Phoenix Contact 1778858 4-Pin 2.5mm Pitch - Custom Wire Harness

  • Terminal Specification: Engineered with a genuine Phoenix Contact 1778858 (PTSM 0,5/ 4-P-2,5) pluggable female terminal block, configured for 4-pin mating and utilizing a compact 2.5mm (0.098") pitch.
  • Conductor Accommodation (AWG): Architecture strictly supports the integration of standard stranded copper conductors ranging from 24 AWG up to 20 AWG (0.5mm²), ensuring optimal mechanical retention in high-density applications.
  • Termination Methodology: Incorporates toolless push-in spring connection technology at the terminal interface, establishing a rapid, gas-tight, and vibration-resistant electrical junction without the need for manual screw torquing.
  • Electrical Tolerances: The PTSM series interface is precision-engineered to support a maximum nominal current of 6A and a rated voltage of 160V, optimized for robust low-voltage signal and power transfer.
  • Routing Architecture: Configured as a discrete wire harness designed for space-restricted, point-to-point bridging in compact industrial controllers, LED lighting arrays, and automated sensor modules.

What information do you need to provide a quote for a custom wire harness?

To provide an accurate quote and lead time, please provide:

  1. Technical Drawing or Diagram: Showing pinouts, lengths, and tolerances.
  2. Bill of Materials (BOM): Listing specific connectors (MPN) and wire gauges (AWG).
  3. Estimated Annual Usage (EAU): Helping us optimize pricing for your volume. Note: If you do not have a formal drawing, our engineering team can help create one based on your physical sample.
Can you suggest cost-saving alternatives for expensive connectors (e.g., TE, Molex, JST)?

Yes. We offer variety of alternative components.

We have extensive supply chain relationships in Taiwan and can suggest"Functionally Equivalent"alternatives that are fully compatible with major brands like TE, Molex, or JST but at a significantly lower cost. We will provide datasheets and samples of the alternative components for your approval before production.

How do you ensure quality control for custom cable assemblies?

Every single cable assembly undergoes rigorous testing before leaving our Taiwan facility. Our standard QC process includes:

  • 100% Continuity Testing: Ensuring no opens, shorts, or miswires.
  • Pull Force Testing: Verifying crimp strength.
  • Visual Inspection: Checking for cosmetic defects and label accuracy.
  • Hi-Pot Testing: Available upon request for high-voltage applications to ensure insulation integrity.
