307-040-520-207

Edgeboard Connectors Overview

The EDAC Inc. 307-040-520-207 is a standard card edge connector from the 307 series, designed for dual-edge board applications. It features 40 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.200 inches (5.08 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating and a thermoplastic polyester insulator, it supports a current rating of 5 A and an insulation resistance of 5 GOhms. Operating within a temperature range of -40°C to +105°C, this receptacle utilizes a straight PCB mount style with solder termination.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodates non-specified dual-edge cards
• Low profile insulator body constructed from thermoplastic polyester
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Straight PCB mount configuration with solder termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard board thicknesses
• Test and measurement instrumentation needing high-density connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact termination type, plating thickness, and mounting variations. Ensure the application environment remains within the specified -40°C to +105°C operating range. Confirm that the target PCB thickness aligns with the 1.57 mm nominal requirement for proper mechanical engagement. Cross-reference the 40-position count with schematic requirements to prevent pinout mismatches during integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 40 positions is required. The 3.96 mm pitch and 5.08 mm row spacing define the footprint constraints. Consider the straight mount orientation for vertical insertion into panel or chassis openings. The 5 A current rating per contact dictates suitability for moderate power distribution alongside signal lines. Verify compatibility with existing tooling for the specified board thickness.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 series of standard card edge connectors. The series offers various position counts and mounting styles tailored for diverse electronic assembly needs. Components in this family share common design principles, including low-profile bodies and standardized spacing metrics. The 307-040-520-207 specifically addresses applications requiring a 40-position dual-edge receptacle with gold-plated contacts for enhanced durability.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 307/357 Ordering Guide for direct substitutes with differing position counts or termination styles. Verify dimensional compatibility before swapping parts, as row spacing and board thickness tolerances are critical. No alternative manufacturer part numbers are confirmed in public documentation.
