The 71991-404LF connector is a rectangular connector commonly used in industrial applications. It is designed to provide a reliable electrical connection that can withstand high temperatures and is ideal for use in networking and communication systems. The connector comprises of two separate components – a male header and a female receptacle socket. The header is typically mounted on the surface of the PCB board and the female socket is mounted on the wire or cable. The two components then mate to provide a secure connection.

The 71991-404LF connector is a versatile and robust electrical connector that offers excellent performance in a variety of applications. It has a maximum current rating of 3A and a maximum voltage of 250VAC. The connector features a latch lock mechanism that provides additional connections security and prevents accidental disconnection. It also has a high dielectric strength, making it suitable for use in applications where signal integrity is critical. The connector is designed for quick and easy assembly and is made from tin-plated anodized copper and brass which provides superior performance and corrosion resistance.

The 71991-404LF connector has several key features that make it suitable for use in a wide range of applications. Its high current rating and voltage range makes it suitable for use in high-power applications such as power supplies, motors and lighting control systems. The high dielectric strength of the connector offers excellent protection from electrical disturbances such as noise and Electro Magnetic Interference (EMI). The latch lock mechanism ensures that connections remain secure while the connector is subject to shock and vibration.

The 71991-404LF connector’s working principle is relatively simple. The two components – the male header and the female receptacle socket – mate to form a secure electrical connection. The connection is made first by positioning the male header into the female socket. This action compresses the two components together, forming a tight seal. The latch lock mechanism is then engaged to ensure that the connection remains secure while in use.

In summary, the 71991-404LF connector is an ideal choice for industrial, networking and communication applications. It is designed to provide a secure, reliable connection that can withstand high temperatures and is easy to assemble. The connector’s high current rating and voltage range make it suitable for use in a wide variety of applications while the latch lock mechanism ensures additional connections security. The connector is also resistant to corrosion and provides excellent protection from electrical disturbances such as noise and EMI.
