Magnetic sensors are electronic switches that can detect the presence or absence of a magnetic field. Magnetic sensors are widely used in many applications including automotive, aerospace, and consumer electronics. The AH3781-P-A is a solid-state, Contactless, Magnetic Sensor Switch that is designed to provide excellent sensitivity, long-range detection, and high reliability.

The AH3781-P-A is an ideal sensing solution for applications such as proximity sensing, level sensing, and position sensing. It can detect ferrous materials, such as steel and iron, as well as non-ferrous materials, such as aluminum and brass. The AH3781-P-A can operate over a wide temperature range and is tolerant to shock, vibration, and environmental noise. The AH3781-P-A is ideal for applications that require reliable, contactless sensing with minimal installation time.

The AH3781-P-A is designed with a magneto resistive active element, which provides a highly sensitive and stable sensing element. Furthermore, the active element is housed in a stainless steel body to ensure high durability. The AH3781-P-A has an operating frequency range of up to 5 MHz, and it can detect magnetic fields over a distance of up to 50 mm. This makes the AH3781-P-A an ideal solution for applications that require long-range detection.

The AH3781-P-A also features overvoltage and overcurrent protection, as well as short-circuit protection. Additionally, the AH3781-P-A is designed to withstand up to 5KV Electro Static Discharge which makes it suitable for use in harsh and demanding environments. The hardware is also designed to protect against electro-magnetic interference.

The AH3781-P-A variant of the magnetic sensor switch works on the principle of field-effect conduction due to the inductive properties of a magnetic field. A magnetic field is generated around the active element of the switch when a ferrous metal, such as steel or iron, is brought near it. This field-effect causes a current to flow in the active element, generating an output signal. The strength of this output signal is proportional to the change in magnetic field detected by the active element.

The AH3781-P-A is a highly versatile magnetic sensor switch that can be used in a variety of applications. It is ideal for use in harsh industrial environments and can withstand shock, vibration, electro-magnetic interference, and adverse environmental conditions. The AH3781-P-A has a wide operating frequency range and can detect magnetic fields over a distance of up to 50 mm, making it an ideal solution for long-range detection.
