1944631

Overview

Phoenix Contact part number 1944631 is a pluggable terminal block from the MSTBVA 2.5/6-G-RN series, designed for PCB socket applications. It features a single row with six positions and a 5 mm pitch. The component utilizes spring-cage connection technology for secure wiring. Rated for 400 V nominal voltage, it supports wire cross-sections ranging from 0.08 mm² to 2.5 mm². The housing is green, and the unit is intended for through-hole mounting on printed circuit boards.

Feature Summary

• Utilizes spring-cage connection method for reliable wire termination without tools.
• Designed as a PCB socket plug compatible with COMBI connector systems.
• Features a shrouded header design to ensure proper alignment and safety.

Applications

• Industrial control panel wiring
• Signal distribution in automation systems
• PCB-to-wire interconnection in electrical enclosures

Procurement Notes

Verify the specific ordering suffix matches the required insulation color and pin configuration. Confirm that the spring-cage mechanism aligns with the target wire gauge range. Ensure compatibility with mating plugs from the same COMBI series family. Check technical datasheets for peak current ratings under specific ambient temperature conditions before finalizing procurement.

Selection Notes

Select this model when a six-position, 5 mm pitch terminal block is required for PCB mounting. The spring-cage connection offers vibration resistance suitable for industrial environments. Consider the 400 V rating and 2.5 mm² maximum cross-section against load requirements. Verify that the green housing color meets visual coding standards for the installation site.

Part Context

This component belongs to the Phoenix Contact COMBICON M series, specifically the MSTBVA variant. These connectors are standardized according to IEC 61984 for use in low-voltage power distribution and signal transmission. The product line emphasizes modular expansion capabilities and robust mechanical stability for permanent PCB installations.

Replacement Considerations

Direct substitutes must maintain the 6-position count, 5 mm pitch, and spring-cage interface. Verify that alternative models support the same 400 V rating and 2.5 mm² wire capacity. Ensure physical dimensions allow for identical PCB footprint replacement without board modification.

FAQ
