Magnetic Gear Tooth Speed Sensor IMG Series
| Noise suppression technology for more accurate measurement. |
Constructed from two hall elements, a magnet, and a signal processing circuit.
It converts the difference of magnetism into the electric signal, and outputs the logic pulses.
| Jitter suppression | Detection section resistant to magnetic field noise. |
| Line driver output type | High resistance to noise to cables, even in long-distance wiring. |
| 0 - 20kHz Detection | Detects the starting motion and the movement at the time of stop finely. |
| -20°C to 105°C | Possible to use under high temperature environment. |
| Power supply reverse- connection protection |
Prevents failures due to wiring errors. |
| IP67: Leak-free head | The detecting surface is made with a metal housing of sealed monolithic structure. |
| Conical PressTM | It corresponds to the environment where water and oil adhere. |
| 3 models by output | Line driver / Semi-open collector [open collector + pull-up] / Differential (balanced) CMOS. |
| Detects other than gears | Magnetic materials with peaks and valleys [1-2 teeths, holes, etc.] |
