Reed Relays

Reed relays are switches that use an electromagnetic field to open or close an electric circuit. They use an armature that is actuator through an electromagnetic field in order to make contact between two wires or two circuits. They are normally used in applications that require low power switching from around 10′s of milliamps up to around 10′s of amps. They are used in a variety of industries from automotive to the consumer electronics market and come in a wide range of sizes; from those small enough to fit on a printed circuit board up to larger units for wired systems.

A reed relay, model HE3621A2400, is a hermetically sealed device that has high switching speed and low loss. It uses low power and features high immunity to vibration, shock and temperature stress. It is typically used in automotive, industrial and medical applications.

Application Field

The HE3621A2400 relay is used in a wide variety of applications where low power, high vibration, and temperature resistance are required, such as automotive, industrial, and medical. For example, it can be used for controlling a light circuit in a car, switching circuits in a production line, or powering a medical device. It is also often used in combination with higher power components, such as solenoid valves and motors, to provide control over the operation of these components.

Working Principle

The HE3621A2400 uses a hermetically sealed design. The hermetically sealed design allows for a less susceptible design to heat, vibration and dust, making it suitable for more extreme conditions. The device consists of an actuating armature, which is actuated by an electromagnetic field when energized. This activates an internal switch, allowing it to make contact between two wires or circuits. When the armature is pulled down, the contacts close, and when it is released, the contacts open. The contacts are shielded by a stainless steel can which increases its durability. The high speed of switching, along with its low power consumption, make it ideal for applications where fast switching rates and low power requirements are required.

The HE3621A2400 is a reliable, low loss, hermetically sealed relay that provides high switching speed and low loss. It can be used for low current applications, where low power requirements and high immunity to shock and vibration are of main importance.
