We see from your search that you're looking for information on the term "Hall-effect",
and we have a large number of manufacturers' news releases and technical articles here on Processingtalk which will be of interest.
Let me be your guide.
Start with
the news release Current sensors with 2100 V RMS isolation from
Allegro MicroSystems Europe, which we summarised at the time by saying "Allegro MicroSystems Europe has introduced two new families of high-performance low-noise Hall-effect current sensors, measuring 5A, 20A or 30A FS and featuring an isolation
voltage of 2100 V RMS".
A few weeks before,
we featured the news release Current sensors for automotive battery-monitoring from
LEM UK: "LEM introduces family of current sensors for automotive battery-monitoring applications offering accurate primary current measurements without breaking the battery power bus".
In November 2006, we covered the news from Hamlin Electronics Europe
concerning its 55505
- take a look at Geartooth sensor for automotive applications
which says: "World leading position and movement sensor solutions company Hamlin Electronics Europe has launched a new Hall-effect geartooth sensor designed specifically for automotive applications".
Take a look also at the news release from Penny + Giles, New low profile joystick handle for chest packs,
as well as Non-intrusive current sensors monitor batteries from LEM UK,
and IC integrates Hall element and motor control from Allegro MicroSystems Europe.
