ELF (Extended Low Frequency) Connectors are special backplane connectors that have been designed to transmit signals across the backplane of a computer system. These connectors are designed to help alleviate current signal interference by providing increased signal stability and reducing crosstalk between adjacent lines. ELF connectors are ideal for systems with multiple types of connections, such as those found in the embedded and industrial automation markets.

ELF Application Fields and Working Principle

The main application of ELF connectors is in applications where high signal stability and low crosstalk are necessary. This makes ELF connectors perfect for use in the industrial and embedded automation markets. ELF connectors are also widely used in computer networks, telecommunication, aerospace, and other applications where reliable data transmission is critical.

ELF connectors are based on a standard three-pin design. The two outer pins are the signal pins, and the center pin is a ground pin. All of these pins are exposed along the outside of the connector. The exposed pins make ELF connectors easy to connect and disconnect since no additional tools are required. They also help reduce crosstalk and signal noise interference, providing better signal stability between the pins.

The ELF connector is also referred to as an Extended Low Frequency connector because of its ability to transmit signals up to 50 kHz. These signals can be either analog or digital, although digital signals typically require more shielding to protect the signal from noise and crosstalk. ELF connectors also come with optional EMI/RFI (electromagnetic interference/radio frequency interference) shields that can filter out noise and improve signal integrity.

Aside from signal and noise interference, ELF connectors also help reduce resistance across the backplane. This is due to their low insertion force and large contact area. The low insertion force allows for easy installation and quick cable assembly. The large contact area also helps reduce resistance, which can help improve the signal integrity of the system.

ELF connectors are also highly reliable due to their unique design. Every ELF connector comes with a latch system that prevents the connector from being pulled out accidentally. This latch system ensures that the connection between the two pins remains secure. ELF connectors also boast a 95% contact reliability rate, making them one of the most reliable backplane connectors available.

To sum up, the Extended Low Frequency (ELF) connectors are special backplane connectors designed for high signal stability and low crosstalk. They offer an optional EMI/RFI shield and include a latch system to ensure a reliable connection. ELF connectors are ideal for applications in embedded and industrial automation markets, as well as computer networks, telecommunication, and aerospace systems.
