Rectangular Connectors - Headers, Receptacles, Female Sockets

The 89891-417H is a high-performance, low-profile rectangular connector designed to meet the power requirements of a variety of applications, including automotive, industrial, and military applications. This connector is designed to meet the MIL-DTL-83513/51 (D38999/51) standard, and features a robust plastic housing, 1.20mm pitch, and gold plated contacts. In addition, the connector is shielded and offers superior protection from electromagnetic interference (EMI).

Application Field

The 89891-417H is an ideal choice for applications requiring a robust high-performance rectangular connector. Examples of such applications include: automotive and heavy-duty engine control systems, military on-board communications, robotics, industrial control systems, and laboratory testing equipment.

In addition, the connector can also be used in harsh environment applications, where it can withstand extreme temperatures and vibration, making it suitable for applications such as extreme drilling rigs and military aircraft. The connector is also widely used in applications that have very high voltage requirements, due to its superior insulation resistance and voltage breakdown ratings.

Working Principle

The 89891-417H uses a shielded, three-part construction to protect signal integrity. The connector features two outer shells, which interlock to form a dielectric seal. The central part of the connector, called the contact insert, contains the metal contacts – either through-hole or edge-type contacts – and is surrounded by a plastic housing that seals the shell halves. The contacts are then terminated onto the PCB using solder, crimps, or press-fit type connections.

The 89891-417H features multiple layers of high-performance insulation materials that can withstand high temperatures and offer superior protection from EMI. The connector also features gold-plating on the contacts, which increases contact reliability and reduces electrical resistance. The contacts are also designed to reduce assembly time through a self-aligning, self-orienting mating system.

Conclusion

The 89891-417H is a reliable, robust, high-performance rectangular connector. It is designed to meet the MIL-DTL-83513/51 (D38999/51) standard and features a shielded three-part construction that protects against EMI, an outer shell that provides superior insulation resistance, high-temperature gold-plated contacts, and a self-aligning, self-orienting mating system.

The 89891-417H is an ideal choice for a variety of applications, including automotive and heavy-duty engine control systems, military on-board communications, robotics, industrial control systems, laboratory testing equipment, extreme drilling rigs, and military aircraft.
