Magnetic sensors are an important set of sensors used in industrial applications to provide accurate measurements of different properties, such as flux density or the presence of a magnet. The most common type of magnetic sensor is the switch, which operates by detecting the presence or absence of a magnetic field. The HAL202TQ-K is a magnetic switch from HPS (Haru Precision Systems), specially designed for industrial applications. It is used for monitoring the presence of a magnet in a specific location, making it ideal for use in safety-critical applications where the detection of a magnet indicates a hazardous condition.

The HAL202TQ-K sensor operates on the principle of the Hall effect, which states that the voltage generated across a conducting material placed in a magnetic field is proportional to the flux density of the field. The HAL202TQ-K has two Hall effect sensing elements, one positive and one negative, mounted in a planar package. The elements are connected to a comparator circuit, which compares the output of the two elements and triggers an output signal if the difference between them surpasses a certain threshold. The sensor is designed to be insensitive to environmental influences such as EMI, temperature changes and vibration, providing reliable operation in even the harshest industrial environments.

The HAL202TQ-K is designed for many different applications, from simple on/off control of an industrial machine to more complex sensing applications such as magnetic flow sensing, hydraulic pressure sensing and liquid level sensing. It is designed to be used in intrinsically safe systems, so it is impervious to sparks and other hazardous voltages. It can be powered by both AC and DC voltage sources and has a built-in hysteresis that eliminates false positives and ensures its reliable operation. The sensor is also designed to be simple to install and reliable over a long period, making it ideal for a wide range of industrial applications.

The HAL202TQ-K can be used to monitor the presence of a magnet in a particular location, or to detect changes in the strength of a magnetic field. When a magnet is present, the output of the sensor is triggered, signalling the presence of the magnet. This information can be used to control equipment, monitor the movement of a magnet or control the safety of a system. It can also be used in flow sensing, to detect the presence of a magnetic field and thus calculate the rate of flow.

The HAL202TQ-K is a versatile magnetic switch designed for use in industrial applications. It is easy to install and has low power consumption, making it ideal for applications that require a reliable and accurate magnetic sensing device. It is highly resistant to environmental influences and is designed to be used in intrinsically safe systems. The HAL202TQ-K is a reliable and accurate sensor, offering excellent performance for a wide variety of applications.
