Rectangular Connectors - Headers, Male Pins is widely applicable across the electronics industry. This article covers the application and working principle of 280390-2, a popular variety of the family of Rectangular Connectors - Headers, Male Pins connectors.

280390-2 connectors are mainly used in low-frequency (up to 1GHz) high-density signals and mixed signal powerful connector systems. This connector is of great popularity due to its capability to arrange rigid, shielded and simple interconnection of a large number of signals in a very small space. Its widely used in the medical, consumer electronics, aerospace, automotive, instrumentation, and data and telecommunications industries.

The 280390-2 has an insulator material made of black thermoplastic UL94V-0 rated. Its contacting material is brass, with gold plating on the contact surface, providing very good electrical contact and a reliable connection. The main feature that distinguishes it from other rectangular connectors - headers, male pins is its connection hood capacity to hold connectors with a center of gravity offset from the housing & board center, making it more versatile than most other designs. This feature helps avoid misalignment and ensures reliable connection.

The connection hood of the 280390-2 is formed by two overlapping parts. The first part sits flush against the board and contains the male pins, which connect the connector to the board. The second part overlaps and covers the first portion, providing reliable electrical contact and mechanical protection for the connection. The connection hood is secured in place by two screws, which ensure a pressure-tight connection.

281 390-2 connectors feature a male connector with 4 or 6 pins. It has a contact resistance of 50mohm maximum and a current rating of 1A AG. Its operating temperature range is -55°C to +105°C. The shield feature provided by this connector is excellent as it has DF1002/ SM1002 grade shielding with a frequency range of up to 1GHz.

The working principle of the 280390-2 is quite simple. When the connector is plugged in, the male connector pins make contact with the female connector’s receptacles inside the connector hood. This creates a reliable electrical connection. Additionally, the two overlapping portions of the connection hood ensure that the connection is secure and prevents any disconnection from happening.

In conclusion, 280390-2 Rectangular Connectors - Headers, Male Pins is a great choice for anyone looking for a reliable, rugged and compact connector that offers good electrical reliability and design flexibility. It is highly rated and is being used in many industries due to its excellent features.
