Magnet Biased SMD Reed Sensors come in Normally Closed NC and Latching or Bistable types. These Reed Sensors use magnet biasing technique to convert a Normally Open sensor. The magnet strength and the Operate AT band are carefully selected and matched together and over molded. The final magnetic sensitivity of the Latching or Normally closed actuation is then calibrated with special equipment.

Biased sensors are polarity sensitive, capable of switching 10 W at 0.5 A, and can be actuated with a magnet having opposite polarity. Complete drawings, electrical and miscellaneous specifications, actuation distances, usage notes and Applications are listed.
