Rectangular Connectors: Headers, Male Pins, 77311-427-35LF Application Field and Working Principle

Rectangular connectors are a type of unshielded electrical connector typically employed for low voltage, low current circuits. These connectors use two sizes of pins, with the larger ones used for power and the smaller ones for signal lines. The 77311-427-35LF connector is a header-style rectangular connector that is configured with two rows of male pins, each with a pin spacing of 0.050 inch. It is commonly used for PCB (Printed Circuit Board) applications such as in the aerospace, automotive, military, and telecommunications industries. This article will discuss the application field and working principle of 77311-427-35LF connectors.

Application Field

77311-427-35LF connectors are typically used for military and aerospace applications, such as in the guidance, navigation, and control systems. These connectors also feature an IP67 waterproof rating, which makes them suitable for use in wet environments. In addition, they have a high vibration resistance, making them suitable for harsh environmental conditions. The pins are gold plated for excellent electrical conductivity and corrosion resistance, making the 77311-427-35LF connector suitable for high-reliability applications.

The 77311-427-35LF connector is designed to be used in multi-row applications. It uses an automated wave soldering process for improved soldering of the pins. The connector\'s low-profile design allows it to fit in tightly-packed applications. The body is made from UL94V-0 rated black thermoplastic, which provides excellent electrical insulation. The contacts are made of high-grade copper alloy for enhanced electrical performance. In addition, the connector is fully RoHS compliant.

Working Principle

The 77311-427-35LF connector is designed to provide a secure and reliable electrical connection between two points. It consists of two rows of pin contacts, each with a 0.050 inch (1.27 mm) pin spacing. To install a 77311-427-35LF connector, the pins must be inserted into a compatible mating part or printed circuit board. Once the pins are inserted, they will make contact with the corresponding contacts in the mating part. The contacts are held securely in place by a spring-loaded, two-piece housing.

The 77311-427-35LF connector is designed to withstand current up to 11A. It is also designed to provide a low contact resistance of 0.010 Ohm. The connectors have an operating temperature range of -55°C to +125°C and are rated for 200 mating cycles. In addition, the housing is designed to provide EMI/RFI shielding, which prevents the transmission of interfering noise from the device.

Conclusion

The 77311-427-35LF connector is a header-style rectangular connector that is configured with two rows of male pins. It is commonly used for military and aerospace applications, such as in the guidance, navigation, and control systems. The connector has a low contact resistance of 0.010 Ohm and a current rating of 11A. It is designed to operate in a temperature range of -55°C to +125°C and is rated for 200 mating cycles. The connector is also RoHS compliant and provides EMI/RFI shielding for maximum performance.
