305-032-556-501

Edgeboard Connectors Overview

The EDAC Inc. 305-032-556-501 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 32 positions arranged in a dual-row configuration 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). Contacts are made of copper alloy with gold plating, rated for 5 A current. The insulator body is green thermoplastic, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodates double-sided PCBs
• Low-profile insulator body constructed from green thermoplastic material
• Gold-plated copper alloy contacts ensure reliable electrical performance
• Panel mount installation style provides secure vertical positioning

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing high-density signal routing
• Automotive electronics modules demanding reliable thermal stability

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and row configuration before ordering. Confirm that the PCB thickness aligns with the 1.57 mm specification to ensure proper insertion force and retention. Check for any updated RoHS compliance documentation if environmental regulations apply to your region. Ensure that the gold plating specification meets the corrosion resistance requirements for your intended environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is necessary for double-sided circuit boards. The 3.96 mm pitch offers a balance between density and ease of manufacturing. Consider the vertical panel mount style if space constraints require a perpendicular interface. Verify that the 5 A current rating suffices for the power distribution needs of the application without excessive heating.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors for various electronic assemblies. The series is known for its versatility in handling different board thicknesses and contact configurations. The 305-032-556-501 variant specifically addresses the need for 32-position dual-row connectivity in compact form factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variations with different position counts or plating options. Cross-referencing with other manufacturers requires verifying identical pitch, row spacing, and board thickness compatibility. Ensure that any replacement maintains the same mounting style and electrical ratings to preserve system integrity.
