1.27 mm SRC Single Row Connector - MiniBridge™ Cable System

The small size of the single-row, 1.27 mm pitch SRC connec-tor system makes it ideal for space-saving board to cableconnections. The cable connector system is used in the widestrange of applications in various sectors such as automotive,industrial, consumer or medical. The versatile applications canbe realized thanks to the various connection options, with rightangle or vertical male connectors and female connectors with90° or 180° cable outlet.The male connector is available with SMT terminals, the femaleconnector has IDC cable connections. The plastic housing ofthe male connector is able to withstand high temperatures, so the connector is suitable for lead-free reflow soldering pro-cesses. The male connectors are available in tape-and-reelpackaging for automatic assembly.With the female connector the cable guide ensures that attach-ing the cable or single strands is a simple operation. Standard cable assemblies are available. Customized cableassemlies can be easy ordered on request.

1.27 mm SRC Single Row Connector - MiniBridge™ Cable SystemCable Assemblies

Standard cable assemblies are available from ERNI. Thanksto the versatile options of our female connectors, the widestrange of applications can be realized. The female connectorsare available with different types of locking latches for normalvibration/shock loads (black model) as well as applicationsinvolving heavy vibration/shock loads (red model). The robust version (red) requires a tool for releasing. The IDCterminal is designed for AWG-24 or AWG-26 conductors(solid or stranded). Partial loading is also possible using singlewire. Cable outlet is 90° or 180°.
