307-040-456-203

Edgeboard Connectors Overview

The EDAC Inc. model 307-040-456-203 is a standard card edge connector designed for panel mount applications. It features a dual female configuration with 40 positions arranged in two rows. The contact spacing is 3.96 mm (0.156 inches), and the row spacing is 5.08 mm (0.200 inches). The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are tin-plated, and the insulator body is green thermoplastic polyester. It operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating double-sided PCBs
• Panel mount installation with flush mount flange and floating bobbin feature
• Low-profile insulator body constructed from green thermoplastic polyester

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation panels

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm plating type and mounting style. Ensure the target PCB thickness matches the 1.57 mm specification. Confirm that the tin-plated contacts meet the environmental requirements for the intended application environment. Cross-reference the part number with official EDAC documentation to validate current availability status.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection is required for a 40-position interface. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm connectors. The panel mount style with a floating bobbin helps manage alignment tolerances during insertion. Consider the operating temperature range and material compatibility with the host enclosure.

Edgeboard Connectors Part Context

This part belongs to the EDAC 307 series of card edge connectors. The series offers various configurations including single and dual rows with different mounting options. These connectors are engineered for reliable performance in demanding environments, providing secure electrical connections between edge cards and backplanes or chassis-mounted headers.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 40 position count, 3.96 mm pitch, dual-row layout, and panel mount form factor. Verify that any alternative maintains the same 1.57 mm board thickness acceptance and similar thermal ratings.
