Low Primer Sensor Conversion




Converting the Dillon Super 1050 Low Primer Sensor for use with the FFB Auto-Drive


Materials Required:

  • Dillon Low Primer Sensor.
  • Two feet of 18-20 AWG wire.  High strand count, flexible is preferred.
  • 1/4″ Mono Speaker Plug.  We like Digikey.com p/n 889-1828-ND.

Tools Required:

  • Philips Screwdriver
  • Wire cutter/stripper
  • Soldering Iron

Step 1 – Remove the 4 screws holding the sensor together.

Step 2 – Remove the switch and buzzer assembly.

Step 3 – Unsolder the RED wire from the switch.

Step 4 – Cut the 18-20 AWG wire to Two (2) feet in length.

Step 5 – Solder the wire to the normally open terminals as pictured on the side of the switch.  In our product photo, that is the bottom two terminals as pictured.

Step 6 – Solder the other end of the wire to the 1/4″ mono speaker plug.  There is no polarity of the wires.

Step 7 – Re-assemble sensor.

That’s it.  The conversion can be done in less than 5 minutes once all materials/tools are ready to go.  The speaker is no longer used and can be stored for later conversion back to stock, or tossed in the trash.

Warning:  Do not use any batteries in conjunction with the switch.  Doing so will damage the Variable Frequency Drive (VFD).
