Are some Phoenix America Inc. magnetic proximity sensors more sensitive than others?
Most of the standard products are similar in sensitivity, but there are a few exceptions. The bipolar latching sensors, have relatively low gauss thresholds, allowing for somewhat wider airgaps. The most sensitive of all are custom desogned devices which use a highly sensitive GMR sensing element. These two devices are also omnipolar, meaning that they’re indifferent to the polarity of your magnet.
