Magnetic Sensors - Switches are electromechanical components used to detect the presence or absence of a magnetic field. AH173-WL-7-A is a type of magnetic switch which are used in various applications to provide contact-less operation of equipment with quick and accurate response time. These switches are best used for applications which require both low consumption and long battery life.

The AH173-WL-7-A magnetic switch consists of three main parts: a reed switch, a magnet, and a PCB (printed circuit board). The reed switch is a glass tube which contains a pair of contacts that are sealed in a vacuum. When a magnet is brought close to the reed switch, the contacts inside of the glass tube are drawn together, forming a closed circuit. This closed circuit is then used to power the PCB.

The application of the AH173-WL-7-A magnetic switch is varied, ranging from automatic door openers and water tank level sensors to industrial machinery automation and security systems. In the fields of industrial automation, the switch is used to detect the presence of certain objects or materials and to trigger automated processes accordingly. In door openers and security systems, the switch is used to detect the presence of an authorised object that will unlock the door or turn on the alarm system. It can be used in water tank sensors to detect the level of water in the tank and turn off the motor automatically when it reaches a predetermined level.

In terms of working principle, the AH173-WL-7-A magnetic switch operates in two states—a normally-open state and a normally-closed state. In the normally-open state, the reed switch is open and no power is supplied to the PCB. When the magnet is brought close to the reed switch, the contacts inside the glass tube close, allowing power to flow through the switch and to the PCB. In the normally-closed state, the reed switch is already closed before the magnet is brought close. When the magnet is brought close to the switch, the contacts open, breaking the circuit and preventing power from flowing through the switch.

The AH173-WL-7-A magnetic switch is a versatile and reliable electromechanical device. Its multiple application fields, long battery life, and low consumption make it an ideal choice for applications that require contact-less operation with accurate response. In addition, its two-state working principle gives it the versatility to be used in a variety of scenarios, such as door openers, water tank sensors, and industrial machinery automation. With its robust design and reliable performance, the AH173-WL-7-A magnetic switch is an excellent choice for any application requiring a contact-less system with quick and accurate response.
