305-082-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-082-520-203 is a standard card edge connector from the 305 Series, designed for panel mount applications with a vertical orientation. It features a dual female configuration with 82 positions and a 0.156-inch (3.96 mm) pitch. The contacts are gold-plated copper alloy with a half-beam type, rated for 5 A continuous current. The housing is green thermoplastic polyester, supporting board thicknesses between 0.054 and 0.070 inches. It utilizes solder pin termination and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure positioning
• Provides high dielectric strength with an 1800VACrms rating
• Features gold-plated half-beam contacts for reliable signal transmission
• Designed for robust panel mounting with vertical installation

Edgeboard Connectors Applications

• High-density electronic interconnect systems requiring polarized keying
• Industrial control panels needing vertical card edge connections
• Equipment utilizing double-row female connectors for signal routing
• Applications demanding high voltage isolation capabilities

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating, flange style, and insulation material compatibility. Confirm that the polarizing key requirements match the system design, as this series supports both between-contact and in-contact configurations. Cross-reference the thermal rating and current capacity with the intended operational environment to guarantee long-term reliability under load conditions.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for panel-mounted assemblies. Ensure the mating card thickness falls within the specified 1.37 mm to 1.78 mm range. Consider the 5 A current rating and 1800VACrms insulation resistance for high-power or high-voltage applications. Verify that the vertical orientation and flange dimensions align with the mechanical enclosure constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors, which are characterized by their durable thermoplastic housings and gold-plated contacts. The series offers various position counts and flange options to accommodate different board thicknesses and mounting styles. These connectors are widely used in industrial and commercial electronics where reliable, high-density interconnections are critical for system performance and longevity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but differing flange or plating specifications, such as variations in the 305-082-xxx-xxx format. Verify that any replacement maintains the 0.156-inch pitch and dual female configuration. Check for compatibility with existing polarizing key requirements and ensure the thermal and electrical ratings meet or exceed the original design specifications.
