Signal Relays, Up to 2 Amps

3SBC1621A2 is a signal relay with up to 2 amps of current that can be brought and switched with minimal power consumption. It is a miniaturized switching element for applications where space, costs and power consumption are important characteristics. This relay is primarily designed for communication, control, motor switching, automated manufacturing, and other industrial applications.

Application Field

3SBC1621A2 can be used in many application fields, such as industrial and consumer switches, solenoids, motor controls, control circuits, and many other switching applications. It is suitable for applications where low-level switching of analog signals is required for low-power operation. Its wide switching voltage range, low overall power consumption, and small size make it ideal for installations when a switching element is required which requires minimal space and power.

Working Principle

3SBC1621A2 is a relay which uses magnetic induction to disengage its contacts. Magnetic induction is the process whereby an electric current flowing through a wire creates a magnetic field. This magnetic field, when oriented in a certain direction, affects the contacts of the relay and facilitates their contact separation. This allows the contacts to be switched on or off through an electrical signal.

The 3SBC1621A2 contains a coil which is energized when an appropriate electrical input signal is applied. This coil is surrounded by an electromagnet. An electromagnet is a wired coil surrounded by a magnetic core which becomes magnetized when a current passes through its coil. When this current is applied, the magnetic field created interacts with the armature, causing it to move and activate the contacts.

This relay contains several features that permit it to switch up to 2 amps of current. It is designed to operate at a wide variety of temperatures, ranging from -40°C to +105°C, and is suitable for both AC and DC applications. It is also equipped with a small on board protection circuit to protect from overloading or short-circuiting. The on-board protection circuit is designed to disconnect the primary coil should an over-current situation occur, ensuring that the contacts remain closed during normal operation.

Conclusion

The 3SBC1621A2 is a versatile signal relay suitable for a variety of industrial and consumer applications. It is a compact, low-power switching element that is suited to analog and low-power operation. Its wide switching voltage range, low power consumption, and small size make it an ideal complement for high-demand installations requiring minimal space and power.
