2.54mm Pitch Wafer Connector

Note: Available with pre-assembled contacts or for use with standard crimp terminals. Custom pin counts and polarization options available.

1. Industry-Standard 2.54mm Pitch for Universal Compatibility
Features the widely adopted 2.54mm (0.1 inch) pitch supporting 2 to 40 pins (even numbers standard) - directly compatible with breadboards, development boards, and legacy PCB designs. Perfect for prototyping, industrial controls, consumer electronics, and embedded systems.

2. Dual Mounting Options for Design Flexibility
Available in through-hole or surface mount (SMT) styles, with vertical or right-angle orientation options - allowing you to choose the best mounting method for your PCB layout and assembly process. Compatible with manual soldering, wave soldering, and reflow processes.

3. Reliable Electrical Performance for Power and Signal
Rated at 250V AC/DC with contact resistance ≤10-20 mΩ and insulation resistance ≥1000 MΩ - ensuring stable, consistent electrical performance. Suitable for both power delivery and signal transmission across a wide range of applications.

4. Premium Materials with Wide Operating Temperature
Brass or phosphor bronze contacts with tin or gold plating over nickel provide excellent conductivity and corrosion resistance. Operating temperature range from -40°C to +105°C ensures reliable performance in extreme environments - from freezing outdoor installations to high-heat industrial equipment.

1. Versatile Mounting for Any PCB Layout
Available in through-hole or surface mount (SMT) styles, with vertical or right-angle orientation options. This 2.54mm pitch connector fits virtually any PCB design - from compact vertical stacking to space-saving right-angle edge connections.

2. Wide Temperature Range for Demanding Environments
Rated for operation from -40°C to +105°C, this connector performs reliably in extreme cold or high heat. Whether deployed in outdoor equipment, automotive systems, or industrial controls, it maintains stable signal integrity across the full temperature range.

3. Low Contact Resistance for Clean Signal Transmission
With contact resistance as low as 10–20 mΩ and insulation resistance ≥1000 MΩ, this connector minimizes signal loss and cross-talk. Brass or phosphor bronze contacts with tin or gold plating ensure consistent electrical performance over ≥200 mating cycles.

4. Standard 2.54mm Pitch with Flexible Pin Counts
Supporting 2 to 40 pins (even numbers standard), this connector uses the widely adopted 2.54mm (0.1 inch) pitch. It directly replaces legacy designs and integrates seamlessly into existing PCB layouts, reducing redesign time and inventory costs.
