305-068-521-212

Edgeboard Connectors Overview

The EDAC Inc. 305-068-521-212 is a standard card edge connector designed for dual-edge PCB applications. It features 68 positions arranged in two rows with a 0.156-inch (3.96 mm) pitch. The connector accepts board thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm). Constructed with copper alloy contacts featuring gold plating, it ensures reliable signal transmission. The housing is made of green thermoplastic polyester, supporting an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester insulator for thermal stability
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and mounting variations. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference ordering guides for series-specific packaging details.

Edgeboard Connectors Selection Notes

Select this component when a 0.156-inch pitch dual-edge connector is required for panel-mounted applications. Verify that the target printed circuit board falls within the specified thickness tolerance of 0.054 to 0.070 inches. Consider the 68-position capacity relative to available routing space. Evaluate the thermal rating against operational environment requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and pitch options for general-purpose interconnect needs. The 305 series utilizes thermoplastic polyester housings and supports both single and dual-edge configurations. This specific model represents a mid-range position count within the series lineup.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical pitch and position counts. Verify mechanical dimensions and electrical ratings match exactly. Alternative manufacturers may offer compatible parts if interface specifications align perfectly.
