305-084-555-207

Edgeboard Connectors Overview

The EDAC Inc. 305-084-555-207 is a standard card edge connector from the 305 series, designed for dual-edge PCB applications. It features 84 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector supports a nominal printed circuit board thickness of 1.57 mm (0.062 inches). Electrical specifications include a current rating of 5 amps and a maximum contact resistance of 10 milliohms. The unit utilizes gold plating on the mating area and tin plating with nickel underplating on the tails.

Edgeboard Connectors Feature Summary

• Dual-row configuration designed for female connector applications on dual-edge PCBs
• Low profile insulator body constructed from thermoplastic material
• Gold plating on mating surfaces ensures reliable electrical connectivity
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment utilizing dual-edge card architectures
• Test and measurement instrumentation boards
• Computing hardware modules needing robust panel-mounted connections

Edgeboard Connectors Procurement Notes

Verify that the target application specifically requires a dual-edge card interface, as this component is not compatible with single-edge designs. Confirm the PCB thickness matches the specified 1.57 mm nominal requirement to ensure proper mechanical engagement. Check regional availability restrictions, as distribution channels may limit shipment in certain locations. Ensure the mounting style aligns with the panel design constraints before finalizing the order.

Edgeboard Connectors Selection Notes

Select this model when a high-position count connector is necessary for dual-edge PCBs. The 3.96 mm pitch offers a balance between density and ease of manufacturing compared to finer pitches. Consider the 5 amp current rating against the total load requirements of the circuit. The vertical panel mount style dictates the physical integration method within the enclosure structure.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series, which provides various mounting options and position counts for card edge applications. The series is characterized by its standardized dimensions and reliable performance in industrial environments. Similar models in the series vary primarily by position count and specific mounting configurations while maintaining consistent electrical characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 305-048-556-508 for lower position counts or 305-084-555-207 variants with different plating options. Verify that any replacement maintains the 3.96 mm pitch and 84-position count to ensure compatibility with existing PCB footprints.
