305-046-556-204

Edgeboard Connectors Overview

The EDAC Inc. 305-046-556-204 is a standard card edge connector from the 305 series, designed for dual-side contact applications. It features 46 positions with a 3.96 mm (0.156 inch) pitch and accommodates a printed circuit board thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts and solder pin termination for secure electrical connection. Rated for 5 A current, it employs a thermoplastic insulator body and supports vertical panel mounting. Operating within a temperature range of -40°C to +105°C, this component ensures reliable performance in industrial environments.

• Flush mount flange with top opening for secure panel installation

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with required PCB thickness and mounting style. Ensure that the gold plating specification meets the environmental requirements for the intended application. Cross-reference the 46-position count and 3.96 mm pitch with design schematics to prevent interface mismatches during integration.

Edgeboard Connectors Selection Notes

Select this model when a dual-row card edge connector with a 3.96 mm pitch is required for panel-mounted applications. The 46-position capacity suits moderate-density interconnect needs. Consider the 5 A rating and wide operating temperature range for reliability in demanding conditions. Verify that the flush mount flange design aligns with the mechanical constraints of the enclosure.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems.
