SSQ-126-02-F-Q-RA

Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors are simple yet essential components of any communication or electronic system.From cell phones to computers to satellites, these versatile components enable the safe and reliable transfer of signals or power. The SSQ-126-02-F-Q-RA is a single-row, 2-position socket header with tin plated receptacles. It effectively connects small gauge stranded wires and solid copper conductors to create a safe electrical pathway.

Application Field

The SSQ-126-02-F-Q-RA is commonly used in general purpose applications such as instrumentation, UPS, appliance and lamp systems, and medical electrics. It is suitable for applications where high density and low profile are key features, as well as larger systems which require more reliable connections. The SSQ-126-02-F-Q-RA can also be used with boards that incorporate sliding contacts. Such boards allow electrical contact between the output and input of the socket connector.

Mechanical Construction

The SSQ-126-02-F-Q-RA is constructed of a rectangular shaped solid plastic body with rigid durability. The header includes an adequately sized bushing, a significant feature for high amperage applications. The metal contacts are protected with mica washers, which minimizes electrical contact between the header and receptacle. It also features metal retention clips with slots to help maintain the secure connection needed.

Electrical Characteristics

The SSQ-126-02-F-Q-RA’s contact material is a corrosion-resistant and gold-plated copper alloy. This provides for excellent electrical, thermal and mechanical properties as well as reliable connections. It has withstanding voltages of up to 250VDC, and the current rating at 40°C ambient temperature is 5A. The contact resistance at the interface between the socket and header connectors is 0.2mΩmaximum, when tested at a contact pressure of 20N minimum. Additional features include an operating temperature range of -55°C to +125°C and a dielectric withstanding voltage of 1000VAC.

Working Principle

When the SSQ-126-02-F-Q-RA is being connected, it relies on a simple and effective design to create an electrical interconnection between the headers and receptacles. The mica washers ensure a secure contact is maintained, and the metal retention clips slide over the bushing and act to lock both components together in the locked position. The contact pins of the tri-metal socket also slide into the holes of the socket and make electrical contact, creating an electrical circuit.

Conclusion

The SSQ-126-02-F-Q-RA is a versatile and reliable single-row 2-position socket header with tin plated receptacles for solderless connection. It is commonly used in general purpose applications such as instrumentation, UPS, appliance and lamp systems, and medical electrics. It has a high current rating, excellent thermal and mechanical properties and a corrosion resistant gold-plated connector contact. Withstanding voltages up to 250 volts, the SSQ-126-02-F-Q-RA ensures safe and reliable transfers of signals or power.
