Magnetic sensors based on switched solid state technology are increasingly becoming an important tool in the engineering community due to their durability, non-contacting operation, and wide range of applications. The HAL102JQ-I (hereafter referred to as ‘the device’) is one such magnetic sensor. In this article, we look at the device’s application field and working principle.

The device is a 2.5mm mid-high range sensing switch, which is designed to detect the presence of magnetic fields in a range of up to 2.5T, or 25mT. It is suitable for a wide range of applications including door interlocking, proximity sensors, Hall-effect sensors, and magnetic flow sensors. The device has a low power consumption of only 16mA, and is available in both 4-pin and 3-pin configurations.

The device’s input range for detection is 0.55 to 2.5T, with an effective distance of up to 25mm. It also has an adjustable sensitivity option, allowing users to select from a range of pre-defined detection levels. The device has a maximum switching voltage of 200V AC, and a maximum operating current of 1A.

The device works on the principle of Hall effect detection. This is done by using a semiconductor material such as a CdS- or GaN-based thin-film that is placed between two electrodes. When a magnetic field is applied, the electrons in the semiconductor material move in a direction that is perpendicular to the applied field. This creates a potential difference, known as the Hall voltage, across the electrodes. The device is able to use this Hall voltage to detect the presence of a magnetic field.

The device also has an integrated, adjustable pull-up resistor, which allows the user to adjust the required sensitivity level. This allows for a wider range of detection levels, meaning the device may be used in a variety of applications.

The device has a wide range of applications. It can be used in door interlock systems to detect when the door is opened, or in proximity sensors to detect the presence of a person or object in a certain area. It can also be used as a Hall-effect sensor to measure the strength of magnetic fields, and as a magnetic-flow sensor, using the Hall voltage to detect the flow of a liquid or gas. Finally, the device can be used in induction heating systems, as the Hall voltage can be used to measure the current of an induction coil.

In summary, the HAL102JQ-I is a 2.5mm mid-high range sensing switch, which is designed to detect the presence of magnetic fields in a range up to 2.5T. It has a low power consumption of 16mA, and is available in both 4-pin and 3-pin configurations. Its input range is 0.55 to 2.5T, and it has an adjustable sensitivity option. It works on the principle of Hall effect detection, using a semiconductor material to create a Hall voltage between two electrodes. The device has a wide range of applications, including door interlock systems, proximity sensors, Hall-effect sensors, magnetic-flow sensors, and induction heating systems.
