Rectangular Connectors - Headers, Receptacles, Female Sockets

The SSQ-112-03-F-D-RA series are a type of rectangular connectors, primarily used in the electrical and electronics industries, which consist of a header, a mated receptacle, and a female socket component. These connectors are commonly used to connect cables between different electrical components and circuits, or in a range of other applications such as distributing power or signal within a device. It is the combination of a header, receptacle and female socket that provides a reliable and economical connection.

Application Field

The SSQ-112-03-F-D-RA connectors are ideal for a variety of applications, including industrial controls, power applications, audio and video equipment, automotive, lighting, test and measurement and other field service applications. The compact size makes them suitable for applications where space is limited, such as robotics, medical and consumer electronics.

The SSQ-112-03-F-D-RA series are UL recognized components, compliant with UL 94V-2 flammability specifications, which make them suitable for applications requiring high reliability and safety. The connectors offer good shielding and EMI protection, which makes them suitable for use in EMI-sensitive environments. They are also RoHS compliant, are rated for a wide operating temperature range (-55°C to +125°C depending on contacts used) and are capable of operating at high speed.

Working Principle

The SSQ-112-03-F-D-RA series of rectangular connectors consist of two distinct parts, a header and a mated receptacle. The header is the larger of the two components, with multiple contacts mounted along its length. These are usually metal plungers, but can also be made from other materials. The mated receptacle is the smaller component, with multiple signal contacts mounted along its length.

When the header and receptacle are mated, each metal plunger contacts its corresponding signal contact in the receptacle, completing the electrical circuit. The mechanical locking device on either component provides a secure connection, preventing the connection from becoming loose or disconnected. In applications requiring multiple connections, multiple headers and mated receptacles can be connected to each other, creating an array of multiple connectors.

The female sockets of this series are also available and can be used instead of headers to provide a keyed, semi-permanent connection. The female sockets consist of a central pin or socket and two peripheral contact pins. Inserting the center pin into the header completes the circuit, and the mechanical locking feature ensures that the connection is secure. The female sockets are ideal for applications requiring a keyed connection, as they prevent unauthorized access.

The SSQ-112-03-F-D-RA series of rectangular connectors offer reliable and secure connections in a range of applications. The connectors are designed for ease of use and installation, and with the varied components available, they can be tailored to suit a variety of requirements. Additionally, the connectors are UL approved and RoHS compliant, making them suitable for a wide range of demanding applications.
