Connection convenience redefined: as a market leader in PCB connection technology, Phoenix Contact is introducing direct connectors with SKEDD technology. The PCB connectors can be connected directly to the PCB via through-contacted drill holes. Mount and remove the connectors easily without a tool. No headers are required, which eliminates the need for complex soldering processes and saves costs.
[x]- SKEDD direct-connection technology enables flexible positioning on the PCB
Direct connectors with crimp or Push-in spring connection: mount connectors quickly and easily on your PCB. Positioning, insertion, latching: the PCB connectors can be connected directly to the PCB via through-contacted drill holes. Additional headers are not required, which means that component and process costs can be reduced. The connectors with up to 16-position versions are available with a pitch of 5.0 mm, and with a pitch of 3.5 mm with a maximum of 32 positions. The SKEDD connectors of the SDC/SDDC series feature a Push-in connection. The CDDC series connectors are available with crimp connection.

Press-in technology, wave soldering, THR soldering, and SMT soldering are established in PCB assembly. None of these are needed with the SKEDD direct-connection technology. Integrate through-contacted drill holes anywhere on the PCB. giving you a whole new level of flexibility when it comes to your PCB layout.
For the first time, SKEDD direct-connection technology enables directly pluggable and detachable connections at any position on the PCB. SKEDD contacts consist of two spring-loaded slightly curved contact handles that adapt to the diameter of the PCB drill holes and make reliable contact. Direct connectors therefore do not require any headers and are connected directly by hand, tool-free.
Body-bound rivets on the side ensure a firm connection, even in case of mechanical loads such as vibrations. The SKEDD direct connectors are qualified for 25 plugging and unplugging cycles. They have passed the vibration test in accordance with DIN EN 60068-2-8 with an acceleration of approx. 50 m/s² with a frequency cross-section of 60.1 Hz to 150 Hz.
The innovative direct connectors enable straightforward implementation of applications that require a conductor connection on the rear of the PCB. With the SKEDD direct-connection technology, there is no need for a manual soldering process for integration of additional PCB connection technology.
You can even connect the preassembled SKEDD direct connectors to the PCB during production and therefore wire several PCBs in the device. To integrate additional functions, all you need to do is provide through-contacted drill holes on the motherboard. You can then easily integrate further SKEDD direct connectors as required.
With SKEDD direct connectors, you can create simple distributor boards, which do not require an increased degree of protection, for example for connecting I/O devices to a controller. Thanks to direct-connection technology, the entire PCB can be assembled without a soldering process.
The innovative SKEDD direct-connection technology enables you to plug the PCB connectors directly onto the PCB. Complex soldering processes are no longer necessary. The connection is tool-free, its long-term stability and its electrical connection are ensured by through-contacted holes. With Push-in technology, conductors can be connected quickly and easily; connectors with crimp connection are ideal for preassembled cables. The video explains the technology in more detail.

SKEDD direct connectors from Phoenix Contact are qualified for standard PCBs that are 1.6 mm thick with a chemically tin-coated or HAL surface (Hot Air Leveling). They have no further material or surface requirements. During PCB production, it must simply be ensured that tin-coated and through-contacted drill holes are provided for the SKEDD contacts and untinned drill holes are provided for the interlocking and guide pins.
The adjacent figure shows the inside diameter of the bore holes for SDC 2,5 contacts.
Unlike standard PCB terminal blocks and headers, or special components for surface mounting (SMD = Surface Mount Device), the SKEDD direct connectors are not soldered in place. The soldering process used therefore only depends on the other electromechanical and electric components on the PCB. If the wave soldering process is used on the PCB, the provided drill holes can be covered with the soldering frame, Kapton band, or a blue mask to prevent any unwanted solder residue. If the THR or SMD process is used on the PCB, the drill holes can be protected by soldering templates.
The SKEDD direct connectors are mounted manually following the soldering process and before final assembly of the device. The connectors are connected manually and secured using the body-bound rivets on the side. If the connectors are positioned closely beside one another and the body-bound rivets therefore cannot easily be operated by hand, they can also be locked using a screwdriver, thanks to their grooves and contact surfaces.
The crimp connection guarantees connection convenience for high volumes. This means that the preassembled conductors can be connected to the connectors quickly, easily, and, above all, inexpensively. Use qualified tools for crimping and benefit from a high level of operating convenience. The manual crimping pliers and the quick-change tool are available to match the respective crimp contacts. The manual crimping pliers are included in the Phoenix Contact portfolio and can be ordered via our website. The quick-change tool is available from Demirel Crimp Technik GmbH.
SKEDD direct connectors of the SDC and SDDC series are approved in accordance with UL 1059, CAN/CSA C22.2 No. 158-10, and DIN EN 61984 (connector standard). VDE and UL approvals have been commissioned for the CDDC range of products.
The direct connectors meet the requirements of the glow-wire test in accordance with DIN EN 60335-1 (household appliances standard). Information on the glow-wire ignition temperature (GWIT) and glow-wire flammability rating (GWFI) is detailed in the product data sheets.
In addition, all three product ranges have passed the durability test in accordance with DIN EN 61373:2011-03 (Shock and vibration testing for railway applications) in category 1 and class B.
