Magneto-electric rotation detector
MP-9820
Non-contact gear detection type
MP-9820 is a magneto-electric-rotation 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-4000 series tachometer and FV-1500 FV converter.
There are 3 types of detectors:
- General type：MP-981
- High speed type：MP-9820
- Water & acid proof type：AP-981
As for the MP-9820, the signal cable, extension cable, and connectors are sold separately.
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., S45C, SS400 etc.) |
* Module = Pitch circle diameter / Number of teeth
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 %.
