305-084-555-507

Edgeboard Connectors Overview

The EDAC Inc. 305-084-555-507 is a standard card edge connector designed for panel mounting applications. It features an 84-position dual-row female configuration 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). Electrical specifications include a continuous current rating of 5 A and a dielectric withstand voltage of 1800 VACrms. The contacts are constructed from copper alloy with gold plating, housed in a green thermoplastic insulator body.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board retention
• Features a low-profile insulator body design for compact integration
• Utilizes gold-plated copper alloy contacts to ensure reliable signal transmission

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring high-density interconnects
• Industrial control systems utilizing dual-edge card edge PCBs
• Equipment needing polarized keying options for board orientation

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm mechanical dimensions and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the required polarizing key type matches the connector's acceptance specifications. Cross-reference the RoHS status with current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 84 positions is required for panel-mount installations. The 3.96 mm pitch suits applications needing robust connections for thicker PCBs. Consider the 5 A current rating for power distribution needs. Evaluate the availability of compatible polarizing keys if board locking is necessary for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations. The 305-084 variant specifically provides a high-density solution for dual-edge cards. The numbering system indicates position count, row configuration, and housing characteristics within the EDAC product line.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for alternative part numbers with different position counts or termination styles. Verify that any substitute maintains the 3.96 mm pitch and 1.57 mm board thickness compatibility. Ensure electrical ratings meet or exceed the original 5 A and 1800 VACrms specifications.
