Magnetic sensors are used in a wide variety of applications, including intruder detection and security, industrial automation, aircraft navigation, robotics, and automotive systems. The most common type of magnetic sensors are solid state switches, which are designed to detect and activate with an applied force of a specific magnitude. The HAL 109JQ-C magnetic switch is a miniature, high-performance solid state switch, ideal for use in many of these demanding applications.

The HAL 109JQ-C utilizes a patented contactless design to detect an applied magnetic field, and then respond with a high-voltage, high-current signal. The detector element consists of two overlapping and magnetically coupled excitation coils and a sensitive Hall-effect element, which is capable of detecting a magnetic field of just 5 milligauss.

In operation, the excitation coils generate a sensing field of an adjustable strength, which is generally set to the minimum required to generate a sufficient response. When a magnetic field that exceeds the minimum excitation level is applied to the detector element, the Hall-effect element generates a signal in response. This signal is then amplified and then sent to the switching device, which responds with an on/off signal as appropriate.

The HAL 109JQ-C is designed to handle a wide range of temperatures, operating from -20°C to 135°C, making it ideal for use in extreme environments. The device also has a low power consumption, and is capable of operating on supply voltages ranging from 3.3V to 25V. Additionally, the switch can be operated in either normally open or normally closed mode, allowing for flexibility in application.

The HAL 109JQ-C can be configured to respond to a variety of different sensing fields, including sinusoidal and pulsed alternating magnetic fields as well as direct currents. This provides the user with the flexibility to tailor the device to their specific application, and ensure that it is responding accurately and reliably.

The HAL 109JQ-C is also designed with a built-in temperature compensation feature. This feature allows the switch to automatically adjust its detection threshold depending on the ambient temperature, thus providing more reliable switching without the need for user intervention.

Overall, the HAL 109JQ-C is an excellent choice for a wide variety of applications requiring a reliable, solid-state magnetic switch. Its combination of high performance, flexibility and low power consumption make it an ideal choice for demanding applications.
