DF3EA-4P-2V(51) has two-row, standard mounting connectors with independently mated contacts in each row. Each contact features 2mm pitch, and the male pin is gold plated. It has an operating temperature of -40 to 105°C and a standard lead-free housing material of UL94V-0.

The DF3EA-4P-2V(51) connector finds its main application in the automobile industry, continuous machinery, switches, controls, monitors, human-machine interface (HMI), and other vehicular and consumer electronics applications. This connector also offers high reliability and durability, making it ideal for use in medical and healthcare technology.

Working Principle

With the DF3EA-4P-2V(51), the electrical connection is provided by a pin-in-socket design for contact mating. The small pitch aids in improved signal integrity and offers higher packaging density. It is a 2mm pitch surface mount, and the connector has low electrical resistance allowing better heat conduction. In addition, the holder and locking device ensure proper mating strength and stability.

The secure locking system of the DF3EA-4P-2V(51) is provided by the locking latch/hook at the end of the connector. The locking system can be loosened/tightened by either direct downward pressure on the locking latch or by inserting a tool into the unlocking holes of the connector. This allows for secure locking on all applications.

Accurate and Reliable Contact Clamps

The DF3EA-4P-2V(51) connectors are designed with a high-precision contact clamp that enables them to maintain a reliable electrical connection with high-frequency signal applications. The contact clamp of the DF3EA-4P-2V(51) consists of two parts – a body and the male pin, which provide an accurate and reliable connection. The contact force on the connection is optimized to ensure quality signal connections for today’s near-zero insertion force applications. The contact clamp enables the DF3EA-4P-2V(51) connector to maintain a reliable electrical connections even while operating in high temperature and vibration environments.

Conclusion

DF3EA-4P-2V(51) is a reliable 2mm pitch surface mount electrical connector with male pin. It has low electrical resistance, high-precision contact clamps, and a secure locking system. It finds its main application in automotive and healthcare sectors, but it can also be used in various other applications due to its reliability and durability.
