Contact system and wire range
The 140787-2 is a non-insulated circular ring terminal from TE Connectivity's AMP line, accepting 16-22 AWG wire with a crimp termination. The tin-plated brass contact carries a 0.025" (0.64mm) material thickness, and the insulation diameter range is 0.059" to 0.118" (1.50mm to 3.00mm).
Sibling ring terminals in the AMP non-insulated line
Within the TE non-insulated ring terminal family, the 140787-2 (16-22 AWG) sits between the 140546 (14-18 AWG) and the 170225-1 (18-22 AWG) — the crimp termination and tin-plated brass construction are shared across the series, so select the wire gauge match for the harness. The 160252-2, another sibling, covers 15-20 AWG with a shorter 0.488" overall length versus the 140787-2's 0.976".
