Magnetic sensors are a type of sensor that can detect the presence of a magnetic field or the magnitude of an external magnet. Magnetic switches, or solid state switches, are a specialized type of magnetic sensor that provide output when a magnetic field is detected, and typically have no moving parts. One such magnetic switch is the AH173-PG-A-B, which offers a variety of features that make it well-suited for a variety of applications and working conditions.The AH173-PG-A-B is a small, low-cost, single-pole, single-throw (SPST) reed switch that reacts to changes in the presence and strength of a magnetic field. The switch can be used with a variety of different magnets, including permanent and electromagnets. The construction of the switch is hermetically sealed and 100% welded, ensuring superior protection from environmental damage. Additionally, the switch itself is designed to be very small with a body size measuring only 0.30 x 0.48 x 0.67 inches (7.6 x 12.2 x 17 mm). This makes it an excellent choice for applications with limited space or weight restrictions.The AH173-PG-A-B is able to operate in a wide range of temperatures, from -40°C to 125°C (-40°F to 257°F), allowing it to be used in a variety of environments. Additionally, the switch offers a long life, with a mechanical life of over 10 million life cycles, and an electrical life of up to 1000 life cycles. This makes it an excellent choice for applications where long-term reliability and dependability is needed.The working principles of the AH173-PG-A-B magnetic switch are relatively straightforward. When the switch is in an open position, it allows current to flow from one end of the switch to the other. However, when the switch is in a closed position, current is prevented from flowing. This is due to the unique design of the AH173-PG-A-B, which features a mechanical reed switch that is triggered when a magnetic field is detected. When a certain level of magnetic field is reached, the reed mechanism triggers the switch to change from an open to a closed position, or vice versa. This allows the switch to provide an output signal, such as an alarm, indicator, or other form of feedback, that can indicate the presence of a magnetic field.Due to its features and specifications, the AH173-PG-A-B magnetic switch can be used in a variety of applications requiring the detection of a magnetic field. For example, the switch can be used as part of a security system, to detect the presence of a certain magnetic field and trigger an alarm. Additionally, it can also be used as part of a home automation system, to detect the presence of a magnet in a certain area and control lighting or appliance settings automatically. It can also be used in industrial applications such as motor control or pressure monitoring systems.Overall, the AH173-PG-A-B magnetic switch is a highly reliable and effective device for detecting the presence or strength of a magnetic field. The switch is designed with a hermetically sealed construction and a wide range of operating temperatures, making it an excellent choice for applications requiring long-term reliability or environmental protection. Additionally, its small size makes it suitable for applications with size or weight restrictions. Furthermore, the simple working principles of the AH173-PG-A-B make it easy to use and integrate into a variety of applications requiring the detection of a magnetic field.
