305-048-520-268

Edgeboard Connectors Overview

The EDAC Inc. 305-048-520-268 is a standard card edge connector 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 accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission, rated for 5 A current. The insulator body is made of green thermoplastic polyester, supporting an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided card edge PCBs for high-density interconnects.
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance over time.
• Low-profile thermoplastic insulator body facilitates compact panel mounting in vertical configurations.
• Solder pin termination method ensures secure mechanical attachment to the host panel or chassis.

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interface connections
• Telecommunications equipment utilizing standardized card edge module architectures
• Test and measurement instrumentation needing reliable high-current signal pathways

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact plating thickness and insulator color specifications. Confirm compatibility with the target PCB thickness tolerance of 1.37 mm to 1.78 mm. Ensure the panel cutout dimensions align with the connector's physical footprint for proper vertical installation. Check RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 48-position connection is required for double-sided card edge modules. The 3.96 mm pitch suits applications where board density is moderate but mechanical stability is critical. Consider the 5 A current rating for power distribution needs within the specified temperature range. Verify that the solder pin termination fits the available panel mounting holes.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their durable construction and versatile mounting options. The series offers various position counts and row configurations to support different interface requirements. Components in this line typically utilize thermoplastic insulators and gold-plated contacts to maintain performance in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical positioning and pitch, such as 305-048-500-201, provided the housing color and specific suffix variations meet the design requirements. Cross-series replacements require careful verification of mechanical dimensions and electrical ratings to ensure functional equivalence without modifying the host panel structure.
