Contactless rev counters

Has anyone go any info on the Contactless brand of rev counters. Seems to have been used in both F1 and in the german DTM-series in late 80s early 90s

Are you sure you mean "Contactless" as a brand? There are many contactless instruments about - I have a contactless speedometer myself. I'm sure there are various contactless tachos which run off flywheel teeth, timing belt drive pulleys or their own timing wheels.

Im pretty sure it was a german brand, but i cant of course say for certain. Here are few examples of these rev counters.

From a F1 car


Mercedes Star branded


AMG branded

Judging from the Mercedes and AMG badges, its possible they are made by (or directly for) Mercedes and that the "contactless" badge is simply a feature like "injection" or "turbo". It may not, of course. Have you tried asking in the WTCC and European Touring Car forum? Someone there may have come across them.

Some new info. Looks like the Porsche 956 and probably 962 used both Boost gauge and rev counter from the very same manufacturer. Still only the Contactless logo can be seen. Looks like it says "Made in..." on the boost gauge. Perhaps Germany?
