305-066-521-508

Edgeboard Connectors Overview

The EDAC Inc. 305-066-521-508 is a dual-edge board connector designed for high-density applications. It features 66 positions with a 0.156-inch (3.96mm) pin spacing and two rows of contacts. The connector utilizes female half-beam contacts with gold plating over copper alloy substrates. It supports PCB thicknesses ranging from 0.054 to 0.070 inches. The unit operates within a temperature range of -40°C to 105°C and employs thermoplastic polyester insulation.

Edgeboard Connectors Feature Summary

• Dual-edge configuration provides robust mechanical stability for edge-board insertion
• Gold-plated half-beam contacts ensure reliable signal transmission and low contact resistance
• Thermoplastic polyester insulation offers durability across wide thermal operating ranges

Edgeboard Connectors Applications

• Industrial control systems requiring stable interconnects
• Communication equipment backplanes
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm compatibility with target PCB layouts. Ensure that the required contact count and pitch align with design specifications before procurement. Cross-reference environmental compliance data such as RoHS status directly with the supplier's certified datasheets to meet regulatory requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface with 66 positions is required. Confirm that the mating card thickness falls within the specified operational limits. Evaluate the need for through-hole termination versus surface mount alternatives based on assembly constraints. Verify that the 0.156-inch pitch matches the existing system architecture.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in edgeboard connectors for demanding environments. The series offers various position counts and mounting options. This specific model represents a standard dual-edge solution suitable for general-purpose industrial and commercial electronic assemblies requiring durable connections.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for compatible alternatives. Verify that any substitute maintains identical pin count, pitch, and termination style. Ensure mechanical dimensions match the existing footprint to avoid rework.
