Rectangular Connectors - Headers, Receptacles, Female Sockets

89891-404H Application Field and Working Principle

The 89891-404H rectangular connectors are a type of female sockets that are applicable to militaries, aerospace, industrial, automotive, and plant control applications. It is a connector that is compliant with MIL-DTL-5015 sizing standards (X and XX series) and with up to 2 rows per column. It is common for use with hybrid and/or high-density applications for printed circuit boards and to transmit/distribute power, signals, and data. It has an operating voltage of 600V AC and a current capacity of 16A.

The 89891-404H is a termination interface that is designed to provide reliable power, signal and data transmission without being affected by vibration, temperature fluctuations, or EMI. It is constructed with stamped and formed phosphor bronze, with a UL 94V-0-rated thermoplastic shell for improved environmental protection. Connectors come with either straight or 90-degree contacts, depending on the application, with either MIL-DTL-38999, MIL-DTL-5015 and/or ARINC 600 standard size options. The 89891-404H can be used in a Picoflex or on a D-sub connector.

The 89891-404H has a contact layout that is designed to provide maximum performance in any application. The contacts are arranged in a “mezzanine” pattern to reduce impedance, meaning that the contact from one row off-sets that of the adjacent row. This improves the signal integrity and lowers attenuation when large currents are passed, resulting in an improved performance when in use. The contacts are also designed to have a quick and easy release, making for quick connection and disconnection.

The 89891-404H connectors are also made with a scoop-proof design. This feature is designed to ensure that the contacts can only be connected in the proper orientation, meaning that any attempted “scooping” or misalignment, will result in the connector’s pins not engaging with the female sockets. This is an important safety feature, as it helps to prevent misalignment of connectors that could lead to damaged equipment or circuits.

The 89891-404H is also designed with a peak voltage rating of 350V. This is an important featu
