Introduction

77313-120-30LF is a rectangular connector – headers, male pins specially designed for different application fields. This type of connector comes with a wide range of features and is generally used in a variety of applications requiring interconnection solutions such as computer systems, aircraft and industrial environments. In this article, we will discuss in detail, the application field and working principle of this particular type of connector, as well as related industrial standards and mode of installation.

Application Field

77313-120-30LF is primarily used in board-level interconnections. These are ideal for applications that require high-speed data transfer, high-density applications, and acceptance of both inline and horizontal card cage configurations. Due to its design and size, this type of rectangular connector can be used in a wide range of applications that need high-speed transmission and data communication such as computer systems, telecommunication systems, aerospace systems, and industrial control systems. The connectors are quite popular for use in power supplies and switchblade interconnections, networking infrastructure, LANs, and WANs.

Working Principle

The working principle of 77313-120-30LF is quite simple. Its male pins feature a tribocontact-created bridge between mating surfaces and extremely low contact resistance providing stable and reliable connections. Its polarized design makes ensure the connector is easily mated and its low profile helps provide better board space utilization.The connectors feature high-precise plastic moulding, compliant with RoHS standards. Its insulation resistance is 10^9 MΩ. The contact resistance at the initial plugging is less than 0.20mΩ. It also offers a 1.50A with 20mΩ of maximum steady-state current rating and an 8A pulse capacity with 4mΩ initial contact resistance.

Industrial Standards

The connectors meet high quality industry standards such as CSA, EN 62004-5-1, and UL 94 V-0. Additionally, the connectors comply with IEC 60512-99-018 for plugging performance and MIL-STD-214 for environmental resistance.

Installation

There are two standard installation methods for 77313-120-30LF:

• Snap in: This method requires a notch cut into the PCB and is generally used with 200/440 Series terminal blocks.
• Through-hole: This is the most commonly used method and requires careful folding of the pins into the PCB with the help of soldering technique.

Conclusion

77313-120-30LF is a rectangular connector – headers, male pins designed for high-density and high-speed application fields. Its low profile and contact resistance provide reliable and stable connections. The connectors comply with various industry standards such as CSA, UL 94 V-0, MIL-STD-214, and IEC 60512-99-018. There are two standard installation methods for 77313-120-30LF: snap in and through-hole.
