Rectangular Connectors - Headers, Male Pins, fall into the category of connectors used to transport signals and power in electronic and electrical components. 87220-8 is one such rectangular connector; it is often used in applications characterized by particularly tight spaces and high frequency signals. 87220-8 connectors have a wide range of features that make them suitable for many different applications, as well as a working principle that is specific to this type of connector.

87220-8 connectors utilize a 50-ohm impedance for transmission, which allows them to be reliable in many electronic and electrical applications. The connectors have a height of 12.5 mm, allowing them to fit into most tight spaces while still providing a strong connection. It is also shielded against both environmental forces and electromagnetic interference. In addition, it is RoHS2 compliant and rated to an IP67 level for dust- and water-tight applications.

The terminal positions of this connector are divided into two rows; the first row has four positions while the second row contains three. The terminal contacts are also divided into two rows, each containing three positions. These design choices allow the connector to maximize signal density while still operating effectively. The terminal pads are made from gold-plated phosphor bronze for increased durability and provide a wide range of contact force to ensure a strong connection in any application.

In terms of the working principle, 87220-8 connectors rely on a threaded mating couple that is screwed onto a terminal. This coupled with its polarized design ensures that the assembly is accurate and secure. In addition, the positive detent provides an audible and tactile feedback when the mating actually occurs, preventing against incorrect assembly. When assembled, the contact resistance of the male and female terminals is consistently within five milliohms. The mated connectors achieve a 75% contact force, preventing the connector from coming undone unintentionally.

Overall, 87220-8 connectors provide a reliable, secure connection and strong signal transmission for a range of applications. The threaded mating couples and contact resistance consistency make this connector well-suited for high-fidelity applications. With a high-frequency signal capacity, a wide range of terminal positions, and a small form factor, 87220-8 connectors are an ideal choice for many electronic and electrical applications that require a reliable connection in a tight space.
