USL Series
0.4 mm Pitch, Insulation-displacement connector (IDC)
The USL series is a 0.4 mm pitch connector for micro coaxial cables (AWG#42). Bulk connection by pressure welding improves the connection reliability and makes the connector compact.
Key Features
Bulk pressure welding improves connection reliability and contributes to miniaturization of devices.
- 0.4 mm pitch, 1.0 mm mated height, and 5.6 mm mating width
- Board side connector is right-angle type; cable side connector is straight type.
- Effective mating length is 0.5 mm.
- Available in 20, 30, and 40 positions
- Lead-free product
Improved Product Strength, Transmission Characteristics, Noise Reduction
- The board-side connector is surrounded by a metal shell to improve noise reduction, product strength, and to strengthen the grounding.
- Ground terminals are provided at multiple points to improve transmission and EMS characteristics.

Case Studies
Problem
With current FPC, noise interruption will occur, and if counter measures are taken, flexibility of FPC is lost and complicates internal wiring, which leads to defects during assembly.
Solution
The USL series metal shell and multiple ground contacts reduced the micro coaxial cables’ noise, flexibility, and bendability and enabled easy wiring within the device.
