305-040-500-503

Edgeboard Connectors Overview

The EDAC Inc. part number 305-040-500-503 is a standard card edge connector from the 305 Series, designed for dual female connections with 40 positions. It features a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with a green thermoplastic insulator body, it utilizes gold-plated copper alloy contacts to ensure reliable signal transmission.

Edgeboard Connectors Feature Summary

• Dual female configuration for secure board insertion
• Low profile insulator body design
• Gold-plated copper alloy contacts for conductivity

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies
• Industrial control system interfaces
• Communication equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 0.062 inches (1.57 mm) before integration. Confirm that the panel mounting style aligns with the mechanical constraints of the final enclosure design.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface is required for vertical panel mounting. The 0.156-inch pitch suits applications needing robust connectivity without excessive density. Verify that the operating temperature range meets environmental requirements and that the solder lug termination method matches the assembly process capabilities.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which specializes in standard card edge connectors for industrial and commercial electronics. The series offers various position counts and mounting styles, providing flexibility for different board sizes and structural needs within complex electronic systems requiring durable interconnections.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 Series variants sharing the same 40-position count and 0.156-inch pitch. Ensure any substitute maintains identical row spacing and PCB thickness acceptance to guarantee mechanical fit and electrical continuity without redesigning the host panel.
