Using a 40H instead of a regular 40C
The 40H (Hall effect) is to be used for data acquisition systems that require a square wave input signal. It is typically easier to interface the #40H to digital systems and the #40H has somewhat better noise immunity than a regular #40 when used in electrically noisy environments.
