1221490

Overview

The Phoenix Contact 1221490 is a COMBIFIX plug connector with 9 positions and a 5.2 mm pitch. It features a pull-back spring connection mechanism for wires with a rated cross-section of 2.5 mm². The component has a rated surge voltage of 6 kV, a nominal current of 24 A, and a rated voltage of 500 V. Constructed from PA insulation material in grey (RAL 7042), it meets IEC 61984 standards and offers UL 94 V-0 flame retardancy.

Feature Summary

• Utilizes a pull-back spring connection system for secure wire termination without tools.
• Designed as a switchless capacity connector compliant with IEC 61984 for safe mating under no-load conditions.
• Features high dielectric strength with a rated surge voltage of 6 kV and overvoltage category III classification.

Applications

• Industrial control cabinet wiring
• Signal distribution in automation systems
• Railway vehicle electrical installations

Procurement Notes

Verify the specific pin count matches the design requirement of nine positions. Confirm that the 5.2 mm pitch aligns with the mating socket or PCB footprint. Ensure the 2.5 mm² wire gauge capability suits the circuit's current carrying needs. Check that the 500 V rating is sufficient for the operating environment. Validate compliance with local safety regulations regarding overvoltage category III.

Selection Notes

Select this model when a compact, tool-free connection solution is required for multiple signal lines. The 5.2 mm pitch allows for higher voltage isolation compared to finer pitches. Consider the 24 A current capacity if powering low-voltage loads directly through the terminal. The spring connection simplifies assembly and maintenance compared to screw terminals.

Part Context

This component belongs to the Phoenix Contact COMBIFIX series, which provides modular interconnection solutions for industrial applications. The series is characterized by its standardized dimensions and compatibility across various pin counts. These connectors are widely used in environments requiring reliable, vibration-resistant connections.

Replacement Considerations

Direct substitutes must maintain the 5.2 mm pitch, 9-position configuration, and spring connection type. Verify that any alternative part shares the same 6 kV surge voltage rating and 500 V nominal voltage. Ensure mechanical compatibility with existing mounting rails or panels.

FAQ

What is the maximum wire cross-section supported by this connector?

The connector supports a rated wire cross-section of 2.5 mm², with a permissible range up to 4 mm² for rigid wires.

Is this connector suitable for use under load?

No, it is a switchless capacity connector designed for connection or disconnection only under no-load or no-voltage conditions according to IEC 61984.
