What are the Advantages of the Hall Switch Over the Reed Switch?

Sep. 22, 2020

As a Latch Type Hall Sensor Factory, share with you. Before the development of solid-state Hall sensors, magnetically actuated reed switches have been widely used for decades, providing a tried-and-tested and inexpensive solution for position sensing. With the development of Hall-effect technology, Hall-effect sensors have begun to replace reed switches in some battery-powered applications, such as mobile phones, notebooks, consumer electronics and white goods.

For design engineers who use Hall switch alternatives to reduce switch size, improve switch quality and durability, and maximize battery life, the new Hall switch technology can provide them with uA switching power consumption while also having The characteristics of high sensitivity, and the cost performance is better than the reed switch.

ReedSwitch, also called reed switch or reed switch, is a magnetically sensitive special switch. It was invented by Walter B. Ellwood of Bell Telephone Laboratories in 1936. He himself had applied for a patent in the United States in 1940. In the following decades, the reed switch has been widely used in the industry and has gradually become a cost-effective magnetic position switch sensor.

The Hall switch sensor is a high-sensitivity, high-frequency response, ultra-low power consumption and high-precision magnetic induction switch. It integrates and uses high-precision push-pull magnetic sensors and CMOS integrated circuits, which can convert changing magnetic field signals into digital voltages. Signal output.

The Hall switch sensor provides temperature compensation power through an internal voltage regulator, and allows a wide operating voltage range. There are many types of Hall switches: low voltage operation, extremely high response frequency, microampere power supply current, wide operating temperature range and high ESD withstand voltage, making them ideal for many switch applications.

With the continuous advancement of technology, Hall switch technology has been well commercialized, and reed switches are no longer the only choice for magnetic switches. For design engineers looking for alternatives to reed switches to increase switch sensitivity, reduce switch size, improve switch quality and durability, and maximize battery life, the new Hall effect technology can provide them with uA switching power consumption , At the same time, it has the characteristics of high sensitivity and higher cost performance.
