Why Are Heavy-duty Connectors With Solder Pads Being Phased Out?

Another change in wire harness manufacturing is a move away from solder and tin-based components, such as the heavy duty waterproof electrical connectors with solder pads. As regulatory agencies in the United States and many other countries have imposed stricter restrictions on lead-containing materials, heavy duty 2 pin connector wire harness manufacturers have followed suit, phasing out the use of tin-plated terminals that require soldering and heavy duty connector 16 pin wire harnesses with solder pads.

In many heavy duty connector 5 pin wire harness applications, components such as fully insulated quick-disconnect devices do not require soldered connections.

heavy duty connector 6 pin harnesses require maintaining conductor strength in signal applications.

For heavy duty electrical contacts wire harness manufacturers, a persistent challenge comes from industry pressure to reduce wiring size and weight. With the increasing use of data-driven applications and components in modern vehicles, people have corresponding expectations for the wires in the heavy duty industrial connector wiring harness. Communication lines can operate efficiently on wires as small as 22 or even 26 gauges. However, this poses problems for heavy vehicles due to vibration issues and the possibility of disconnection.
