Molex PicoBlade 1.25mm to JST XH 2.5mm Pitch 4-Pin - Electrical Wire Harness Assembly

  • Inter-Brand Connectivity: Bridges Molex PicoBlade (51021 series) and JST XH (XHP series) 4-pin connectors for seamless signal or power integration.
  • Pitch Conversion: Facilitates transition between high-density 1.25 mm micro-pitch and standard 2.5 mm board-to-wire interfaces.
  • Industrial Grade Materials: Constructed using UL1007 or UL1061 certified discrete wire with tin-plated copper conductors for superior corrosion resistance.
  • Optimized for Precision: Engineered for low-voltage signal transmission in robotics, medical instrumentation, and industrial automation control systems.

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.
