Magnetic sensors and switches, commonly known as reed switches, are devices that use the magnetic field of a magnet to trigger a switch action. The AH375-WG-7 is a magnetic sensor switch manufactured by ACT. It is an electrical switch which uses a Hall Effect IC and can detect the presence, proximity, and magnitude of the magnetic field of a magnet.

The AH375-WG-7 is used in applications such as door open and close detection, security systems, motor speed sensing, and people counting systems. It is reliable and affordable, ensuring greater ease of use and accuracy in detecting the presence, proximity, and magnitude of the magnetic field of a magnet. The switch is made of stainless steel, and it features a wide operating temperature range with low electrical consumption and no data drift for extended periods of time.

The AH375-WG-7 operates on the principle of Hall Effect. Hall Effect is a process that occurs when a voltage is applied to the side of a conductor in the presence of a magnetic field. This voltage creates a current proportional to the magnitude of the applied magnetic field in the conductor, which in turn activates a circuit. This is the basis of the AH375-WG-7’s functioning as a magnetic sensor switch.

The AH375-WG-7 is designed with an array of Hall Effect ICs and is connected to a control circuit, which activate a switch action. The array of Hall Effect ICs is made of four small Hall Sensor ICs arranged in a cross pattern, with each one detecting the presence, proximity, and magnitude of the magnetic field in different directions. With the help of these Hall Sensor ICs, the control circuit is able to detect any anomalies in the presence, proximity, and magnitude of the magnetic field, thereby triggering the switch action.

As the array of Hall Effect ICs are arranged in a cross pattern and situated in four different directions, the AH375-WG-7 has a much higher sensitivity than regular sensor switches. Moreover, the device is highly resistant to EMI and environment conditions, making it a suitable solution for applications where reliability and accuracy are of paramount importance.

The AH375-WG-7 has several features, such as analog output or PWM output, adjustable supply voltage, over-current and low voltage protection, and wide operating temperature range. In addition to these features, the device also offers several advantages, such as low power consumption, programmable thresholds, galvanic isolation from the circuit, and high resistance to environmental and EMI interference. These features make the device ideal for applications where accuracy and reliability are important.

In conclusion, the AH375-WG-7 is a reliable and accurate magnetic sensor switch manufactured by ACT. It operates on the principle of Hall Effect and has several features, including analog/PWM output, adjustable supply voltage, over-current and low voltage protection, and wide operating temperature range, which make it suitable for applications where reliability and accuracy are of paramount importance. Moreover, the device has a higher sensitivity than regular sensor switches, making it a preferred choice for applications involving the detection of the presence, proximity, and magnitude of the magnetic field of a magnet.
