Non contact-type
Magnetoelectric detector
MP-9820 |
|
 |
MP-9820 is a
magnetoelectric-type detector using an internal hall
element, a permanent magnet, DC amplifier, and voltage
regulator in its compact body. Using MP-9820 in
combination with detection gear enables deriving stable
rectangular waveform from ultra low speed all the way
through high speed. (1 Hz to 100 kHz)
MP-9820 finds wide range of applications and
rotational measurement objects by using with TM-3100
series tachometer and FV-1400 / 5300 FV converter. |
Features
-
Wide range of signal detection from 1 Hz to
100 kHz
-
Achieve the highest level of frequency
response_Can be used in wide range of applications from low to
high speed and rotational measurement objects.
-
Neither load on measurement objects nor
worries about attrition or lubrication with non-contact
detection method.
-
Using an internal hall element and waveform
processing circuit in its compact body.
-
Adopting new type of cable greatly improves
in tolerance performance against electrical noise
Relationship between
detection distance and gear modules
Please use the
detective gear which is satisfied with the following
specifications.
| Shape of
gear |
Involute gear or
equivalent |
| Module * |
0.5 to 3 |
| Tooth
width |
3mm or more |
| Material |
Strong magnetic
properties
(e.g., S20C, SS400 etc.) |
* Module = Pitch

-
The detection
distance depends on the modules of detective
gear, with longer distances being possible with
larger modules. Also detection distance depends on
temperature. In cases where the ambient temperature
varies greatly, it should be mounted with minimum of
detection distance. The detectable range shown in
the right figure assumes an output waveform duty
cycle of 50 % ±20 %.
