305-018-556-501

Edgeboard Connectors Overview

The EDAC Inc. 305-018-556-501 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features an 18-position dual-row configuration with a 3.96 mm (0.156 inch) pitch and 3.56 mm row spacing. The connector accepts PCBs with a nominal thickness of 1.57 mm. Contacts are made of copper alloy with gold plating, providing a 5 A continuous current rating and 1800 VACrms insulation voltage. The housing is constructed from thermoplastic material, ensuring reliable performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for high-density interconnects
• Accepts between-contact and in-contact polarizing keys for secure alignment
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Thermoplastic housing provides structural integrity and electrical insulation

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring vertical card edge interfaces
• Industrial control systems utilizing modular circuit boards
• Telecommunications equipment with standardized card form factors

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to confirm exact pin count, termination style, and mounting variations. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the required polarizing key type matches the connector's acceptance specifications before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 18-position interface is required for vertical panel mounting. Confirm that the application environment stays within the specified -40°C to +105°C temperature range. Verify that the mating card edge thickness aligns with the 1.57 mm nominal specification to ensure proper mechanical engagement and electrical contact.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which offers various mounting options and configurations for standard card edge applications. The series supports different position counts and termination styles, allowing for flexible integration into diverse electronic systems while maintaining consistent 3.96 mm pitch standards across the family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series variants such as 305-018-556-504 or 305-018-555-508 for alternative termination types like solder lugs. Ensure any substitute maintains the same 18-position count, dual-row layout, and 3.96 mm pitch to guarantee mechanical and electrical compatibility.
