305-066-521-268

Edgeboard Connectors Overview

The EDAC Inc. 305-066-521-268 is a standard card edge connector from the 305 series, designed for dual female mating with non-specified double-sided cards. It features 66 positions arranged in two rows with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating and a green thermoplastic insulator body, it supports panel mounting in a vertical orientation. The unit utilizes solder lug termination and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Low profile insulator body constructed from green thermoplastic material
• Gold-plated copper alloy contacts ensure reliable electrical connectivity
• Vertical panel mount design with solder lug termination for secure installation

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Medical interconnect solutions demanding durable connector performance
• Agricultural technology equipment operating in harsh environments
• General electronic assemblies utilizing standard double-sided card edge modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm exact mechanical dimensions and termination style. Confirm RoHS compliance status directly with the supplier or datasheet documentation prior to integration. Ensure that the target printed circuit board thickness aligns with the specified 0.062-inch nominal requirement for proper insertion force and retention. Cross-reference the part number with current distributor availability as supply chain constraints may affect immediate procurement timelines.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection is required for double-sided card edge applications within the 305 series family. The 0.156-inch pitch allows for substantial signal routing density while maintaining mechanical stability. Consider the vertical panel mount style if space constraints require a perpendicular interface relative to the chassis. Verify that the 5-ampere current rating per contact meets the system's power distribution requirements. Evaluate the operating temperature range to ensure compatibility with the environmental conditions of the final assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely utilized across various industrial and commercial sectors. The series offers a range of position counts and configurations to suit different board sizes. The 305-066 variant specifically addresses applications needing a higher pin count within the standard 3.96 mm pitch format. It shares common design principles with other parts in the series, such as consistent insulation materials and contact plating standards, ensuring interchangeability in broader system designs where specific pin counts differ.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include EDAC part numbers with identical pitch and row spacing but differing position counts, such as 305-064-521-268 or 305-068-521-268. Verify that any alternative part maintains the same 0.140-inch row spacing and 0.062-inch board thickness acceptance. Ensure that the replacement retains the dual female contact type and gold plating specification to match electrical and mechanical performance requirements.
