We see from your search that you're looking for information on the term "Position Sensing",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Sealed sensors are positioned for long life from
Macro Sensors, which we summarised at the time by saying "Position sensors have no parts that wear out, offering unlimited cycle life and greater performance than a potentiometer".
A few weeks before,
we featured the news release Stroke transducer offers easy position sensing from
Magnet Schultz: "Magnet Schultz' LVDT stroke transducer matches existing analogue systems without adaptation and provides superior precision in relation to linearity deviation and temperature drift".
In September 2007, we covered the news from Pilz Automation Technology
concerning its PSEN ma1.3.
- take a look at Safety switches offer easy installation
which says: "The PSEN ma1.3 safety switch offers resistance to shock and vibration, an 8mm switching distance, an auxiliary contact as standard and an integrated status LED".
Take a look also at the news release from Macro Sensors, Position transducers suit tough environments,
as well as Hall-effect sensor paper planned from Allegro MicroSystems Europe,
and Optical encoder series expanded from Avago Technologies.
