I have a couple of hall effect sensors from Jameco electronics, that I want to experiment with.Jameco has very little info. on them. They are RS41 by Honeywell but I can't find any examples of circuits or pin outs for them. If anyone knows the pinout or a circuit I could sure use the help. I have been searching the web for an hour and I found this site, but I still haven't found a circuit yet.

I want to build a electronic ignition for a small motor that I have, that is no longer made anymore.

Much better if you post schematic diagram of electronic ignition system. So we can match the RS41 Hall sensor.

I wish I could post a schematic, but I don't have a printer that is working. It is a very simple circuit. Just a automobile coil with a cap. in parallel and a MOSFET to ground, that will be controled by the sensor and amplifier. You can look at the second link I posted to see the sensors and amp. circuits, just add a MOSFET for the load.

Zoom in to fig 4. Left pin=VS, center Pin GND. Right Pin= OUT.

You can use Fig. 3 diagram #5 for scr. If your electronic Ignition project was CDI and SCR.

I won't need a capacitor discharge system. With just the MOSFET I can get 5000 volts spark, which is plenty. That's what my old Toyota has and it runs great. I know I could get a lot more than that, but I like the KISS method. Keep It Simple Stupid. ha.
I also have a couple other projects that I want to build with the sensors, but more on that later.

Hey. I like that KISS. It's another word I learned here in Electronics Point. The last one I learned was FFS from steve.:D:D:D
