305-034-556-202

Edgeboard Connectors Overview

The EDAC Inc. 305-034-556-202 is a dual-row card edge connector designed for board-to-board applications. It features 34 positions with a 0.156-inch (3.96mm) pitch. The connector utilizes female contacts made of copper alloy with gold plating, specifically the half-beryllium-copper type. It supports PCB thicknesses ranging from 0.054 to 0.070 inches. The unit employs a solder pin termination method and includes flanges for panel mounting. The housing is constructed from green thermoplastic polyester, ensuring durability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 34 contact positions for high-density interconnects
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Panel-mount design with integrated flanges for secure mechanical installation
• Thermoplastic polyester insulation offers stability within specified thermal limits

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 34-position count and dual-row layout before procurement. Confirm compatibility with the target PCB thickness range of 0.054 to 0.070 inches to ensure proper engagement. Check for RoHS compliance requirements if the application demands environmental standards. Ensure storage conditions prevent moisture damage prior to soldering, although MSL classification may not apply. Validate that the gold plating specification meets the conductivity needs of the circuit.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96mm pitch is required for robust mechanical connection. Consider the panel-mount flange feature if space constraints allow for external securing rather than board-only retention. Evaluate the operating temperature range against the environmental conditions of the final assembly. Compare contact material specifications to ensure adequate current carrying capacity for the intended load. Verify that the solder termination type aligns with the manufacturing process capabilities.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts and mounting options to accommodate different form factors. Components in this line are engineered for durability and consistent electrical performance in demanding environments. The 305 series provides a standardized solution for edgeboard applications requiring reliable interconnectivity.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-020-556-202 or 305-050-556-202 if position count adjustments are necessary. Ensure any substitute maintains the same 0.156-inch pitch and dual-row configuration. Verify that alternative parts support the same PCB thickness and mounting style to preserve mechanical integrity.
