305-060-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-060-556-258 is a standard card edge connector designed for dual-edge board applications. It features 60 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a thickness of 10.0 µin (0.25 µm) and employs a half-beam contact type for secure mating. It accommodates PCB thicknesses ranging from 1.37 mm to 1.78 mm (0.054" to 0.070"). The unit is rated for 5 A current, operates within a temperature range of -40°C to +105°C, and uses thermoplastic insulation.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with half-beam contact design for reliable signal transmission
• Gold-plated copper alloy terminals ensure corrosion resistance and low contact resistance
• Thermoplastic polyester housing provides structural integrity and thermal stability
• Panel mount installation style with vertical orientation for robust mechanical support

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Computer peripheral interface boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact plating thickness, flange characteristics, and termination style. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm RoHS3 compliance requirements if applicable to the assembly process. Cross-reference the 60-position count and 3.96 mm pitch with system design specifications to prevent mechanical mismatch during integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required for panel-mounted applications. The 5 A current rating and -40°C to +105°C operating range suit demanding industrial environments. Choose this model over single-edge variants if both sides of the circuit board require connection. Verify that the half-beam contact type aligns with the insertion force constraints of the host system.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options. The 305-060-556-258 specifically denotes a 60-position dual-edge variant. Similar parts in the series include the 305-050-556-201 and 305-080-555-568, which share the same pitch and general construction but differ in pin count and flange details.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series must match the 60-position count and 3.96 mm pitch. Parts like 305-060-556-201 may serve as alternatives if flange differences are acceptable. Verify that any replacement maintains the dual-edge female configuration and compatible PCB thickness range.
