Signal Relays, Up to 2 Amps, are a tool used in an electrical application to switch signals or currents. One of the most common signal relays is the 3SBH1165A2. This particular unit is designed to be used in applications that have an automotive contribution, but is an acceptable choice for many other industries; the 3SBH1165A2 consists of two relays, one normally open (NO) and one normally closed (NC) contact.

Application Field of the 3SBH1165A2

The 3SBH1165A2 is used in automotive applications where there is a need to switch between two or more electronic signals, or to control current loads. It is an ideal choice for applications such as engine control systems, fuel injection systems, ABS systems, power windows or door locks and transmission control systems. It is also suitable for general telecommunication applications, as well as for industrial, consumer and home electronics.

Some of the particular features that make this signal relay an ideal choice for automotive applications are its small form factor, low voltage drops, and low power consumption (3W).

Working Principle of the 3SBH1165A2

The 3SBH1165A2 consists of two relays within a single housing, each of which can be activated by an input signal. The two relays can be either normally open (NO) or normally closed (NC) depending upon the requirements of the application. When the input signal voltage reaches a specific threshold, one of the relays is activated, switching its contacts to make or break the connection between two wires, allowing or blocking current flow. The second relay is then flipped, sending the reverse signal to the other wire to complete the process.

The two relays within the 3SBH1165A2 can be operated independently or mutually switched using an external signal. This allows the user to switch between two or more outputs in a single cycle. The 3SBH1165A2 also allows for auto reset after a specific amount of time. This allows the current to flow only for a short duration, which is ideal in applications where it is undesirable for the current to be continually flowing.

Advantages of the 3SBH1165A2

The 3SBH1165A2 has many advantages that make it a great choice for signal relay applications. Its small form factor ensures that it will fit in most applications with minimal space constraints. The low voltage drops associated with the 3SBH1165A2 means that less energy will be wasted as heat, increasing the efficiency and lifespan of the device.

The 3SBH1165A2 has a low power consumption of only 3W, and its low contact resistance allows for high reliability when opening and closing. The 3SBH1165A2 also has a high endurance and a wide temperature range, making it suitable for many applications. Lastly, the 3SBH1165A2 is designed to be RoHS compliant and ISO certified.

Conclusion

The 3SBH1165A2 signal relay is a perfect choice for automotive applications where there is a need to switch between two or more electrical signals, or to control current loads. It has many advantages such as a small form factor, low voltage drops, low power consumption, and a high endurance and wide temperature range. It can be operated independently or mutually switched using an external signal, and can be used in general telecommunication applications, as well as for industrial, consumer and home electronics. With all of its features, the 3SBH1165A2 signal relay is an ideal solution for many applications.
