305-042-521-212

Edgeboard Connectors Overview

The EDAC 305-042-521-212 is a standard card edge connector featuring 42 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for .062 inch (1.57 mm) nominal thickness printed circuit boards, this female header employs straight solder pin terminals for panel mount installation. The unit incorporates a green thermoplastic polyester insulator body and gold-plated copper alloy contacts to ensure reliable electrical performance.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body design for compact integration
• Provides a 5A continuous current rating with high dielectric strength

Edgeboard Connectors Applications

• High-density electronic interconnect systems
• Industrial control panel mounting
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm terminal configuration and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm prior to procurement. Confirm that the selected variant matches the required polarizing key acceptance capabilities for the intended assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 3.96 mm pitch is required for 1.57 mm thick circuit boards. The 5A current rating supports moderate power distribution needs. Verify that the panel mount style aligns with the mechanical enclosure design and that the straight terminal orientation fits the available vertical clearance within the system chassis.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by robust thermoplastic polyester construction and versatile mounting options. Components in this family are engineered for durability in demanding environments, offering consistent electrical connectivity through precise contact geometry and standardized dimensional tolerances.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 305 series that share identical 42-position counts and 3.96 mm spacing. Ensure any substitute maintains the same 1.57 mm board thickness tolerance and panel mount configuration to preserve mechanical fit and electrical continuity.
