(2) a bipolar sensor has a plus (south pole) maximum operate point and a minus (north pole) minimum release point. operate and release points can be both positive, or both negative. latching cannot be guaranteed. ring magnets are usually used with bipolar sensors. (3) an omnipolar sensor operates with any magnetic field (north or south pole). (4) operating characteristics are from 20 cto + 85 c for sr4p2-a1.
