305-030-556-208

Edgeboard Connectors Overview

The EDAC 305-030-556-208 is a standard card edge connector from the 305 series, designed for panel-mounted applications. It features a dual-row configuration with 30 positions and a contact spacing of 3.96 mm (0.156 inches). The connector utilizes gold-plated copper alloy contacts with a solder lug termination type. It is engineered to accept printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The unit includes #4-40 unified threaded inserts for secure mounting and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for enhanced signal integrity
• Features a low-profile insulator body constructed from thermoplastic material
• Provides a continuous current rating of 5 A with high dielectric strength

Edgeboard Connectors Applications

• Panel-mounted electronic interconnections
• Dual-edge card edge board connections
• Industrial control system hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct insulation color and terminal configuration. Confirm that the required polarizing keys are ordered separately if needed for the application. Check regional availability as distribution may be restricted in certain areas. Ensure compatibility with the target PCB thickness of 1.57 mm before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel mounting. The 30-position count suits moderate-density interconnect needs. Verify that the 5 A current rating meets the electrical load requirements. Ensure the design accommodates the #4-40 threaded insert mounting style rather than surface-mount or through-hole pin configurations.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by its robust construction and ability to handle polarizing keys. Similar models in the series vary by position count, such as the 305-018 or 305-050 variants, but share the same fundamental 3.96 mm pitch and panel-mount architecture.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include parts with identical row counts and pitch but different position numbers, such as 305-018-556-208 or 305-050-556-208. Cross-brand replacements require matching the 3.96 mm pitch, dual-row layout, and 1.57 mm board thickness tolerance.
