1543932

Overview

Phoenix Contact part number 1543932, also identified as M23-12S2N1280DU, is an M23 series cable connector designed for signal applications. This straight, shielded plug features a screw locking mechanism and twelve positions with female hole contacts intended for soldering. The contacts are gold-plated over nickel on brass substrates. It supports a maximum current rating of 8 A and operates within a temperature range of -25°C to 80°C. The component meets RoHS standards and provides electromagnetic interference protection through its shielding design.

Feature Summary

• Straight design with screw locking mechanism for secure attachment
• Shielded construction to protect against electromagnetic interference
• Gold-plated contacts on brass substrate for reliable signal transmission
• Female hole contacts configured for soldering electrical mounting

Applications

• Industrial signal transmission systems
• M23 PRO series equipment connections
• Electromagnetic sensitive circuit interfaces

Procurement Notes

Verify the specific ordering suffix matches the required contact configuration and cable diameter specifications. Confirm that the soldering termination type aligns with your assembly process capabilities. Ensure the M23 interface compatibility with mating connectors in your system design before procurement.

Selection Notes

Select this component when a shielded M23 plug with twelve positions is required for signal integrity. The screw locking mechanism offers robust mechanical stability compared to push-pull variants. Consider the soldering requirement for installation and verify the 8 A current rating suffices for the intended load conditions.

Part Context

This connector belongs to the Phoenix Contact M23 PRO series, which focuses on high-density signal transmission in industrial environments. The M23 standard provides a compact form factor suitable for space-constrained applications requiring reliable connectivity. The series emphasizes durability and consistent performance under varying operational temperatures.

Replacement Considerations

Direct substitutes must match the M23 interface, 12-position count, and soldering termination. Verify shielding requirements and screw locking mechanisms are identical to maintain system integrity and electromagnetic compatibility.
