Rectangular Connectors – Headers, Receptacles, Female Sockets

Rectangular connectors are the most common type of connectors used in the electrical industry today:

• Headers – connectors that attach to a circuit board;
• Receptacles – connectors that attach to a cable; and
• Female sockets – connectors used in receptacle applications.

At the heart of a rectangular connector is its application field and working principle. This is exemplified by the SSW-105-04-FM-S-RA connector. This is a four-way, zero insertion force (ZIF) socket connector that is among the most popular headers in the field.

The application of the SSW-105-04-FM-S-RA begins with its size. It has an overall length of 1.08 inches, which makes it small enough to be easily used in tight spaces. The pins are spaced in a 0.05-inch interval. This spacing allows the connector to comfortably fit to a circuit board or cable once installed without leaving too much of a gap in between.

In terms of its working principle, the SSW-105-04-FM-S-RA is a ZIF socket connector. As such, it requires no insertion force for connection. The pins have a polarization that ensures they are always connected in the correct orientation. This jumperless effect eliminates the need for onboard jumpers or additional wiring of the connector.

The SSW-105-04-FM-S-RA also offers a secure connection to its system. It has dual-row contacts, with dual beam contact on each row, which increases its electrical performance and ensures a more reliable system. The contact force is also improved, allowing the connector to endure a higher number of mating cycles.

Installation of the SSW-105-04-FM-S-RA is also easy. It offers snap-in termination housing that can be easily mounted on the surface of a circuit board. Additionally, it requires no screws for installation, making it simpler and more cost-effective.

In conclusion, the SSW-105-04-FM-S-RA is a zero insertion force (ZIF) socket connector that is used for headers in rectangular connectors. It is ideal for tight spaces, has a jumperless connection, and offers improved contact force and secure installation.
