PR9376/010-011 Hall Effect Speed/Proximity Sensor

The PR9376/010-011 Hall Effect speed/proximity sensor is a sensor that works on the principle of the Hall effect and is mainly used to measure the speed of rotating objects (such as shafts or gears) or detect the proximity of objects.

The sensor has a differential sensor head consisting of a half-bridge having two Hall effect sensor elements. Hall effect sensors use the Hall effect principle, which is that when an electric current passes through a conductor located in a magnetic field, an electric potential difference is created on one side of the conductor.

Essential details：PR9376/010-011 Hall Effect Speed/Proximity Sensor

The PR9376/010-011 Hall Effect speed/proximity sensor is a sensor that works on the principle of the Hall effect and is mainly used to measure the speed of rotating objects (such as shafts or gears) or detect the proximity of objects.

The sensor has a differential sensor head consisting of a half-bridge having two Hall effect sensor elements. Hall effect sensors use the Hall effect principle, which is that when an electric current passes through a conductor located in a magnetic field, an electric potential difference is created on one side of the conductor. With an integrated operational amplifier, the Hall voltage is amplified several times and processed digitally in a DSP (digital signal processor). The DSP determines the difference in the Hall voltage and compares it to a reference value, resulting in a measurement of speed or proximity.

The advantages of the sensor include high resolution, high stability and low temperature drift characteristics, allowing it to output a stable waveform at low speeds. Its wide measurement range is suitable for a variety of application scenarios. In addition, the sensor has an anti-short circuit push-pull output, which protects the circuit from short circuit damage.

The PR9376/010-011 Hall effect speed/proximity sensor is usually used in conjunction with the velocity measurement gear disk, which is triggered by the rotation of the gear disk and produces the corresponding output signal. This kind of sensor has a wide range of applications in industrial automation, mechanical equipment, automobile manufacturing and other fields, for monitoring and controlling the running state of various rotating equipment.

PR9376/010-011 Hall Effect Speed/Proximity Sensor

Hall effect Speed/proximity sensors work primarily on the Hall effect, which is that when an electric current passes through a conductor located in a magnetic field, it creates an electric potential difference on one side of the conductor. This effect is widely used in fields such as magnetic field measurement and sensor manufacturing.

In a Hall-effect speed/proximity sensor, the sensor contains one or more Hall elements. When an external magnetic field (such as a magnetic field generated by a rotating or approaching object) acts on a Hall element, the Hall element detects this magnetic field change and generates the corresponding potential difference.

For speed measurement, the sensor is usually used in conjunction with the speed measurement gear disk. When the tooth rotates, the tooth and clearance on it will pass through the sensor in turn. Whenever a tooth passes by, the magnetic field changes, triggering the Hall element to produce an electrical signal. By measuring the frequency and phase of these signals, the rotation speed of the gear disk can be determined, and the motion speed of the object can be obtained.

For proximity detection, the sensor detects the proximity of external objects, such as metal objects. When the object is near the sensor, the magnetic field generated by it acts on the Hall element, causing a change in the potential difference. By detecting this change, the sensor can determine whether the object is close and output the corresponding signal.

In a Hall effect speed/proximity sensor, the output signal is usually processed and amplified by an internal circuit to provide more stable and accurate measurement results. These signals can be used in many applications such as speed monitoring, position detection and object counting in control systems.

In general, the Hall effect velocity/proximity sensor can measure the speed or proximity of an object by using the Hall effect to detect changes in the magnetic field. This kind of sensor has high precision, high stability and reliability, and is widely used in industrial automation, mechanical equipment, automobile manufacturing and other fields.
