From Snowbum's page at

http://bmwmotorcycletech.info/Ignition.htm

"UNconfirmed information is that the Hall units may be found in 1979-85 VW; 1978-1983 Audi; 1979-1982 Porsche; and that Bosch 1237011052 may be the number."


Just food for thought

It would be useful if someone who has (or thinks they have) an automobile model and year with a suitable Hall effect sensor to post that information. For example, a 1968 BMW 2002 voltage regulator will work in a BMW airhead charging system. However, even if the automobile Hall effect sensor is correct type it still may not be suitable for installation in an airhead - or only offered as part of a replacement distributor.

An update for those interested

An update from Onlinecomponents:

Sir
This was discontinued by Honeywell when the division to which it belonged was sold to Sensata Technologies a few years ago.

They do not offer a comparable product and I am not immediately aware of a similar product being offered by our other vendors.

I placed an inquiry with Sensata to find out for you if they still support this and if so, through whom you would be able to purchase it.

Will advise.

Thank you for your inquiry.

Regards,

Might be time to check into alternative technologies. I wonder about using an LED with a sensor behind the notch.

No. Consider what happens to the light when it is dirty, or water flooded.

The 'other technology' used is a reluctance coil, or a pick up coil. But light sensing was given up a long time ago.

The Lumenition Optronic system has no troubles. I had one in my Rover and that engine got pretty flooded every so often. It's UV light, not visible.

The inside of your beancan stays pretty clean and dry anyway. if it didn't all the points-in-can bikes would have died long ago.

UV ... or the other side - InfraRed?

Either way light gets blocked by dirt, bent by water.
How many manufactures use a light based system in a production vehicle? The vast majority use a reluctance sensor or a hall effect.

here's how Lumenition optical ignition system is laid out. note optical disc that sits below ignition rotor has lobes that match number of cylinders. a four cylinder disc could be easily modded to two lobes. years back sold 200+ Lumenition systems for British sports cars. very reliable, very few come backs.

much easier to find a beancan with points

google it.

I made two points. The first concerning the realities of a londstanding successful manufactured product, seems to conflict with your armchair theorizing.

The second, concerning the cleanliness of the conditions that the sensor operates under, you conveniently ignore.

You do not know what's under the hood of everything out there. You have never designed and built equipment using optical sensors (I have, FWIW). Neither of us knows why capacitive sensors are used in some vehicles and opticals in others.
