5177985-5

Rectangular Connectors make it possible to connect two or more devices electrically without having to permanently attach or solder them together. Arrays, edge type, mezzanines (board-to-board) types are the most commonly used types. Among them, the 5177985-5 application field and working principle is very important. In this article, the introduction of the 5177985-5, its application fields and working principles will be discussed.

Introduction to 5177985-5

The 5177985-5 rectangular connector is a board-to-board, edge type connector made by Amphenol. It has a B-type 2.50mm pitch and a nominal current rating of 20amps. This connector is made from a UL 94V-0 rated material, and is UL approved. The connector also meets requirements of many commercial and military high cycle reliability applications. The rated temperature range for this connector is -55°C to +125°C.

Application Fields

Due to its high current carrying capacity, the 5177985-5 connector is commonly used in a wide variety of applications such as telecommunications, computer systems, automotive electronics, and avionics. This connector is also widely used in medical, aerospace, military, and other high reliability applications. It can also be used in applications requiring high speed transmission, high number of mating and unmating cycles, and some applications under extreme temperature environments.

Working Principle

The 5177985-5 connector utilizes the board-to-board edge type connection, which is achieved by having the complementing contact arrays edge-matched and electrically connected. This provides a reliable and mechanically robust connection. The contacts are precision formed with a single spoke, and the contact/socket designs integrate with spring retention features. This provides an easy and quick connection. The connectors are also keyed to prevent a wrong mating of the board and connector. The contact retention tabs prevent any vibration or torsion from causing disconnection, and the seals protect the connectors from water, dust, and other environmental conditions. The 5177985-5 also features a shrouded design to reduce EMI interference.

Conclusion

The 5177985-5 is a board-to-board edge type rectangular connector, with a 2.50mm pitch. This connector operates at a nominal current rating of 20amps, and offers high current carrying capacity. Additionally, its UL approved and meets requirements of many commercial and military requirements. It is primarily used in applications requiring high cycle reliability and where high speed transmission and a high number of mating/unmating cycles are required. The 5177985-5 utilizes a board-to-board edge type connection, which is achieved through precision formed contacts integrated with retention features. The connectors are also keyed and feature a shrouded design. This ensures a reliable and secure connection, protecting it from environmental conditions and EMI interference.
