305-054-500-501

Edgeboard Connectors Overview

The EDAC Inc. 305-054-500-501 is a standard card edge connector from the 305 Series, designed for dual-row female connections with 54 positions. It features a 0.156-inch (3.96 mm) pitch and accepts PCBs with a thickness of 0.156 inches. The connector utilizes gold-plated contacts on a copper alloy base to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic material, providing robust mechanical support and electrical insulation for high-density board-to-board applications.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 54-position dual-row configuration before procurement. Confirm that the receiving PCB thickness aligns with the 0.156-inch specification to ensure proper mating. Check for any regional distribution restrictions or lead time variations associated with the manufacturer's standard supply chain. Ensure compatibility with polarizing key requirements if used in constrained spaces.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 54 positions is required for vertical panel mounting or direct board insertion. The 0.156-inch pitch accommodates standard card edge designs while maintaining sufficient spacing for high-voltage isolation. Consider the 5 A current rating and 1800 VACrms dielectric strength for applications demanding robust electrical performance. Verify that the green thermoplastic housing meets environmental and thermal requirements for the intended operating conditions.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which specializes in standard card edge connectors for various electronic assemblies.
