Magnetic Sensors - Switches (Solid State) are widely used in industrial, medical, and aerospace applications for their reliable switching capabilities. The AH173-WG-7-A is one such example of a solid state switch. It is a programmable switching device designed for applications requiring precision, reliability, and low power consumption. This application note will discuss the AH173-WG-7-A\'s application field and working principle.

The AH173-WG-7-A is intended for use as an on/off switch in industrial, medical, and aerospace systems. Its main features include a simple connection of two wires, and an adjustable hysteresis voltage that allows the switch to be programmed to control the switching threshold. Also, its low power consumption and small form factor make it suitable for applications where space is limited.

The AH173-WG-7-A is based on Hall effect technology, which is a sensing technology used in many sensor types. This technology works by detecting changes in the intensity of a magnetic field. When a magnetic field is applied to the switch, it generates a signal that is proportional to the field intensity. This signal is then compared against a threshold voltage, and the switch is triggered when it exceeds this threshold. This switch is also capable of automatic reset, thus the switch remains in its steady-state position when the magnetic field is removed.

The AH173-WG-7-A has two main operating modes: switch-on and switch-off. In switch-on mode, the switch will be activated when the magnetic field reaches a certain level. This level is adjustable by using the on-board potentiometer. In switch-off mode, the switch will remain off until the magnetic field reaches a certain threshold, which is also adjustable. The switch is designed to be triggered with a low power consumption, which makes it an ideal choice for low power applications.

The AH173-WG-7-A provides a high level of reliability due to its robust construction and its ultra-low power operation. It is also designed to operate in a wide range of temperatures, which makes it suitable for various applications. The device is also resistant to electromagnetic interference, which means that it can be used in noisy industrial environments.

In summary, the AH173-WG-7-A is a reliable, low power, and robust Hall effect switch. It is suitable for applications that require reliable switching, precision, and low power consumption. Its adjustable hysteresis voltage and automatic reset make it an ideal choice for many industrial, medical, and aerospace applications. Its small form factor and low power operation allow it to be used in space-constrained environments, while its resistance to electromagnetic interference makes it well suited for industrial applications.
