305-052-555-268

Edgeboard Connectors Overview

The EDAC Inc. 305-052-555-268 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 52 positions arranged in two rows 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). It utilizes female contacts made of copper alloy with gold plating, rated for 5 A current at an insulation resistance of 5 GOhms. The thermoplastic housing supports panel mounting in a vertical orientation, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodating non-specified PCB types
• Low-profile insulator body constructed from thermoplastic material
• Gold-plated copper alloy contacts ensuring reliable electrical performance
• Vertical panel mount configuration with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation with high-density signal routing
• Automotive electronics modules needing durable connection solutions

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official catalog to ensure compatibility with required PCB thicknesses and mounting styles. Confirm that the gold plating specification meets the environmental requirements for your application. Cross-reference the 52-position count and dual-row layout with your mechanical design constraints. Ensure the vertical panel mount style aligns with your enclosure specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector is required for 1.57 mm thick PCBs. The 3.96 mm pitch suits applications needing moderate density without excessive height. Verify that the 5 A current rating and 5 GOhm insulation resistance meet system safety standards. Consider the vertical panel mount style if space constraints favor this orientation over horizontal surface mount alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting options to accommodate different board designs. The 305-052 variant specifically provides 52 connections, balancing density with manageable form factor. It represents a mature product line known for reliability in harsh environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 52 positions and 3.96 mm pitch, such as 305-050-556-502 or 305-040-520-268, provided they meet the same mechanical and electrical criteria. Verify that any replacement maintains the dual-edge female configuration and vertical panel mount style to ensure interchangeability.
