Magnetic sensors switches (solid state) are an important component in many industries, from autonomous cars to consumer electronics. The HAL103JQ-I is an omni-directional magnetic switch which uses hall effect technology to detect the presence of metal near the switch. By using hall effect technology, the HAL103JQ-I is reliable, accurate, and cost effective for a wide range of applications.

The HAL103JQ-I is a solid statehall effect switch which relies upon the principle of hall effect to detect the presence of metal in its vicinity. Hall effect is a phenomenon in which the presence of a magnetic field causes a voltage to be generated in the sensing material of a Hall element. In the case of the HAL103JQ-I, the sensing material is a thin film of low-temperature coefficient iron (Fe). This iron is applied to the top and bottom of the switch by a temperature-sensitive process which ensures that the switch is kept perfectly aligned.

The HAL103JQ-I detect the presence of metal by measuring the hall voltage generated using four poles around the perimeter of the switch. Each pole will sense the presence of a magnet in its vicinity. If the voltage generated at any of the sensor poles exceeds a pre-set threshold, this is interpreted by the switch as the presence of metal and triggers an output signal.

This output signal can be used to control various functions. For instance, in autonomous vehicles, the HAL103JQ-I can be used to detect the presence of nearby objects such as other vehicles, obstacles, and pedestrians. This allows the vehicle to avoid collisions and functions like parking assistance where the vehicle will automatically park itself without any input from the driver. In consumer electronics, HAL103JQ-I can be used to help devices detect when they are near magnetic objects, such as headphones or a docking station, and activate certain functions. For example, when a pair of headphones is near a media player, the HAL103JQ-I can be used to detect this and trigger the device to start playing music.

The HAL103JQ-I offers high reliability with a long lifespan of up to 100 million operations. This makes it suitable for a range of applications in industrial, consumer, automotive, and medical industries. The switch has an operating temperature range of -20° to 75°C and a sensing range of 0.3 to 2.0T. It is also compatible with a variety of materials, from ferromagnetic to non-magnetic metals.

The HAL103JQ-I is a cost-effective hall-effect switch suitable for detecting and controlling a wide variety of magnetic components. Its omni-directional sensing capability allows it to detect metal near the switch, making it an ideal choice for applications in the automotive and consumer electronics industries.
