305-042-555-208

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-208 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual row configuration with 42 positions and a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Utilizes gold-plated copper alloy contacts with half-beam spring design
• Features a low-profile thermoplastic insulator body for compact integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement devices needing high-reliability signal connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct termination style and plating thickness. Confirm that the required PCB thickness falls within the specified tolerance range for reliable contact engagement. Check RoHS compliance status directly with the manufacturer or authorized distributors prior to ordering.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 42-position interface is required for vertical panel mounting. Ensure the application environment stays within the -40°C to +105°C operational limits. Verify that the mating card edge thickness matches the 1.57 mm nominal specification to guarantee proper electrical contact and mechanical stability during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent 3.96 mm spacing. These connectors are engineered for durability in demanding environments, providing stable electrical performance through gold-plated contacts and robust thermoplastic housings.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-042-520-202 for similar form factors. Verify that any substitute maintains identical pin count, pitch, and mounting style requirements.
