Automotive relays are one of the most commonly used switching components in automotive electrical engineering. From the human-machine interface to the simple circuit connection, they can be used to perform switching or connection tasks. The CB1AH-R-12V relay is a normally closed type relay, which can open or close contacts with the change of coil current, and has the characteristics of strong power, wide range of applications and high reliability. This article focuses on the application field and working principle of CB1AHR-12V.

Application Field

The CB1AH-R-12V relay is generally used in 12V automotive electrical systems. It is usually used for remote control, voltage and current protection, and signal level conversion. Specific applications include:

• Open or close various circuits in automotive electrical system, such as AC system, light system and instrument system.
• Providing switching functions to control engines, transmission, and other groups.
• Perform voltage and current protection functions, such as providing over-temperature protection to electrical systems.
• Power relays for controlling power start and disconnection.
• Other remote control and signal conversion.

In addition to these common applications, the CB1AH-R-12V relay can also be used in power redistribution and other complex electrical systems, and even applied in elevators, robots, and other automation applications.

Working Principle

The CB1AH-R-12V relay consists of a coil, a set of contacts and an armature. When the coil is not energized, the armature is attracted to the contact set by the spring force , and the contact remains in the normally closed state. When the coil is energized, the armature is attracted by the electromagnetic force. As the armature moves away from the contact set, the contacts are opened or closed depending on the orientation of the contact set.

The CB1AH-R-12V mainly uses electromagnetic force to actuate the armature, while the opening and closing of the switch is mostly achieved by upper and lower spring patches. The user can adjust the power distribution of the coil to affect the speed and reliability of the opening and closing of the switch. This ensures a reliable connection when the switch is opened or closed.

Conclusion

The CB1AH-R-12V relay can provide high-reliability switching functions for the 12V automotive electrical system. It has a wide range of applications, including remote control, voltage and current protection, power restart and disconnection, and other signal conversion. Automotive electrical systems generally use relays to switch entire circuits, and the CB1AH-R-12V relay has the integrated advantages of electromagnetic force, upper and lower spring patches, which can provide reliable and fast switching function for the circuits.
