Product Introduction

This lead uses a yellow-green UL1015 16AWG tinned-copper wire, with a ring crimp terminal at one end and a B1811T2P-2E PCB board terminal at the other. Black heat-shrink tubing covers both junctions for insulation and strain relief. It is built as a fixed grounding connection inside electronic equipment, with the terminal sizes and lead length set per the approved drawing.

Product Features

  • Ring terminal 7543, OD 7.5mm, at one end
  • B1811T2P-2E board terminal, 2.4mm PCB hole, at the other
  • Yellow-green UL1015 16AWG tinned-copper wire
  • Black heat-shrink tubing at both junctions
  • Fixed lead length of about 112mm

Technical Specifications

  • Pin count: single-circuit grounding lead
  • Wire: UL1015 16AWG tinned-copper hookup wire
  • Terminals: ring crimp terminal and PCB board terminal
  • Protection: black heat-shrink tubing
  • Testing: 100% continuity test on finished leads

Quality Assurance

We produce to customer drawings and samples, from prototype to volume production. All leads are continuity tested before delivery, and crimp quality is verified by pull-test sampling. Wire color and terminal options can be adjusted for different equipment designs.
