357-018-556-212

Edgeboard Connectors Overview

The EDAC Inc. 357-018-556-212 is a standard card edge connector from the 357 series, designed for vertical panel mounting applications. It features an 18-position dual-edge female configuration with a 3.96 mm (0.156 inch) contact pitch. The connector utilizes gold-plated copper alloy contacts and a black thermoplastic polyester housing. It accommodates board thicknesses ranging from 1.37 mm to 1.78 mm (0.054 to 0.070 inches). The unit operates within a temperature range of -40°C to +105°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design for secure board insertion
• Vertical panel mount orientation with flange support
• Gold-plated contacts on copper alloy substrate
• Thermoplastic polyester insulation for durability

Edgeboard Connectors Applications

• Medical interconnect solutions
• Agricultural technology equipment
• Industrial control systems
• Communication infrastructure

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 307/357 Ordering Guide to ensure correct flange style and termination type. Confirm that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range. Check regional distribution availability as stock levels may vary by location. Ensure compliance with required environmental certifications such as RoHS3 for the intended application market.

Edgeboard Connectors Selection Notes

Select this component when a vertical, dual-edge connection is required for boards between 1.37 mm and 1.78 mm thick. The 3.96 mm pitch suits general-purpose signal routing rather than high-density micro-electronics. Consider the 357 series' robust mechanical design for environments requiring reliable physical retention. Verify that the operating temperature range meets the system's thermal requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 357 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing a consistent 3.96 mm pitch and durable construction. The 357 series is widely utilized in industrial and medical sectors where reliable, long-term connectivity is essential. This specific model provides a balanced solution for moderate pin counts in vertical configurations.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 357 series cross-reference guide for direct substitutes with different position counts or flange variations. Generic card edge connectors may match dimensions but often lack the specific gold plating thickness or material specifications. Verify that any alternative maintains the same 3.96 mm pitch and compatible board thickness tolerance.
