307-026-542-212

Edgeboard Connectors Overview

The EDAC Inc. 307-026-542-212 is a standard card edge connector from the 307 Series, designed for dual female contact configurations with 26 positions. It features a 3.96 mm (0.156 inch) contact spacing and a 5.08 mm row spacing to accommodate double-sided PCBs. The connector accepts a nominal board thickness of 1.57 mm and utilizes gold-plated copper alloy contacts rated for 5 A current. Constructed with a thermoplastic polyester housing, it supports wire wrap termination and operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure mating with double-sided card edge boards
• Gold-plated copper alloy contacts ensure reliable electrical performance and corrosion resistance
• Thermoplastic polyester housing provides durable insulation and structural stability
• Wire wrap termination method allows for flexible and robust circuit interconnections

Edgeboard Connectors Applications

• Industrial control systems requiring high-reliability board-to-board connections
• Telecommunications equipment utilizing modular card architectures
• Test and measurement instruments needing stable signal transmission
• Computing hardware interfaces supporting double-sided printed circuit boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, orientation, and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the wire wrap termination aligns with the assembly process. Cross-reference the RoHS compliance status and operating temperature range requirements with the system specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface is required for double-sided cards with a 1.57 mm thickness. The 3.96 mm pitch suits applications needing wider spacing between signal lines compared to finer pitches. Consider the wire wrap termination if manual or semi-automated wiring is preferred over soldering. Evaluate the 5 A current rating against the maximum load requirements of the connected circuits to ensure safe operation under thermal conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 Series of card edge connectors, which are engineered for general-purpose electronic interconnects. The series offers various position counts and mounting options to support diverse board dimensions. As a standard connector, it integrates into larger assemblies where modular expansion or replacement of circuit cards is necessary, providing a standardized mechanical and electrical interface across different system designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 26-position count, 3.96 mm pitch, and dual female configuration. Verify that alternative parts support the same 1.57 mm board thickness and wire wrap termination. Check for equivalent current ratings and material compositions to maintain environmental resilience. Consult manufacturer cross-reference lists for verified compatible replacements ensuring identical form, fit, and function.
