305-038-521-207

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-207 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 38 positions arranged in a dual-row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. The unit utilizes a solder pin termination type for secure board attachment.

Edgeboard Connectors Feature Summary

• Dual-row header design accommodating non-specified dual-edge cards
• Gold-plated copper alloy contacts for corrosion resistance
• Thermoplastic insulator body rated for -40°C to +105°C operation

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact contact length, flange style, and insulation color variations. Ensure compatibility with the target PCB thickness tolerance of 1.37mm to 1.78mm. Confirm RoHS compliance status through official documentation prior to integration into regulated assemblies.

Edgeboard Connectors Selection Notes

Select this component when a 38-position dual-row interface is required for vertical panel mounting. The 3.96 mm pitch suits standard half-inch grid layouts. Verify that the gold contact plating meets the environmental requirements for the intended operating temperature range and cycle life expectations compared to alternative tin or silver finishes.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for robust mechanical performance. The series offers various position counts and row configurations to support diverse modular electronics architectures. The 305-038 variant specifically addresses mid-density connection needs within industrial and commercial hardware designs requiring durable edge-card interfaces.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 3.96 mm pitch and 38-position count, such as 305-038-520-207 or 305-038-521-507, while verifying differences in insulation color and flange specifications.
