Power Relays, Over 2 Amps: ADJH21112 Application Field and Working Principle

The ADJH21112 has been developed by Electronics Engineers in order to overcome the industry challenges of protection and power control for high current power applications. It is used for applications which require a high input current to be switched, with power control or protection from overloads. The ADJH21112 has a current rating of 2 Amps and is available in both DIN rail mount and open-style mount.

The ADJH21112 is suitable for safety and industrial automation applications in which current needs to be switched on and off to control motors, pumps, lighting and other high powered appliances. This relay has a long-lasting construction and is designed for high temperatures, making it ideal for use in tough industrial environments.

The ADJH21112 features a cadmium-free contact with high-level resistance to voltage spikes, overloads and mechanical shock or vibration that may be encountered in industrial settings. It features a wide operating temperature range, withstanding up to 85°C and -40°C of ambient temperature. The contact cycle life is over 10 million operations. The relay also has a dustproof and waterproof design, meeting IP67 rating.

In terms of its working principle, the ADJH21112 relies on a electromagnetic field to activate and deactivate the relay. When a voltage is supplied to the relay’s coil, an electromagnetic field is created which in turn causes the contact arm to move. When the voltage is removed, the contact arm is released and the contact opens. This process can be repeated multiple times.

The ADJH21112 is a highly reliable and durable relay and is suitable for a wide variety of applications in industrial settings. It offers protection against overloads, voltage spikes and shock/vibration, and is resistant to high temperatures and humid conditions. The design also features an extended contact life cycle, making it a excellent choice for reliable power control in industrial settings.
