Terminal block plug, 4-way, rising cage clamp
The 1986370-4 is a 4-position plug with female sockets from TE Connectivity AMP Connectors, terminated by a screw-driven rising cage clamp that accepts 14-30 AWG (0.05-2 mm²) wire.
Free-hanging, side-stackable design
The plug mates in-line with the header and accepts wire entry at 90°, with a side-stacking feature that allows multiple plugs to be ganged side-by-side without additional hardware. An M2 screw secures the rising cage clamp, and the green housing colour is consistent across the series for visual identification.
