UNIVERSAL (CHANGZHOU) ELECTRONICS CO.,LTD.

This magnetic transducer is compact in size. It is used for transforming mechanical energy into electrical energy, which consists of a magnetic field including a variable-reluctance path and a coil surrounding all or a part of this path, so that variation in reluctance leads to a variation in the magnetic flux through the coil and a corresponding induced electromotive force.
 
  Rated voltage: 5V. 
  Rated frequency: 2,731Hz. 
  Coil resistance: 15&plusmn;3&Omega;. 
  Operating temperature: -20℃ to +70℃. 
  Housing material: LCP.
