What this plug mates with and where it fits
The 1986716-8 is a Plug for Unshrouded Header, meaning it mates with standard unshrouded pin headers of matching pitch and position count. The 0.138" (3.50mm) pitch and 8 positions line up with common TE and industry-standard headers for signal-level wiring. Rated 2 A at 150 V, this plug is suited for control signals, sensor inputs, and low-power I/O inside an enclosure. The 16-20 AWG wire range and screwless push-in spring termination accept solid or ferruled stranded wire without a tool. The green housing and 90° wire entry make it easy to route wires along the board edge, keeping the harness tidy in a panel or junction box.
Wiring and assembly details
Termination is screwless – the leg spring pushes the wire into the contact when you press the push button. Strip length is 8.5-10 mm; no crimp ferrule is required, though a ferrule helps stranded wire stay compact. Side stacking lets you gang multiple plugs side-by-side to build wider multi-circuit blocks. The push button actuation on each position releases the wire individually, which helps during rework or last-minute changes. Contact mating finish is tin, which is fine for the rated 2 A and moderate mating cycles typical of terminal block applications. The steel, stainless contact material provides spring retention without plating wear concerns.
