305-052-500-208

Edgeboard Connectors Overview

The EDAC Inc. 305-052-500-208 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 52 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 made of copper alloy with gold plating, rated for 5 A current. The insulator body is green thermoplastic, providing an insulation resistance of 5 GOhms and operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual row female connector design accepting 0.062 inch thick PCBs
• Gold-plated copper alloy contacts for reliable signal transmission
• Low profile thermoplastic insulator body in green color
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing high-density signal routing
• Computer peripheral hardware interfacing via dual-row connectors

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact termination type and material specifications, as variations exist within the 305 series. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm that the gold plating meets the required corrosion resistance standards for the intended operational environment. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity and traceability of the component batch.

Edgeboard Connectors Selection Notes

Select this model when a dual-row connection with 52 positions is required for a 0.062 inch thick board. The 3.96 mm pitch suits applications needing wider spacing compared to standard 2.54 mm headers. Consider the vertical panel mount style if space constraints favor front-accessible connections. Verify that the 5 A current rating aligns with the power distribution requirements of the connected circuitry. Check environmental ratings if operation exceeds standard indoor conditions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which offers various position counts and termination options. The series is characterized by its durable thermoplastic construction and gold-plated contacts suitable for repeated mating cycles. Similar models in the series include different pin counts such as 18, 48, or 54 positions, allowing designers to scale connectivity needs while maintaining consistent mechanical and electrical interface standards across a product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include parts with identical mechanical dimensions but different termination types, such as solder lug variants. Models like 305-052-500-278 may offer alternative end-connecting methods while retaining the same form factor. Ensure any replacement matches the 52-position count, dual-row layout, and 3.96 mm pitch to maintain PCB footprint compatibility without redesigning the host board.
