DM-111A
Magneto-Resistance Element
For the availability of this product, please contact the sales office.
Description
The DM-111A is a highly sensitive magnetic
M-102 (Plastic)
resistance element, composed of an evaporated
ferromagnetic alloy on a silicon substrate. The
element can be used for detection of rotational
speed and for detection of angle of rotation and as a
detection of position.
Features
• Low power consumption
38µW (Typ.) at VCC=5V
• Low magnetic field and high sensitivity
75mVp-p (Typ.) at VCC=5V
and H=4000A/m
• High reliability
Ensured through silicon nitride protective filming
Absolute Maximum Ratings (Ta=25°C)
• Supply voltage

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.
