345-048-521-888

Edgeboard Connectors Overview

The EDAC Inc. 345-048-521-888 is a dual-edge female card edge connector designed for through-hole mounting. It features 48 positions with a 0.100-inch (2.54mm) pitch and accepts board thicknesses of 0.054 to 0.070 inches. The contacts are made of copper alloy with gold plating, utilizing a cantilever spring design for reliable engagement. Termination is achieved via wire wrap connections. The housing is constructed from green thermoplastic polyester, providing insulation resistance of 5 GOhms. This component operates within a temperature range of -40°C to 105°C and includes flange features for secure panel installation.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration ensures stable connection for non-specified double-sided cards
• Cantilever spring contact design provides consistent mating force and signal integrity
• Wire wrap termination method supports robust mechanical and electrical joint formation
• Thermoplastic polyester housing offers durable insulation and environmental stability

Edgeboard Connectors Applications

• Industrial control systems requiring reliable I/O connections
• Telecommunications equipment interface modules
• Medical device internal circuit board interconnects
• Aerospace and defense avionics subsystems

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with target PCB trace width and spacing requirements. Confirm RoHS compliance status and lead times directly with authorized distributors, as supply chain conditions may vary. Cross-reference the part number with the latest revision history to avoid obsolete configurations.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge female interface with wire wrap termination is required for high-reliability applications. The 0.100-inch pitch accommodates standard board layouts, while the gold-plated cantilever contacts ensure low contact resistance. Consider the operating temperature range and insulation material properties for harsh environment suitability. Verify that the target card thickness falls within the specified acceptance range for proper mechanical fit.

Edgeboard Connectors Part Context

This component belongs to the EDAC 345 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and termination options to support diverse system architectures. As a specialized interconnect solution, it bridges the gap between rigid PCB assemblies and modular plug-in cards, ensuring secure data and power transmission in compact form factors.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 345/395 datasheet for cross-reference information. Potential substitutes must match the 48-position dual-edge female configuration, 0.100-inch pitch, and wire wrap termination style. Verify identical flange dimensions and board thickness tolerances to maintain mechanical compatibility. Ensure replacement parts meet the same electrical ratings and environmental specifications.
