305-048-520-558

Edgeboard Connectors Overview

The EDAC Inc. 305-048-520-558 is a standard card edge connector header from the 305 series, designed for panel mount applications with a vertical orientation. It features 48 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector utilizes gold-plated copper alloy contacts with a solder pin termination type. It is engineered to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The unit provides a continuous current rating of 5 A and supports an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides high voltage isolation capability rated at 1800VACrms

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control hardware requiring polarized card edge interfaces
• High-density signal routing in vertical mounting configurations

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarization keys and board thickness tolerances. Confirm that the thermal operating range of -40°C to +105°C aligns with the environmental conditions of the target assembly. Ensure the solder pin termination method matches the PCB fabrication capabilities available for the production run.

Edgeboard Connectors Selection Notes

Select this component when a dual-row header with a 3.96 mm pitch is required for panel-mount installations. The 48-position count suits applications needing substantial I/O density within a constrained footprint. Verify that the 1.57 mm board thickness specification matches the design constraints of the mating card edge module to ensure proper mechanical engagement and electrical continuity.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their robust construction and versatile mounting options. The series supports various position counts and termination styles, catering to diverse industrial and commercial electronics needs. The 305-048-520-558 variant specifically addresses requirements for high-current capacity and reliable vertical interconnection in panel-based architectures.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-048-500-558 or 305-048-520-502 if different housing colors or minor packaging distinctions are acceptable. Ensure any substitute maintains the identical 3.96 mm pitch, 48-position count, and 1.57 mm board thickness tolerance to preserve mechanical fit.
