Key Features

Industry’s Smallest Pitch (0.25 mm) Space Saving

Industry’s Smallest Pitch (0.25 mm) Space Saving

  • Compact connector with mated height of 1.44 mm and mating width of 3.05 mm
  • Effective mating length is 0.31 mm
Excellent Transmission Characteristics Enable Flexible Connection Layouts

Excellent Transmission Characteristics Enable Flexible Connection Layouts

  • Applicable cable: AWG#44/46
  • Highly flexible cable allows flexible connection layout between boards.
  • The cable harness can be passed through thin tube of φ2.7 mm at the hinge area, etc., which expands the user’s board design.
  • The bottom surface of the connector is covered with resin, which allows wiring patterns directly under the connector.
Medical

Secure & Reliable Connection with High Transmission Characteristics

  • The signal lines are soldered using pulse heating to ensure stable and reliable connections.
  • The board-side connector is surrounded by a metal shell to improve noise reduction, product strength, and to strengthen grounding.
  • Ground terminals are provided at multiple points to improve transmission and EMS characteristics.
  • A nickel barrier is placed on the board-side contact to prevent the solder from lifting.

Case Studies

Problem

With another brand’s connector and FPC, noise interference was occurring, and due to its structure, a suitable wiring connection was impossible.

Solution

The XSLS series metal shell and multiple ground terminals reduced the noise. The flexibility of the micro coaxial cables realized ideal wiring.
