This section introduces rotation sensors that detect various rotational speeds, such as wheels, transmissions, and engines.
Magneto-electric conversion elements, mainly Hall ICs, are packaged using a proprietary method to achieve compactness,
high precision, and high reliability.
It has been used in automobiles, motorcycles, agricultural machinery, ships, etc., and has been mass-produced for more than 30 years.
High vibration resistance by molding the internal circuit, and high versatility for mounting with a cord type.
We also have a lineup of timing detection sensors that can be used to detect engine ignition timing, and phase difference output specifications that can detect the direction of rotation.
Our sensor uses the internal calibration function to output stable pulses even if there are variations in the installation environment such as gap variations.
Features | TYPE name |
direct connector type | GT-1S direct connector |
cord pull-out type High vibration resistance (50G or more) |
GT-1S |
Timing detectable type | GT-1T |
Rotation direction detectable type | GT-1D |
Extremely low speed rotation detectable type |
GT-2/GT-4 |
The sensor detects the strength of the magnetic force that changes with the movement of the magnetic material and outputs the corresponding pulse.
【GT-1S direct connector】
[Application Example]Revolution speed detection sensor
It is a non-contact sensor that detects unevenness of the transmission gear.Output waveform of this sensor is a square wave.
【GT-1S】
[Application Example]Revolution speed detection sensor
Various connector and harness types can be selected, and it has high attaching adaptability and high vibration resistance (50G or more).
【GT-1T】
[Application Example]Crank angle sensor, Cam angle sensor
It is a timing detection sensor that detects the ignition timing of the engine. Connector type and cord type is available.
【GT-1D】
[Application Example]Revolution direction detection sensor
It is a revolution sensor that detects rotation speed and direction with one sensor. Output type: 2phase pulse output.
【GT-2/GT-4】
[Application Example]Revolution direction detection sensor
It is a sensor that can detect extremely low speed rotation compared to GT-1S series.The output is a square wave, and the sensor shape can be changed.
【GT-3】
[Application Example]ABS revolution sensor
It is a two-wire revolution sensor that outputs the current value.
Since the cord part and the detection part are manufactured integrally, it is small and lightweight.
In addition, since the detectable gap is wide and it can be detected even at extremely low speeds, it is highly versatile for mounting on an actual vehicle.
The sensor detects the strength of the magnetic force that changes with the movement of the magnetic material and outputs the corresponding pulse.
Basically, it is output as a current change, By connecting a resistor to the GND line of the sensor as shown in the figure below, it is also possible to detect the output pulse as a voltage change.
