305-036-521-508

Edgeboard Connectors Overview

The EDAC Inc. 305-036-521-508 is a standard card edge connector from the 305 series, designed for panel mount and through-hole installation. It features a dual female configuration with 36 positions arranged in two rows. The connector utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses ranging from 0.054 to 0.070 inches (1.37 to 1.78 mm). Electrical specifications include a 5 A continuous current rating and an insulation resistance of 5 GOhms. The contacts are constructed from copper alloy with gold plating, ensuring reliable performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Dual female contact configuration with gold-plated copper alloy terminals
• Thermoplastic insulator housing rated for high voltage isolation

Edgeboard Connectors Applications

• Medical interconnect systems requiring reliable signal transmission
• Agricultural technology equipment operating in harsh environments
• Industrial control panels utilizing vertical card edge interfaces

Edgeboard Connectors Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official EDAC documentation. Confirm that the specific suffix matches the required pin count and termination style. Ensure compliance with RoHS3 standards if environmental regulations apply to the assembly. Check for availability constraints as supply levels may vary by region.

Edgeboard Connectors Selection Notes

Select this model when a 36-position dual-row interface is required with a 3.96 mm pitch. Verify that the host PCB thickness falls within the 1.37 to 1.78 mm acceptance window. Ensure the design accommodates the necessary polarizing key slots if mechanical alignment is critical. Confirm that the 5 A current rating meets the circuit load requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts while maintaining consistent electrical characteristics and mounting styles. The 305-036 variant specifically addresses applications needing moderate density connections with robust mechanical retention via panel mount flanges.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other 305-series models with matching pitch and row configurations. Verify that alternative part numbers maintain the same 3.96 mm spacing and dual female contact type to ensure mechanical compatibility.
