| Element |
Characteristics |
| Semiconductor
magnetoresistive element (InSb) |
Wide dynamic range (detectable from
static sate to MHz order)
Wide gap characteristic
High output
Output will not be saturated even at high magnetic flux density.
Excellent environmental resistance
Temperature characteristics are provided.
Output sin wave distortion factor is low.
--> High multiplication output is enabled.
Polarity differentiation is disabled. |
| Hall element |
Wide dynamic range
Low output --> Used for Hall ICs
Polarity differentiation is enabled.
Magnetic flux density / output characteristic is linear. |
| Ferromagnetic thin film element |
Product sensitivity is high. Suitable for detection of
feeble magnetic fields.
Magnetic flux horizontal to element surface is detected.
Temperature characteristics are relatively excellent.
Output will be saturated depending on magnetic flux density.
Hysteresis is provided for magnetic flux density.
Gap characteristic is poor. |
| Coil pickup |
High output
High resolution
Temperature characteristics are excellent.
Output depends on speed. Detection of 20-Hz or lower frequency is
difficult.
It must be used in contact with the target material, because of its
poor gap characteristic. |
