(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) 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 鈥?0擄C to
+85擄C
for SR4P2-A1.
(5) To order 1 meter jacketed leads, replace the 1 at end of listing with a 2.
Example: SR3B-A2.
