305-056-555-501

Edgeboard Connectors Overview

The EDAC Inc. 305-056-555-501 is a standard card edge connector designed for dual-edge board insertion. It features 56 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts plated in gold, it ensures reliable electrical performance. The unit utilizes a thermoplastic insulator body and supports panel mounting at a vertical angle.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating two-sided card edges
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Low-profile insulator body constructed from thermoplastic material
• Vertical panel mounting configuration for secure installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust card interface connections
• Telecommunications equipment utilizing standard thickness PCBs
• Test and measurement instrumentation modules
• Computer peripheral interface cards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating, insulation material, and termination style match project requirements. Confirm that the target printed circuit board thickness aligns with the 1.57 mm specification to ensure proper mechanical engagement. Check regional availability as distribution status may vary by location. Ensure compliance with relevant environmental regulations such as RoHS before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for a 56-position interface. The 3.96 mm pitch suits applications needing wider spacing between signal lines. Verify that the vertical panel mount style fits the enclosure constraints. Consider the 5 A current rating for power distribution needs within the system architecture. Ensure the operating temperature range meets the environmental conditions of the deployment site.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305-056-555-501 specifically addresses the need for a high-density dual-edge interface. It complements other single-row or different pitch connectors within the broader EDAC portfolio for modular system designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 56-position count, 3.96 mm pitch, and dual-edge configuration. Verify that alternative components support the same 1.57 mm board thickness and vertical panel mounting. Cross-reference pinout assignments and current ratings to ensure functional equivalence without redesigning the host PCB layout.
