305-074-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-074-521-502 is a dual-row card edge connector designed for vertical panel mounting. It features 74 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The connector utilizes gold-plated contacts to ensure reliable signal transmission and includes provisions for between-contact and in-contact polarizing keys. Rated for 5A continuous current and 1800VACrms, it 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 board alignment
• Features a low-profile insulator body for compact installation requirements
• Provides high voltage insulation capability rated at 1800VACrms
• Supports standard 0.062-inch nominal thickness PCBs

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing standardized card edge interfaces
• Automotive electronics demanding high voltage isolation and reliability
• Test and measurement instrumentation needing precise board alignment

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact pin count, contact plating specifications, and flange configuration. Ensure that the required polarizing key type matches the connector's acceptance capabilities. Confirm compliance with RoHS3 standards and check for any regional distribution restrictions or supply limitations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 0.156-inch pitch is required for 0.062-inch thick boards. The 5A current rating and 1800VACrms insulation make it suitable for applications exceeding standard low-power limits. Consider the availability of polarizing keys if precise board positioning is critical 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 mounting styles, all sharing common electrical ratings and mechanical dimensions. The 305 series is widely used in industrial and commercial applications where reliable, high-density connections are necessary.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include parts with identical pitch and row configurations, such as the 305-074-521-512. Verify that alternative part numbers match the 74-position count and 0.156-inch spacing to ensure mechanical fit and electrical compatibility.
