Elen Hall effect speed/RPM sensors detect without contact the rotary movement of phonic or toothed wheels and generally of any rotative device built in a ferrous material and provided with slots or prominent parts. They provide a frequency output signal of digital type that follow exactly the alternating sequence of presence and absence of ferrous material presented by the rotative device.
They find typical applications on engines, differential gears, transmissions, turbines, pumps, racks and are able to work under the most harsh conditions.
