Rectangular Connectors – Headers, Receptacles, Female Sockets – are among the most common types of interconnects in electrical and electronic application fields. 71991-309HLF is part of the modular receptacle family, an easy and quick alternative to inserting and soldering individual pin connections.

The 71991-309HLF conforms to 2A, the 2 point Data Rate Specification defined by the IEEE 1145 standard. It is a 50-pins surface mount receptacle with half-pitch (0.65 mm) pitch and height of 2.5 mm. It is a high-density interconnect engineered for reliable electrical and mechanical performance in high-speed, high-density applications.

It is a cost-efficient solution ideal for High-Speed Digital applications commonly used in a variety of products in Telecommunications, Networking, Broadcast, Avionics, Automotive and Aerospace, Medical and Industrial Systems.

Working Principle

Electrical signals, power and data, in the form of currents, voltages, digital codes, waves, pulses or a combination of them, in the 71991-309HLF application move along the interconnects, either internal or external of the equipment. It is the popularity of this type of interconnections due to the easy installation of the receptacle with profile side rails which guarantees a robust connection.

The 71991-309HLF receptacle consists of two mating sections, one fixed and one moving, with which the pin sockets, plugs and headers are placed. The fixed portion is the contact matrix which secures the pins or header by its angular shape. It offers the advantage of being capable to safely withstanding pressures and minimizes soldering damages during mating and unmating mated connector. The moving section of the connector stands for the contact pivot which allows the pins to move to be mated.

The holes and pockets formed by the contact matrix and pivot are interconnected by channels incorporated in the system. These channels allow the pass of the signal, medium or power flows in respective directions and thus direct them to the circuit boards or subsystems or systems.
