305-028-555-207

Edgeboard Connectors Overview

The EDAC Inc. 305-028-555-207 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 28 positions arranged in a dual-row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are constructed from copper alloy and feature gold plating on the mating area, while tails utilize tin plating over nickel underplating for soldering. The unit has a current rating of 5 amps and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified double-sided PCBs

• Low-profile insulator body facilitates compact panel integration
• Solder lug termination provides secure board attachment

Edgeboard Connectors Applications

• Industrial control system interface modules
• Telecommunications equipment backplanes
• Test and measurement instrument cards
• Embedded computing subsystem connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm plating specifications and material composition. Ensure compatibility with the target PCB thickness tolerance of 1.57 mm nominal. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 28-position count with the intended circuit density needs.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm pitch is required for vertical panel mounting. The 5-amp current rating suits moderate power distribution applications. Verify that the green thermoplastic insulator meets environmental standards for the operating temperature range. Ensure the solder lug termination method matches the assembly process capabilities.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and row configurations to support diverse interconnect needs. The 305-028 variant specifically addresses applications requiring 28 connection points in a dual-row format.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 305-028-520-207 and 305-028-555-208, provided they match the required pin count and termination style. Verify that alternative parts maintain the same 3.96 mm pitch and 1.57 mm board thickness acceptance criteria before implementation.
