Rectangular Connectors - Headers, Male Pins provide a means of connecting printed circuit boards, cables and wires. A wide range of products are available, including the 87221-5 series, which offer reliable data transmission in a variety of application fields. This article discusses the range of applications suitable for 87221-5 connectors, as well as their basic working principle.

Introduction to 87221-5 Connectors

87221-5 are high-performance male pins featuring a robust design with a 0.64 mm pitch. With five-partition structure, the pins are designed to complement female connectors and provide reliable contact connection with low field impedance. Suitable for press-fit or soldering connections in card-edge connectors, the connectors are made of phosphor bronze and are tin-plated for reliable electrical conductivity. Their low insertion force offers easy connection and disconnection making them a suitable option for various signal transmission applications. Furthermore, the 87221-5 range is versatile and offer a comprehensive selection of pin groupings, configurations and mounting orientations.

Application Fields of 87221-5 Connectors

87221-5 connectors offer a reliable link for assemblies of wiring boards, panels, cables and device connectors in various application fields such as aviation, commercial, industrial, medical and automotive industries. Due to their high quality and moulded construction, the 87221-5 are especially suited for applications that require a high-reliability such as data and signal transmission in high-speed networks and harsh environment operations. Such applications are found in data centers, public networks, industrial automation systems, automobile electronics, etc.

Working Principle of 87221-5 Connectors

The exceptional performance of 87221-5 connectors is attributed to their design and construction. The five-partition structure of the male part enables the 87221-5 to provide reliable contact connection with low field impedance. The 87221-5 also feature a strain relief and a heat resistant housing which provide added protection against mechanical and environmental hazards. The tin-plated contacts within the connectors are designed to reduce contact resistance and ensure optimum contact over time.

The 87221-5 connector is designed for press-fit or soldering connections in card-edge connectors. The press-fit connection requires the male pins to be inserted into the female connector and fastened with a positive retention mechanism. The soldering technique requires the contacts to be soldered firmly onto the mating PCB. The 87221-5 is a standard male pin and is compatible with both press-fit and soldering connections.

Conclusion

Designed and manufactured for superior performance and reliability, 87221-5 are suitable for providing connections and data transmission in a variety of application fields. Their five-partition design provides low field impedance and ensures reliable contact connection. The tin-plated contacts provide excellent electrical conductivity and low contact resistance over time. The 87221-5 is versatile and offer a comprehensive selection of pin groupings, configurations and mounting orientations.
