By coupling 2 pieces back to back and sticking item

together in a bridge, the output voltage is doubled.

How to make a Biasing Magnetic Field

• Stick a rubber of ferrite biasing magemt

• Position an element between the poles of the permanent magnet.

Notes on Application

• Excute the solder of the lead line within 10 seconds at a temperature below 260°C

• To fix the ELEMENTS: When glue is used, DO NOT apply mechanical stress to the elements.

• Do not use this element in the dewy condition.
