Magnetic sensors are widely used as switches or contactors to control or cut off a circuit, either manually or automatically, in a variety of electrical, industrial automation and robotic applications. Solid-state magnetic sensors, such as the AH1903-FA-7, are particularly well suited to these applications due to their robust construction and reliable sensing capabilities.

The AH1903-FA-7 is a multipole solid-state magnetic switch, consisting of a range of magnetic reed contacts housed within an epoxy encapsulated ABS housing. The AH1903-FA-7 is designed for use in limited-space environments, with an overall size of 25 × 11.5 cm, and is capable of sensing a range of magnetic fields up to 40 m Tesla. The device is IP67 rated, making it suitable for harsh and humid environments, and is rated to operate from -40° to +125°C. The AH1903-FA-7 has an impressive life expectancy of 1 million cycles and is ideal for use in safety circuits and to monitor the position of doors, windows, shutters, and any other user-operated device.

The operation of the AH1903-FA-7 is based on the principles of magnetoresistance, whereby a magnetic field changes the electrical resistance of a material. In the AH1903-FA-7, a small ferroelectric material is sandwiched between two electrodes. When exposed to a magnetic field, the material\'s resistance changes proportionally; this change in resistance is then detected by a sensing circuit. The switch is mounted on a printed circuit board that contains a sensing circuit and two output terminals. When the magnetic field changes, the switch is either closed or opened, depending on whether the circuit is activated or deactivated, respectively. With this design, the AH1903-FA-7 is capable of detecting a wide range of magnetic fields, and can be used as a reliable switch in applications where precise positioning or detection is required.

The AH1903-FA-7 is an ideal solution for a variety of applications, ranging from industrial automation and process control to automotive safety systems and robotics. Due to its small size and wide operating range, the AH1903-FA-7 can be integrated into a range of systems with minimal installation effort. Additionally, the device is rated for up to 1 million cycles, meaning it can provide long-term reliable operation without requiring frequent maintenance or repair. The attachment screws have anti-tamper protection, ensuring secure mounting and eliminating the risk of false triggers.

In summary, the AH1903-FA-7 is a reliable and versatile solid-state magnetic switch, able to provide reliable sensing in a range of applications. Its reliable operation, wide operating range and excellent durability make it an excellent choice for applications where accurate sensing or switching is required.
