305-062-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-062-556-203 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 62 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector accepts PCBs with thicknesses between 1.37 mm and 1.78 mm. Electrical specifications include a 5 A current rating and an insulation resistance of 5 GOhms. 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 retention
• Utilizes gold-plated copper alloy contacts for reliable signal transmission
• Features a thermoplastic polyester insulator for environmental stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted connections
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement devices needing high-density dual-row connectivity

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarizing key configurations and mounting styles. Confirm that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement and electrical performance.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for panel installation. Ensure the application environment stays within the -40°C to +105°C operating temperature range. Verify that the system design accommodates the necessary polarizing key slots for board alignment and retention 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 while maintaining consistent 3.96 mm spacing and 5 A current ratings. These connectors are engineered for durability in demanding industrial environments, providing stable interconnect solutions for double-sided edge cards.

Edgeboard Connectors Replacement Considerations

Cross-reference the 305-062-556-203 with other EDAC 305 series variants having identical 62-position dual-row layouts. Verify that any substitute maintains the same 3.96 mm pitch, panel mount style, and compatible polarizing key requirements to ensure mechanical and electrical interchangeability.
