1053965

Overview

The Phoenix Contact 1053965 is a PCB terminal block with a 2.5 mm pitch and four contacts. It features a push-in spring connection mechanism for rapid wiring without tools. The nominal current rating is 6 A, and the nominal voltage is 160 V. Rated voltage (III/3) is 100 V with a rated surge voltage of 2.5 kV. Contact resistance is 2.4 mΩ. The connector supports a nominal cross-section of 0.5 mm² and has a white housing with tin-plated contacts.

Feature Summary

• Push-in spring connection technology enables tool-free wire insertion and secure termination.
• Compact design with 2.5 mm pitch accommodates high-density PCB layouts.
• Tin-plated contact surfaces ensure reliable electrical conductivity and corrosion resistance.

Applications

• Industrial control panel wiring
• Signal distribution in automation systems
• Low-voltage power distribution on printed circuit boards

Procurement Notes

Verify the complete part number PTSM 0,5/ 4-P-2,5 WHBD:1-4CL to ensure correct labeling and configuration. Confirm that the 0.5 mm² wire capacity meets your specific cable gauge requirements. Check for RoHS compliance status if required by your project specifications. Ensure the 160 V rating aligns with your system's operational voltage limits.

Selection Notes

Select this component when a compact, tool-free connection method is required for small gauge wires. The 2.5 mm pitch allows for dense pin arrangements compared to larger pitch alternatives. Consider the 6 A current rating for load capacity planning. The push-in mechanism simplifies assembly processes compared to screw-terminal variants.

Part Context

This component belongs to the PTSM series of PCB terminal blocks from Phoenix Contact. The series is characterized by its space-saving design and push-in connection technology. The PTSM line offers various pole counts and pitch options to suit different density requirements in electronic assemblies.

Replacement Considerations

Direct substitutes must match the 2.5 mm pitch, 4-pole configuration, and push-in connection type. Verify identical current and voltage ratings to maintain safety margins. Alternative Phoenix Contact models with similar specifications may be considered if mechanical footprint compatibility is confirmed.
