The Haltech Hall Effect sensor has been in production for a number of years and it has been
a popular item due to it’s ability to be able to generate both home and trigger signals from the
one sensor.

The S3 and S4 sensors are used in conjunction with rare earth magnets which must be mounted in non-ferrous surrounds. It is vital to use Haltech supplied rare earth magnets. You may buy cheaper rare earth magnets at your local electronic store but there are many different types of rare earth magnets made from different materials and with greatly differing properties. Some magnets don’t have the required magnetic properties and others will fail at higher temperatures. Others will work correctly at first but will fail over time, particularly at high temperatures. The rare earth magnets supplied by Haltech are carefully chosen for their magnetic and temperature properties to give a long life even if operated at fairly high temperatures.
