HE721A2415 Datasheet/PDFReed Relays
Reed relays are electro-magnetic switches which are used to control the flow of current or a flow of a gas. The relays are usually small mechanical components with very low power consumption, and they are ideal for applications where space is limited or the size of a circuit is important.
HE721A2415 Application Field and Working Principle
The HE721A2415 model of reed relays is a high-frequency, high-voltage relay with a long life expectancy, making it suitable for a variety of applications. The relay features insulated reed contact discs which are constructed from stainless steel and operate on a variety of switching voltages, including DC to AC, AC to DC, or both.
The working principle of the HE721A2415 relay is simple; when a voltage is applied to the coil, it generates a field which attracts the reed contact disc and causes the contacts to activate. To deactivate, the current is then released from the coil and the contact moves back to its original position.
The HE721A2415 model is most commonly used in automotive applications as an overload protection, and in industrial control systems for machine automation. The product can also be used as an alternative to electromechanical limit switches in agricultural applications and for pumping controls.
