USLS Series
Low Profile Stack Mating Type
Our USLS series is 0.4 mm pitch, stack mating type micro coaxial cable connector.
Key Features
Compact Connector with 1.65 mm Stack Height
In addition to stack mating, bulk pressure welding improves connection reliability and makes it more compact.
- It has an effective mating length of 0.35 mm, a low profile of 1.65 mm stack height, and a 3.05 mm mating width. Applicable for high-density printed circuit boards.
- The cable harness can be passed through thin tube of 4mm diameter.
- Available with 20, 30, or 40 positions
- Lead-free product
Stack Mating Type
Easy Positioning and Excellent Workability during Mating
- In our USLS series, the common problem of positioning for stack mating type connectors has been resolved with our advanced technology.
- Stack mating provides superior workability.
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 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.
