1202137

Overview

Phoenix Contact part number 1202137 is a COMBIFIX plug-in connector designed for modular terminal block systems. It features a 4-position configuration with a 5.2 mm pitch, accommodating rigid conductors from 0.08 to 4 mm² and flexible conductors from 0.08 to 2.5 mm². The component supports a nominal current of 24 A at a rated voltage of 500 V, with an impulse withstand voltage of 6 kV. Constructed from gray PA insulation (RAL 7042), it meets IEC 61984 standards and offers Overvoltage Category III protection in Pollution Degree 3 environments.

Feature Summary

• Utilizes spring-cage connection technology for secure tool-free wiring without requiring separate ferrules.
• Features a standardized 5.2 mm pitch compatible with the Phoenix Contact COMBIFIX series.
• Includes mechanical locking mechanisms to ensure stable mating with corresponding socket components.

Applications

• Industrial control cabinet signal distribution
• Automation system interconnects
• Machine building electrical assemblies

Procurement Notes

Verify the specific suffix code against official catalogs to confirm exact pin count and color coding. Ensure compatibility with the intended COMBIFIX base terminal blocks regarding pitch and locking mechanism. Cross-reference technical data sheets for updated environmental ratings before final specification approval.

Selection Notes

Select this component based on the required conductor cross-section range and the need for reliable spring-cage connections. Consider the 5.2 mm pitch requirement for space-constrained layouts. Evaluate the 500 V rating against system voltage requirements and verify insulation material suitability for the operating temperature range.

Part Context

This component belongs to the Phoenix Contact COMBIFIX product family, which provides standardized plug-in solutions for industrial automation. These connectors facilitate rapid assembly and maintenance by allowing easy separation of signal lines from terminal blocks without disturbing the underlying wiring structure.

Replacement Considerations

Direct substitutes are limited within the same manufacturer's portfolio due to specific pitch and locking variations. Verify compatibility with existing base terminals before considering alternative models from other manufacturers, as interface dimensions often differ significantly across brands.
