305-016-556-501

Edgeboard Connectors Overview

The EDAC Inc. 305-016-556-501 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features a dual-row configuration with 16 positions and a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and utilizes gold-plated phosphor bronze contacts to ensure low contact resistance and durability. Rated for 5 A continuous current, it supports operation within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts polarizing keys between or within contacts for secure board alignment
• Features a low-profile thermoplastic insulator body for compact panel mounting
• Utilizes gold-plated phosphor bronze contacts for enhanced conductivity and corrosion resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized module connections
• Test and measurement instrumentation panels

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required row count and position quantity before procurement. Confirm that the target PCB thickness aligns with the 0.062-inch specification to ensure proper mechanical retention. Check for RoHS compliance documentation if environmental regulations apply to the assembly. Ensure that the mating card edge conductor width corresponds to the connector's contact pitch for optimal electrical engagement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 16 positions is required for vertical panel mounting. Consider the 5 A current rating and 1800 VACrms insulation voltage for appropriate electrical isolation. Evaluate the need for polarizing key compatibility if precise board orientation is critical. Compare against other series connectors if different contact spacings or board thicknesses are necessary for the design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standard card edge solutions for various electronic applications. The series offers multiple position counts and row configurations to accommodate diverse design requirements. Components in this family typically feature thermoplastic insulators and gold-plated contacts for reliable performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include the 305-016-556-508 and 305-016-520-501, which share identical physical dimensions and electrical characteristics. Verify that any replacement maintains the same 0.156-inch pitch and dual-row layout to ensure interchangeability without modifying the host PCB.
