305-082-520-578

Edgeboard Connectors Overview

The EDAC Inc. 305-082-520-578 is a standard card edge connector from the 305 series, designed for panel mount applications with vertical orientation. It features 82 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic housing, supporting a continuous current rating of 5 A. It accepts PCB thicknesses between 1.37 mm and 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Provides 1800VACrms dielectric voltage capability
• Features half-beam contact type for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment board connections
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify RoHS3 compliance status and REACH restrictions before procurement. Confirm that the specific suffix 578 corresponds to the required packaging quantity and lead time parameters. Ensure compatibility with existing panel mounting hardware and verify that the 82-position dual-row format matches the target PCB layout specifications exactly.

Edgeboard Connectors Selection Notes

Select this model when a dual-row card edge interface with 82 positions is required. The 3.96 mm pitch and 5 A current rating suit moderate power applications. Consider the vertical panel mount style for chassis integration. Verify that the operating temperature range meets environmental requirements and that polarizing key options are necessary for the assembly process.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and housing materials. The 305-082-520-578 specifically denotes an 82-position variant with gold plating and thermoplastic insulation, designed for robust industrial and commercial electronic interconnections.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants for position count differences. Verify mechanical dimensions against competitors like Amphenol or Molex if sourcing alternatives. Ensure pinout and polarizing key compatibility remain unchanged during substitution.
