Hall Effect Proximity Switches/Sensors
-
ChenYang Technologies GmbH & Co. KG
A Hall Effect proximity switch is a non-contact electronic switch, which consist of a permanent magnet or ferromagnetic part as trigger intermediary and a Hall Effect sensor IC. The Hall sensor IC detects the change of the magnet field when the permanent magnet comes in the close proximity to it and generates an electric signal. This signal is amplified and rectified to control the output signal of the switch.

-
Wavecontrol presents a new and unique field probe for the measurement of electric and magnetic fields that integrates both E & H sensors within dimensions of only 3 cm². Which makes it unique is that Wavecontrol has managed to add an E field sensor in a basic structure of a classical 3 cm² field probe. It has been possible, therefore, to obtain a 3 cm² field probe without compromising the capability of assessing E and H fields of its 100 cm² big sister, the recognized and successful WP400.
