1581657

Overview

The Phoenix Contact model 1581657 is a COMBICON series PCB connector designed for reliable signal and power transmission in industrial automation. It features a 2-position configuration with a 5.0 mm pitch, utilizing push-in spring connection technology for tool-free assembly. The component supports a rated voltage of 320 V and a rated current of 17 A. Constructed with UL 94 V-0 flame-retardant housing, it ensures safety in demanding environments. This connector is part of the broader COMBICON family, offering compact solutions for control cabinet wiring.

Feature Summary

• Push-in spring connection technology enables rapid, tool-free wire termination without requiring special instruments.
• Compact design with 5.0 mm pitch allows for high-density mounting on printed circuit boards.
• Flame-retardant housing material meets UL 94 V-0 standards for enhanced fire safety.

Applications

• Industrial automation control systems
• Signal and power distribution in control cabinets
• Machine building interconnections

Procurement Notes

Verify the specific pin count and pitch against project schematics to ensure compatibility with existing PCB layouts. Confirm that the push-in connection method aligns with the facility's assembly protocols and wire preparation requirements. Cross-reference the rated electrical parameters with the actual load conditions to prevent operational exceedances.

Selection Notes

Select this component when tool-free assembly speed is prioritized over traditional screw connections. Ensure the application environment does not require higher current ratings than 17 A or voltages exceeding 320 V. Consider the 5.0 mm pitch constraint when designing board space allocation relative to other COMBICON variants.

Part Context

This item belongs to the Phoenix Contact COMBICON series, a widely used line of PCB connectors known for reliability in industrial settings. The series offers various positions and connection technologies, including screw and spring types, catering to diverse data, signal, and power transmission needs across automation sectors.

Replacement Considerations

Direct substitutes within the same series must match the 2-position count, 5.0 mm pitch, and push-in connection mechanism. Verify that alternative part numbers maintain identical electrical ratings and mechanical dimensions to ensure seamless integration without redesigning the host equipment.
