355-078-556-268

Edgeboard Connectors Overview

The EDAC Inc. model 355-078-556-268 is a standard card edge connector featuring 78 positions arranged in a dual-row configuration. It utilizes a contact spacing of 0.156 inches (3.96 mm) and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The component employs gold-plated copper alloy contacts with a solder pin termination type for secure electrical connections. Designed for panel mounting in a vertical orientation, the housing is constructed from black thermoplastic polyester. This connector supports a maximum operating temperature of +105°C and a minimum of -40°C, ensuring reliable performance across various industrial environments.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for non-specified card types
• Gold-plated copper alloy terminals ensure corrosion resistance
• Vertical panel mount style with solder pin termination

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge interfaces
• Consumer electronics assemblies needing high-density signal routing

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 78-position dual-row configuration before ordering. Confirm that the target application supports the specified 3.96 mm pitch and 1.57 mm board thickness constraints. Ensure compatibility with the vertical panel mounting style and solder pin termination method. Check environmental ratings against operational temperature ranges to guarantee long-term reliability in the intended deployment scenario.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface is required within a compact vertical footprint. The dual-row arrangement maximizes connection density without increasing the lateral profile. Choose this model if gold plating is necessary for maintaining low contact resistance over time. Consider the thermoplastic polyester housing for applications demanding stable mechanical properties under moderate thermal stress.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 355 series, which focuses on standard card edge solutions. The series provides versatile options for connecting double-sided edge cards to host systems. The 355 series is characterized by its consistent 3.96 mm spacing and durable construction materials suitable for general-purpose electronic interconnects.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 355 series variants for alternative position counts or row configurations. Verify mechanical dimensions and electrical ratings against potential substitutes to ensure functional equivalence in the existing assembly design.
