Lee Bullet Feeder Sensor

thingiverse

Bought a Lee Bullet loader for my Dillon 550B and wanted to have a way of reminding me when it was time to rotate the columns so I wouldn't load blanks. It won't tell you when the last bullet is in the tube, as in order to clear the slide connector, it needed to be mounted a little higher on the tube. It will let you know when you only have a few bullets left so you can watch it and rotate it when needed. This uses a 12V Heschen M30 Inductive Proximity Sensor Switch I got on Amazon; https://www.amazon.com/gp/product/B081NNN98M/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I found that lead and ciopper is less sensitive than iron so, after trial and error, I found I needed the 15mm distance found only on a 30mm diameter sensor. For a 12VDC power supply, I used a ALITOVE DC 12V 5A Power Supply Adapter Converter Transformer, Amazon; https://www.amazon.com/gp/product/B01GEA8PQA/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 but any 12VDC source will work. You also need an alert device, a 12V light or Buzzer will work. I used a DIGITEN AC DC 12V 22mm Red LED Flash Alarm 80dB Indicator Light Lamp with Buzzer, Amazon; https://www.amazon.com/gp/product/B017YL31OY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 The above power supply I used on the cartridge sensor and powder run out sensor (coming shortly) can be used to incorporate them all.
