305-044-500-258

Edgeboard Connectors Overview

The EDAC Inc. 305-044-500-258 is a standard card edge connector from the 305 Series, designed for panel mounting applications. It features a dual female configuration with 44 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts PCB thicknesses ranging from 1.37 mm to 1.78 mm. Contacts are constructed from copper alloy with gold plating, ensuring reliable signal transmission. The unit supports a continuous current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for non-specified card edge interfaces
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Panel mount installation style with vertical orientation
• Accepts between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 44-position count and 3.96 mm pitch before integration. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Ensure the application environment remains within the specified operating temperature limits of -40°C to +105°C. Check for RoHS compliance requirements if applicable to the final assembly standards.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-current card edge solution is required for panel-mounted systems. The 5 A rating and gold contacts make it suitable for demanding industrial environments. Consider the dual-row layout and polarizing key acceptance if mechanical alignment and signal integrity are critical design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which provides standardized card edge connectors with various position counts and mounting options. The series is characterized by its durable thermoplastic housing and consistent 3.96 mm spacing, widely used in sectors requiring reliable board-to-board or board-to-panel connections.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 Series variants such as 305-044-500-202 or 305-044-500-503, provided they match the 44-position count and dual female configuration. Verify that alternative parts maintain the same 3.96 mm pitch and panel mount specifications.
