Datasheet

A new concept in PCB connection technology has been introduced by RS Components with the introduction of the SKEDD SDC 2,5 series of solderless direct wire-to-board connectors from Phoenix Contact. SKEDD technology from Würth Elektronik, and further developed by Phoenix, uses push-in spring contacts manufactured to fit PCB hole geometries perfectly. No soldering or press fitting is needed.

Wires and cables can be plugged directly into a PCB without the need for a board-mounted header, eliminating an entire connection level and reducing component count.

Wire-to-board connections can be made lighter and lower profile, supporting device miniaturisation. Compared to conventional header-and-socket configurations, this new technology allows greater flexibility in positioning connectors and can reduce process time, cost, and the risk of manufacturing errors.

The Phoenix Contact SDC 2,5 range incorporates SKEDD technology in a series of wire-to-board connectors with from 1 to 16 tin plated contacts at 5mm pitch.

Nominal cross-section is 2.5mm2, nominal current is 12A, and rated voltage (III/2) is 320V.

Assembly is intuitive thanks to a colour differentiated actuation lever, and connection quality is unaffected by multiple insertions and extractions.

A secure locking mechanism between the connector housing and the PCB ensures a robust, reliable, vibration-resistant mechanical connection, even under harsh environmental conditions.

An integrated test option provides for quick and easy connector testing.
