1239741

Overview

The Phoenix Contact 1239741 is a PCB terminal block designed for secure electrical connections in industrial automation environments. It features a nominal current rating of 8 A and supports a rated voltage of 630 V. The device accommodates conductors with cross-sections ranging from 0.5 mm² to 2.5 mm², including flexible wires with ferrules. It utilizes a push-in spring connection mechanism for tool-free installation, ensuring rapid assembly without the need for screwdrivers. The unit is available in a single-pole configuration with a pitch of 5.08 mm.

Feature Summary

• Push-in spring connection technology enables tool-free wiring and quick installation
• Compact design suitable for high-density mounting on printed circuit boards
• Robust construction ensures reliable performance under industrial operating conditions

Applications

• Industrial control cabinet wiring
• Automation system signal distribution
• Sensor and actuator interface connections

Procurement Notes

Verify that the specific order code matches the required pole count and color coding. Confirm compatibility with existing PCB layouts regarding pitch dimensions. Ensure that the conductor specifications align with the terminal's acceptance range for ferrules or solid wires. Check for any updated safety certifications relevant to your region before finalizing procurement.

Selection Notes

Select this component when space constraints require a compact terminal solution with fast installation capabilities. Consider the push-in mechanism if frequent rewiring or maintenance is anticipated. Evaluate the voltage and current ratings against the specific circuit requirements to ensure adequate safety margins. Verify that the insulation material meets the necessary flame retardancy standards for the intended application environment.

Part Context

This terminal block belongs to Phoenix Contact's standard series of PCB connectors, widely used in modular control systems. It complements other components in the same family, allowing for mixed configurations within a single control panel. The design philosophy emphasizes ease of use and reliability in harsh industrial settings, supporting efficient production and maintenance workflows.

Replacement Considerations

Direct substitutes must match the 5.08 mm pitch, 8 A current rating, and push-in connection type. Verify physical dimensions to ensure fit within the designated PCB footprint. Cross-reference part numbers from alternative manufacturers only if they explicitly state compatibility with these technical specifications.
