305-048-500-258

Edgeboard Connectors Overview

The EDAC Inc. 305-048-500-258 is a standard card edge connector from the 305 series, designed for dual-edge card applications. It features 48 positions arranged in two rows with a pitch of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts and terminates via solder eyelets. It supports panel mounting at a vertical angle and accommodates board thicknesses ranging from 1.37 mm to 1.78 mm. The housing is constructed from green thermoplastic polyester, ensuring reliable electrical performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 48 total positions for high-density interconnects
• Gold-plated copper alloy contacts ensure durable conductivity and corrosion resistance
• Solder eyelet termination provides secure mechanical attachment to printed circuit boards
• Vertical panel mount style facilitates structured system integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing dual-edge module connections
• Test and measurement instrumentation with standardized card formats
• Computing hardware components needing reliable signal transmission

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 48-position count and 3.96 mm pitch before ordering. Confirm compatibility with the target PCB's specified thickness range of 1.37 mm to 1.78 mm to ensure proper contact engagement. Ensure the panel mounting orientation aligns with the system enclosure design. Check RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer datasheet for any recent updates to the 305 series specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 48 contacts is required. The 3.96 mm pitch is suitable for applications not demanding finer line spacing. The solder eyelet termination is ideal for through-hole PCB assembly processes. Consider the vertical panel mount constraint during mechanical layout planning. The thermoplastic polyester housing offers adequate insulation for general industrial environments.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles to support diverse electronic module requirements. The 305-048 variant specifically addresses needs for moderate density connections with reliable gold-plated contact surfaces. It serves as a critical interface between modular cards and base systems.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include 305-048-500-201 and 305-048-500-504. Verify that alternative part numbers maintain the identical 48-position count and 3.96 mm pitch. Ensure the termination type and mounting style match the existing design constraints before substitution.
