Magnetic sensors and switches play an important role in multiple electronic and electrical equipment. One magnetic sensor switch is the AH3391Q-SA-7 magnetic sensor switch developed by Avago Technologies. This magnetic sensor switch offers users a wide range of design and functionality, as well as excellent accuracy and reliability. It is specifically designed for automotive and industrial application which requires smart sensing, excellent performance, and low operating cost.

The AH3391Q-SA-7 magnetic sensor switch is a solid-state switch that uses Hall-effect technology to detect magnetic fields. Its solid-state design allows it to be used in environments with high temperature, pressure, vibration, and shock, while still delivering reliable performance. This makes it a great option for harsh environment applications such as in the automotive, industrial, marine, aerospace, and medical industries.

The magnetoresistive (MR) technology used in the AH3391Q-SA-7 is also known as the Anisotropic Magnetoresistance (AMR) technology, which is more accurate and sensitive than Hall-effect technology. It consists of two components: a large magnetoresistive element and a smaller pivot arm that opposes the magnetic field. When the pivot arm is in the presence of a magnetic field, the magnetoresistive element within the switch changes its resistance. This change in resistance is then used to provide a signal to indicate the presence of a magnetic field or the direction of the magnetic field.

The AH3391Q-SA-7 magnetic sensor switch features a maximum angular resolution of 3.7 degrees, and a maximum working temperature range of -40°C to 150°C. It is made with surface mount technology for easy installation and uses back-side protection to protect against ESD. It has a very low operating electrical power consumption and is extremely durable and reliable, making it a perfect choice for long-term operating applications. Plus, its high operating frequency makes it an ideal choice for applications requiring high accuracy, even in applications with high pressure and temperature.

The AH3391Q-SA-7 magnetic sensor switch is a flexible and reliable solution for a wide range of applications. It can be used for various purposes including sensing speed, direction, and orientation of moving objects, setting triggers for motion sensing security systems, and detecting the presence of metal objects. Additionally, it can be used in automotive applications like sensing engine RPM, monitoring exhaust gas temperature, and measuring pressure. It can also be used in industrial environments such as monitoring pressure and flow, controlling motion, and detecting the presence of magnetic objects.

The AH3391Q-SA-7 magnetic switch is an excellent choice for many applications that require reliable performance in harsh environments. Its unique combination of features make it the ideal choice for anyone who needs a dependable, cost-efficient solution for their magnetic sensing needs.
