This is an adapter module for a Hall Effect sensor in a TO-92 LPG package. It allows you to position the sensor near a magnetic switch and read its values for building a keyboard. The mounting holes are compatible with SU120 PCBs, designed for M1.4 self-tapping screws.

The sensor holds firmly in place on its own and usually doesn’t require glue or anything similar (though you can use it if you prefer). For easier installation, I recommend first inserting the sensor the other way around and slightly bending the leads, then inserting it correctly (as shown in the photo).

Settings:

• I did it with 0.4mm nozzle
• First layer height: 0.2mm
• Layer height: 0.1mm
