305-054-556-512

Edgeboard Connectors Overview

The EDAC Inc. 305-054-556-512 is a standard card edge connector from the 305 series, designed for dual-row applications with 54 positions. It features a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester insulator body. Rated for 5 A continuous current, it supports straddle mount installation with vertical orientation.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for board-to-board or backplane interconnection
• Gold-plated contacts ensure reliable signal transmission in demanding environments
• Thermoplastic polyester housing provides structural stability and thermal resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Telecommunications equipment interface modules
• Automotive electronic control unit interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and insulation color specifications. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the straddle mount style aligns with the mechanical assembly requirements. Check RoHS compliance status against current regulatory standards for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required. The 54-position count suits applications needing moderate I/O density. The 5 A current rating supports standard power distribution needs. Verify that the vertical mounting angle fits within the enclosure height constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and row configurations. The series is characterized by its .156 inch contact spacing and acceptance of standard .062 inch thick PCBs. It serves as a reliable interconnect solution for industrial and commercial electronics where durability is essential.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing the same 3.96 mm pitch and 54-position count. Verify mechanical footprint and pinout compatibility before substitution. Ensure equivalent current ratings and material specifications are maintained.
