2277187

Overview

The Phoenix Contact 2277187 is a PCB terminal block designed for secure electrical connections in industrial control environments. It features a nominal current rating of 12 A and supports a nominal voltage of 630 V. The device accommodates conductor cross-sections ranging from 0.5 mm² to 2.5 mm², with support for solid and stranded wires including those with ferrules. It utilizes a spring-cage connection mechanism for tool-free or simple tool-assisted wiring. The unit has a pitch of 5.08 mm and is available in a single-pole configuration.

Feature Summary

• Spring-cage connection technology ensures reliable contact without the need for soldering.
• Compact design allows for high density mounting on printed circuit boards.
• Supports both solid and stranded conductors with ferrule sleeves for versatile wiring options.

Applications

• Industrial automation control panels
• Signal distribution in machinery
• Power supply connections for low-voltage systems

Procurement Notes

Verify that the specific ordering number matches the required pole count and color coding. Confirm that the housing material meets the flame resistance class requirements for your application environment. Ensure compatibility with existing PCB footprint dimensions before finalizing procurement orders.

Selection Notes

Choose this component when space constraints require a compact terminal solution with high vibration resistance. The spring-cage mechanism offers faster assembly compared to screw terminals. Verify that the operating temperature range aligns with the environmental conditions of the installation site.

Part Context

This component belongs to the Phoenix Contact universal series of PCB terminal blocks. These devices are engineered for robust performance in demanding industrial settings. The series provides standardized interfaces for connecting external wiring to internal circuitry efficiently.

Replacement Considerations

Check for direct substitutes within the same Phoenix Contact product family that share identical mechanical dimensions and electrical ratings. Ensure any replacement maintains the same pitch and connection type to fit existing PCB layouts without modification.
