2.54 mm Pitch Ejector Header Connector

Note: Available with short or long ejector latches, polarization options, and various plating thicknesses. Custom pin counts and ejection force specifications available.

1. Dual-Side Stainless Steel Ejector for Secure PCB Mounting
Features stainless steel dual-side actuation ejector mechanism - providing secure board retention and easy removal. Ideal for applications requiring frequent board changes, such as test fixtures, module carriers, expansion cards, and removable daughter boards.

2. Flexible Pitch Options for Various Density Requirements
Available in 1.27mm, 2.0mm, and 2.54mm pitch options - supporting dual row configurations from 10 to 64 pins. Choose the pitch that matches your PCB space and I/O density requirements, from compact designs to standard legacy interfaces.

3. Reliable Electrical Performance for Signal and Power
Rated at 1A to 3A per pin with 250V AC/DC - suitable for both signal transmission and low-power delivery. Contact resistance ≤20 mΩ and insulation resistance ≥1000 MΩ ensure consistent, stable electrical performance for demanding applications.

4. Premium Materials with UL94V-0 Flame Rating
Phosphor bronze contacts with gold or tin plating over nickel provide excellent conductivity and corrosion resistance. Housing molded from PBT or PA6T with UL94V-0 flame rating offers superior thermal stability and fire safety. Available in through-hole or right-angle mounting styles.

• Ejector Types: Short latch (standard), long latch (extended reach), or single-side ejector
• Ejector Color: Standard gray, black, or custom colors for identification
• Contact Plating: Tin (economical), gold flash (0.1μm), selective gold (0.3-0.8μm), or full gold (1μm+)
• Mounting Styles: Vertical through-hole, right-angle (90°), or SMT (select versions)
• Polarization Options: Center polarization, offset polarization, or custom keying
• Housing Features: Standoffs for PCB cleaning, pick-and-place compatible, or high-temperature materials

User-Friendly Connector Solutions for Frequent Interface Applications

• Programming & Debug Stations: Essential for development boards, microcontroller programmers, and JTAG interfaces where frequent cable connection and disconnection occurs, enabling quick changes without damaging connectors or requiring tools.
• Test Fixtures & Burn-In Racks: Used in production test equipment where multiple devices are repeatedly connected and removed, with ejector mechanisms reducing operator fatigue and ensuring proper connector engagement before testing.
• Industrial Control Panels: Deployed in PLC programming ports, HMI interfaces, and machine control cabinets where maintenance technicians need quick access for diagnostics and program updates without struggling with tight connectors.
• Educational & Training Equipment: Integrated into training boards, educational kits, and laboratory equipment where students frequently connect and disconnect ribbon cables during experiments and learning activities.
• Data Communication Equipment: Used in network switches, routers, and patch panels for console ports and management interfaces requiring occasional technician access with secure retention during operation.
• Medical Device Service Ports: Implemented in diagnostic equipment and patient monitoring systems where service technicians require reliable access for software updates and diagnostics with easy disconnect capability.

1.Michael Chen, Test Engineering Manager, PCB Assembly Services
"Ejector headers on our programming fixtures have reduced operator fatigue significantly. The smooth ejector action allows quick board changes while the secure latch ensures proper connection during programming cycles."

2.Sarah Wang, Hardware Developer, Embedded Systems
"Essential for our development boards. Engineers appreciate the easy disconnect feature when swapping between multiple prototype boards, and the robust construction withstands daily lab use."

3.Robert Zhang, Industrial Controls Engineer, Factory Automation
"Used for PLC programming ports in our control cabinets. The ejector mechanism allows maintenance technicians to connect and disconnect quickly, even with gloves on, while maintaining reliable connections during operation."

4.Lisa Park, Test Engineer, Automotive Electronics
"Critical for our burn-in test racks. The dual-side ejectors provide balanced removal force, preventing PCB stress during repeated connection cycles across thousands of test iterations."

5.David Liu, Educational Equipment Designer, University Labs
"Perfect for student training boards. The easy eject mechanism encourages proper handling, and the durable design survives years of student use without contact damage or latch failure."
