305-024-521-208

Edgeboard Connectors Overview

The EDAC Inc. 305-024-521-208 is a standard card edge connector from the 305 series, designed for vertical panel mounting applications. It features a dual female configuration with 24 positions and a contact spacing of 0.156 inches (3.96 mm). The connector accommodates printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm) and utilizes a row spacing of 0.140 inches (3.56 mm). Constructed with copper alloy contacts that are gold-plated, this component provides a continuous current rating of 5 amperes and supports an insulation resistance voltage of 1800VACrms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body suitable for compact panel installations
• Utilizes gold-plated copper alloy contacts to ensure reliable signal transmission

Edgeboard Connectors Applications

• Vertical panel-mounted electronic assemblies requiring dual-sided card edge access
• Industrial control systems utilizing standardized 0.156-inch pitch interconnects
• Equipment needing polarized keying options for precise PCB insertion

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness of 0.062 inches before procurement. Confirm availability status as distribution channels may vary by region. Cross-reference the 24-position count and dual female termination type with system design requirements to prevent interface mismatches during integration.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-sided card edge connections. The 0.156-inch pitch and 0.140-inch row spacing define the mechanical envelope for the host system. Consider the 5A current rating and 1800VACrms insulation capability for electrical safety margins. The availability of polarizing key options makes it suitable for applications demanding strict orientation control during assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for robust industrial and commercial interconnect needs. The series offers various position counts and mounting styles, with the 305-024-521-208 specifically providing a 24-position dual female configuration. It shares common design principles with other 305 series parts, such as consistent pitch and material standards, while differing in terminal count and specific housing variations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 305-048-521-208, which shares identical mechanical and electrical characteristics but offers 48 positions instead of 24. When replacing, verify that the new part matches the 0.156-inch pitch and vertical mounting style. Ensure the replacement maintains the dual female contact configuration and compatible polarizing key acceptance capabilities.
