305-046-556-568

Edgeboard Connectors Overview

The EDAC Inc. 305-046-556-568 is a standard card edge connector from the 305 Series, designed for dual-row applications with 46 positions. It features a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and supports a continuous current rating of 5 A. Constructed with a thermoplastic insulator body, it operates within a temperature range of -40°C to +105°C and provides an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body with vertical panel mounting style
• Utilizes half-beam contact type for robust connection stability

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge connections
• Panel-mounted electronic modules needing secure dual-row interfaces
• Equipment utilizing standardized 0.062 inch thick PCBs

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm compatibility with required polarizing key configurations and mounting hardware. Ensure that the selected variant matches the intended PCB thickness tolerance of 1.57 mm. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and compliance with RoHS3 specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with polarizing key capability is required for panel-mount applications. The 3.96 mm pitch accommodates standard board layouts while the 5 A current rating suits moderate power distribution needs. Consider the vertical mounting orientation and thermoplastic housing material for environmental durability within the specified operating temperature range.
