305-040-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-040-556-208 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 40 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and employs a solder pin termination method.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure board insertion
• Panel mount installation style with flush mount flange features
• Gold-plated copper alloy contacts for reliable conductivity
• Thermoplastic polyester insulation for environmental stability

Edgeboard Connectors Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• Embedded computing module connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct flange and plating specifications. Confirm that the target PCB thickness aligns with the 1.57 mm nominal requirement. Check RoHS compliance status directly with the supplier or manufacturer documentation prior to procurement. Ensure panel mounting hardware compatibility with the connector's flange design.

Edgeboard Connectors Selection Notes

Select this component when a 40-position dual-row interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing robust mechanical retention without high-density constraints. Consider the 5 A current rating and -40°C to +105°C operating temperature range for suitability in industrial environments. Verify that the board thickness falls within the specified tolerance for proper contact engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their low-profile insulator bodies and versatile mounting options. The series offers various position counts and termination styles to accommodate different board edge configurations. The 305-040 variant specifically addresses mid-range connectivity needs with a balance of density and mechanical strength.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts such as 305-050-556-208 or 305-054-556-278 if position count adjustments are needed. Ensure any substitute maintains the same 3.96 mm pitch and dual-row configuration. Verify that alternative parts support the same panel mount style and PCB thickness requirements.
