305-066-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-066-500-203 is a standard card edge connector from the 305 Series, designed for dual female connections with 66 positions. It features a 0.156-inch (3.96 mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm). The connector provides a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. Gold-plated copper alloy contacts ensure reliable performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Dual female configuration with gold-plated copper alloy contacts
• Thermoplastic polyester insulation housing

Edgeboard Connectors Applications

• Industrial control systems requiring polarized card edge interfaces
• High-density electronic modules needing 66-position connectivity
• Equipment operating in environments up to 105°C

Edgeboard Connectors Procurement Notes

Verify that the specific application requires polarizing key compatibility, as this component supports both between-contact and in-contact types. Confirm the host PCB thickness falls strictly within the 1.37 mm to 1.78 mm specification range to ensure proper mechanical engagement. Ensure the design accommodates the 0.156-inch pitch without deviation.

Edgeboard Connectors Selection Notes

Select this model when a high-pin-count, dual-row female connector is required for panel or vertical mounting applications. The 305 series offers robust electrical ratings suitable for demanding industrial conditions. Consider the physical dimensions and polarizing key requirements during the initial layout phase to avoid integration issues.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series of standard card edge connectors. The series is characterized by its durable construction and versatile positioning options. The 305-066-500-203 variant specifically addresses high-density interconnect needs with its 66-position capacity and standardized 3.96 mm spacing.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series parts with matching pin counts and pitch specifications. Verify that any alternative maintains the same 5A current rating and 1800VACrms dielectric strength. Ensure the replacement also supports the required polarizing key configurations.
