305-082-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-082-520-503 is a standard card edge connector from the 305 Series, designed for dual-edge board insertion. It features 82 positions 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). It utilizes gold-plated copper alloy contacts and a green thermoplastic polyester insulator body. Rated for 5 A current, it supports panel mount installation at a vertical angle with solder pin termination.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for non-specified dual-edge PCBs
• Low profile insulator body construction
• Gold-plated half-beadlock contact type
• Flange feature includes flush mounting with top opening

Edgeboard Connectors Applications

• Industrial control systems requiring high-density I/O connections
• Telecommunications equipment backplanes
• Automotive electronic modules
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and flange characteristics, as variations exist within the 305 series. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the selected variant matches the required PCB thickness tolerance of 0.054 to 0.070 inches. Cross-reference the manufacturer datasheet for exact mechanical dimensions before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge connection is required with a 3.96 mm pitch. The 82-position count suits applications needing extensive signal routing in a compact form factor. Consider the vertical panel mount style for chassis integration. Verify that the 5 A current rating meets the electrical load requirements of the target circuit design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and contact configurations. The series is characterized by its robust thermoplastic polyester housing and reliable gold-plated contacts. It serves as a standardized solution for connecting double-sided edge cards in industrial and commercial electronics environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 82 positions and 3.96 mm spacing, such as 305-082-521-503. Verify identical mechanical footprint and electrical ratings before substitution.
