2.54 mm Card Edge Connector

Note: Available with various mounting options, card guides, and polarization keys. Custom contact positions and specialized plating available.

1. Industry-Standard 2.54mm Pitch for Maximum Compatibility
Features the widely adopted 2.54mm (0.1 inch) pitch - directly compatible with most breadboards, development boards, and legacy PCB designs. Available in single or dual row configurations supporting 6 to 86 contact positions for maximum design flexibility.

2. High Current Rating up to 5A per Contact
Rated from 3A to 5A per contact with 250V AC/DC - delivering exceptional power capacity for a 2.54mm pitch connector. Contact resistance ≤15 mΩ and insulation resistance ≥5000 MΩ ensure superior electrical performance for demanding power and signal applications.

3. Premium Contact Materials with Gold/Tin Plating
Phosphor bronze or beryllium copper contacts provide excellent conductivity and mechanical durability. Gold or tin plating over nickel (0.1-0.8μm) ensures corrosion resistance and reliable signal integrity over extended service life.

4. Multiple Mounting Styles for Any Assembly Process
Available in solder eyelet, solder dip, or wire wrap mounting styles - accommodating various termination requirements from PCB soldering to backplane wire wrapping. Perfect for industrial controls, telecommunications equipment, test fixtures, and legacy system upgrades.

• Contact Positions: Standard from 6 to 86 contacts, custom counts available
• Row Configurations: Single row, dual row, or staggered arrangements
• Card Thickness: Standard 1.6mm, optional 0.8mm, 1.2mm, 2.4mm, or custom
• Contact Plating: Gold flash (0.1μm), selective gold (0.3-0.8μm), full gold (1μm+), or bright tin
• Mounting Styles: Solder eyelet, solder dip, wire wrap, or right-angle
• Termination Types: Standard solder cup, PCB mount, or extended tails for wire wrapping
• Mounting Hardware: Threaded inserts, mounting ears, card guides, or ejector mechanisms
• Contact Design: Bifurcated (dual-beam) for redundant contact, or single-beam for cost optimization
• Polarization Options: Key slots, missing contacts, or custom polarization keys
• Housing Materials: Standard phenolic, glass-filled polyester, or high-temperature thermoplastics
• Color Coding: Green (standard), black, brown, or custom colors

Standard Pitch Card Edge Solutions for Diverse Applications

• Industrial Control Systems: Used in PLC modules, motor drives, and industrial I/O cards where the 2.54mm pitch provides reliable, high-current connections for control signals and power distribution in factory automation environments.
• Test & Measurement Equipment: Deployed in modular test instruments, data loggers, and bench top equipment where interchangeable function cards require robust, repeatable connections for accurate measurements and long instrument life.
• Legacy Bus Systems: Essential for ISA, PC/104, and other legacy bus architectures still used in industrial and military applications, providing backward compatibility with proven technology.
• Educational & Training Platforms: Integrated into educational trainers, prototyping systems, and university lab equipment where the standard pitch aligns with breadboard-compatible designs for student learning.
• Custom Interface Boards: Used in adapter cards, riser boards, and custom interface designs requiring reliable edge connections with proven mechanical stability and straightforward PCB layout.
• Backplane & Motherboard Systems: Deployed in card-cage systems, rack-mount equipment, and telecommunications chassis where multiple cards connect to a common backplane for modular system architecture.

1.Michael Chen, Controls Engineer, Factory Automation
"Standardized on 2.54mm card edge connectors for all our PLC I/O modules. The bifurcated contacts ensure reliable connections even under vibration, and the 5A current rating handles our industrial sensor loads without issue."

2.Sarah Wang, Test Equipment Designer, Measurement Solutions
"Used for interchangeable function cards in our bench top analyzers. The robust construction withstands hundreds of card swaps, and the gold-plated contacts maintain low resistance for accurate measurements."

3.Robert Zhang, Industrial Systems Integrator, Legacy Equipment
"Critical for maintaining legacy PC/104 systems in our manufacturing lines. These connectors provide reliable drop-in replacements that keep our 20-year-old equipment running with zero compatibility issues."

4.Lisa Park, Educational Lab Manager, University Engineering
"Perfect for student prototyping stations. The standard 0.1-inch pitch aligns perfectly with our breadboard accessories, and the durable construction survives years of student use without failure."
