The SR3G-A1 magnetic sensor is a positioning, proximity and speed measurement module designed to detect magnetic fields and convert them into electronic signals. It is ideal for sensing magnetic fields generated by permanent magnets, electromagnets and inductors. This versatile and accurate module is used in many applications, ranging from automotive to medical and industrial automation.

In automotive applications, the SR3G-A1 is used for sensing wheel speed and position. This module is specifically designed to detect the low frequency, high resolution signals generated by wheel speed sensors. The module can also be used in proximity and position sensing applications to detect the position of objects relative to a reference point, such as in automatic doors or safety systems where objects must be within a certain range. This module is also used in industrial automation, where it is used to detect the presence of metal objects in a given area.

One of SR3G-A1’s advantages is its ability to accurately detect and measure low level signals at high frequencies. The module can detect magnetic fields down to as low as 0.01 mT (milliTeslas) and can measure frequencies up to 2.5 MHz. This is possible due to its low-noise input circuit and high dynamic range. This allows the module to detect small changes in magnetic field strength without any distortions or interference.

The SR3G-A1 magnetic sensor module is a current-output type sensor, which means that it generates a voltage output proportional to the current it draws from the field. The module is suitable for both AC and DC magnetic fields, and has two output channels that can be configured for single- or dual-channel output. The module has a wide operating temperature range of -40 to +105°C, making it suitable for long-term operation in harsh environmental conditions.

The SR3G-A1 is designed to be easy to use and integrate into systems. It has a small form factor with dimensions of only 25x25x4.2 mm and a built-in two wire interface that can be connected directly to a microprocessor. The module is supplied with a power supply and mounting hardware, making installation and setup easy and hassle-free.

In conclusion, the SR3G-A1 magnetic sensor module is an ideal solution for a wide range of positioning, proximity and speed measurement applications. It is a reliable and cost-effective device that can provide accurate detection and measurement of magnetic fields. Its small form factor, wide operating temperature range and low power consumption make the module an excellent choice for many applications.
