(1) A unipolar sensor has a plus maximum operate point and a plus minimum release point. One magnetic pole (south) is required to operate and
release a unipolar sensor.
(2) Abipolarsensorhasaplus(southpole)maximumoperatepointandaminus(northpole)minimumreleasepoint.Operateandreleasepointscan
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
