305-074-500-212

Edgeboard Connectors Overview

The EDAC Inc. 305-074-500-212 is a standard card edge connector from the 305 series, designed for panel mount installation with a vertical orientation. It features 74 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. The housing is made of thermoplastic polyester, providing structural integrity and insulation.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Provides a continuous current rating of 5A and withstands 1800VACrms voltage
• Features a low-profile insulator body for compact assembly requirements

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge connections
• Telecommunications equipment utilizing standardized board interfaces
• Automotive electronics needing high-voltage isolation capabilities

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times. Confirm RoHS compliance requirements match project specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 74 positions is required for vertical panel mounting. The 3.96 mm pitch suits applications where board density allows for wider spacing. Verify that the 5A current rating meets the power distribution needs of the connected circuitry. Ensure the thermoplastic polyester housing material aligns with environmental temperature constraints up to +105°C.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and configurations to support diverse motherboard and daughterboard interconnections. The 305 series is known for its durability and consistent electrical performance across different operating conditions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical positioning and mechanical dimensions but different suffixes for minor variations. Check EDAC documentation for cross-referenced models that maintain the 74-position dual-row layout and 3.96 mm pitch.
