Magnetic sensors and switches are components used for detecting the presence or absence of a magnetic field. The A3423EK-T is a miniature vertical reed switch that is a type of magnetic sensor or switch. It is a reliable and cost-effective solid-state magnetic switch designed for a variety of applications.

The A3423EK-T is an open-frame, solid-state switch with a miniature vertical package size of 13.2 mm x 9.5 mm x 2.3 mm. The vertical reed switch is designed with two hermetically sealed contacts which are isolated from each other. The contacts are made from high-grade gold plated phosphor bronze and the switch is resistant to moisture and vibration.

The primary purpose of the A3423EK-T is to detect the presence or absence of a magnetic field. It is an ideal device for applications where both low power consumption and low noise requirements are needed. It operates on a very low power of 5.5 mW and has a low operating voltage of 4.0Vdc. It also has a very low contact resistance of 0.1 ohms and a contact life of 30,000 cycles.

The switch can be used in a variety of applications, including automotive, HVAC, and security systems. It is often used as a switch in vehicle immobilization systems and alarms, where the switch is activated when a vehicle passes by a magnet. Additionally, the switch can be used in access control systems to control the electronic locks and entry systems. It can also be used as a motion sensor to detect motion or vibration, such as in a vehicle door or window.

The working principle of the A3423EK-T is based on its sensitive magnetoresistive material. When a magnet is in close proximity to the switch, its magnetic field activates the internal switch and closes the contacts, allowing electricity to flow between them. The switch remains closed and electricity is allowed to flow until the magnetic field is removed from the switch, at which point the contacts open.

In conclusion, the A3423EK-T is a miniature vertical reed switch that is a type of magnetic sensor or switch. It is designed to detect the presence or absence of a magnetic field and is ideal for applications where low power consumption and low noise requirements are needed. It has a variety of applications including automotive, HVAC, and security systems and its working principle is based on its sensitive magnetoresistive material.
