HAL211JQ-K Application Field and Working Principle

HAL211JQ-K is a magnetic solid state sensor manufactured by Panasonic. It is categorised under Magnetic Sensors-Switches (Solid State) and claims to offer various advantages due to its solid state design. These advantages are mostly related to the improved robustness and dependability of the sensor, enabling it to perform in extreme conditions and in harsh environments. The HAL211JQ-K is suitable for a wide range of applications in the industrial, automotive, medical and aerospace industries.

The working principle of the magnetic solid state sensor is based on the magneto-resistance effect. When a magnetic field passes through a Hall effect sensor, its resistance changes. This change is detected by the Hall-effect IC, giving an output voltage that is proportional to the magnetic field’s strength. This effect is known as the Hall voltage, and it allows the sensor to be used as a switch as well as a sensor.

The HAL211JQ-K magnetic sensor features a detection range of up to 20mT, which makes it suitable for applications such as detection of magnetic fields inside motors, detection of large mechanical stresses in permanent magnets and detection of materials inside pipes and containers. It also has good linearity of its output over a wide range of input measurements, and its hysteresis behaviour is such that its response is not impacted by small variations in the current applied. Additionally, it offers superior sensitivity due to its combination of solid state design and magneto-resistance technology.

The HAL211JQ-K is designed for surface mounting and comes in a Hermetically Sealed package which offers improved protection against dust, moisture and corrosion. Its metal housing also provides protection against electrostatic discharge and vibration. Additionally, the sensor is EMC compatible with low power consumption (<25μA) and a high sensitivity of up to 10mV, making it suitable for a wide range of applications.

Overall, the HAL211JQ-K magnetic solid state sensor is a reliable device that provides excellent performance in tough industrial environments. It offers superior sensitivity to magnetic fields with low power consumption and reliable operation in extreme conditions, making it suitable for a wide range of applications. Its hermetically sealed package and robust design also make it an ideal choice for various automotive, medical and aerospace applications.
