knowledge). Would this sensor still work with just ferrous metal passing by it? It is 100% possible that I am reading the datasheet wrong…I know just enough to get myself in a heap of trouble.
Part number TLE4941PLUSCXAMA1 is a hall effect sensor, so it would not work with ferrous metals.
If there is a magnet behind the sensor, then the moving ferrous metal in front of the sensor will change the field and make the hall sensor switch.

Verifying @PaulHutch’s point, from page 3 of the datasheet:
