70430-161LF Connectors, Interconnects

Connectors are used to link two or more circuits together, and backplane connectors are a specific type of connector used to link printed circuit boards within an electronic chassis. Their key characteristics include speed, density, signal quality and cost effectiveness. The 70430-161LF, manufactured by Molex, is an example of a specialized backplane connector that has specific features designed for use in a certain application and with a specific working principle.

The 70430-161LF is designed for use in industrial automation, LPWAN, Power over Ethernet (PoE), and automotive applications. It is compliant with IEEE 802.3at, EN 62443, NFPA 79, and industrial automation standards. Its small size and rugged design make it well suited to small and isolated power distribution systems. The connector measures 11mm in length and 4.4mm in width and requires a mating force of 4.5N.

The 70430-161LF features two power pins and four signal pins that support up to 8 Gbps signaling rates. The power pins are spaced further apart than the signal pins, which provides galvanic isolation of up to 950V RMS and a minimum of 25V for reliable data transmission. The connector also has a specially designed dielectric material and gold plated contacts to ensure high-strength connections and low contact resistance. The contacts are also designed to prevent slipping out during mating, and the connector is password protected to minimize insertion faults.

The 70430-161LF features a mating interface that allows for up to 5 insertion/extraction cycles, making it highly reliable and robust. The connector also has an internal double wall insulation system that protects against short circuits and increases mechanical strength and durability. The connector is also RoHS compliant and resistant to vibration and shock, making it suitable for many industrial applications.

The 70430-161LF works on the principle of differential signal transmission. Differential signals transmit two complementary signals and use a pair of conductor wires to deliver an analog voltage between ground and a reference voltage. This type of signal transmission is less susceptible to electromagnetic interference and provides more reliable connections than traditional single-ended signal transmission. Furthermore, this differential signal transmission is capable of providing faster data transfer rates and longer transmission distances.

The 70430-161LF is a specialized backplane connector that is designed for use in specific applications. Its small size, high signal integrity, and robust material make it a viable choice for industrial automation, LPWAN, PoE, and automotive applications. With its differential signal transmission, the 70430-161LF provides reliable connections with faster data transmission rates, longer transmission distances, and better protection against electromagnetic interference.
