Magnetic sensors have been used for decades in versatile applications – from automotive to consumer, industrial automation, robotic, security systems, medical diagnostic equipment, and many other fields. They provide very reliable sensing capabilities and are well suited for harsh and dynamic environment applications. Solid state switches (or magnetic sensor Switch) are one very important type of magnetic sensors.One of the most popular solid state switches in the industry is HAL109JQ-I. This article discusses the application field and working principle of HAL109JQ-I.

HAL109JQ-I is a type of magnetic switch designed for use in cable tugging systems, such as unlocking devices, automatic locks, and other applications requiring high accuracy and reliability. It is the latest generation of solid state switches, providing low power consumption, high sensitivity, and a wide operating temperature range. HAL109JQ-I can also be used in automotive, medical, and consumer applications.

The working principle of HAL109JQ-I is based on the “Hall effect”, which is the phenomenon of an electric current flowing through a conductor in the presence of a magnetic field. In this case, when the switch is activated, a small magnetic field is created by the current flowing through the conductor, which in turn generates a weak electric field between the two opposite poles of the switch. This generates a small voltage proportional to the strength of the magnetic field, which is used to trigger the switch.

HAL109JQ-I offers different operating current ratings to accommodate different applications, ranging from 11mA to 19mA. This allows for a maximum current rating of up to 125 mA. HAL109JQ-I can also work with a wide range of supply voltages from 6 volts up to 36 volts. The switch has an open circuit voltage of 65mV/V, meaning that the internal impedance is low enough that the current flows freely when the switch is activated. In addition, the switch has a response time of less than 20 milliseconds.

In terms of performance, the switch has a wide operating temperature range from -40 to +85 °C. This makes it well suited for outdoor and industrial applications. It is also resistant to vibration, shock, and electromagnetic interference, making it suitable for use in mobile applications. Finally, the switch has been designed to be highly reliable and has a long product life, with a guaranteed life of up to 5 million cycles.

HAL109JQ-I is an ideal choice for a wide variety of applications, such as in automotive systems, industrial automation, medical instruments, security systems, home automation systems, and others. Its wide range of operating current ratings, low operating voltage requirements, wide operating temperature range, and high reliability make it the perfect choice for a variety of applications. With its performance and ease of use, it is no wonder that HAL109JQ-I is one of the most popular magnetic switches in the industry.
