305-044-521-512

Edgeboard Connectors Overview

The EDAC Inc. 305-044-521-512 is a standard card edge connector featuring 44 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accepts board thicknesses ranging from 1.37 mm to 1.78 mm. The component employs gold-plated copper alloy contacts with a solder pin termination type for secure electrical connection. Designed for panel mount installation, it operates within a temperature range of -40°C to +105°C and supports a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced alignment
• Features a thermoplastic polyester housing with green coloration
• Provides high dielectric strength with an 1800 VACrms rating

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Telecommunications equipment utilizing standardized card edge interfaces
• Test and measurement instrumentation needing reliable signal transmission

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarizing key configurations and contact plating specifications. Confirm that the thermal rating aligns with the operational environment of the target application. Cross-reference the package dimensions with the host PCB layout to guarantee proper fit during panel mounting procedures.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with a 3.96 mm pitch is required for vertical panel mounting applications. Ensure the host circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to maintain optimal contact engagement. Consider the 5 A current rating and 1800 VACrms insulation capability when designing circuits that demand high reliability under varying environmental conditions.
