    Interesting to learn about the different sensor types.

    What method does the sensor for automotive anti-lock brakes use? It too reads a toothed gear.

    Thanks, Lee

    Origionally, they used a voltage generating pickup, like old electronic ignitions. Then they moved to hall sensors triggered from the gap. Lately, yet another option, as a cost saving measure, they use thin magnet rings with alternating N/S poles like brushless electrical motors use. At least those are the ones I am currently familiar with.

    Check out this link for hall effect gear sensors.

    I think coil, reluctor, pickups were used in early electronic distributors. The reluctor pickup is kinda large for use in a really small distributor. Remember it's a coil and as such requires some wraps of wire and a core. No doubt though they'd work. Autos used them for a long time.
