Product details

100-Position Mezzanine Plug at 0.80 mm Pitch

Its 0.031" (0.80 mm) pitch packs 100 circuits into a dual-row layout, making it a dense signal interconnect for parallel data buses or high-I/O module stacking.

Stack Height Versatility from One Plug

This single plug supports four mated stacking heights — 8 mm, 12 mm, 16 mm, and 20 mm — by pairing with the corresponding Free Height (FH) receptacle of the correct height.

Surface-Mount Termination and Board Guide

Termination is surface-mount — the plug reflows onto the PCB with the rest of the SMT line. The board guide is a molded alignment feature that engages with the receptacle's guide posts before the contacts touch, preventing stubbing on the fine 0.80 mm pitch. No through-hole anchors; the SMT pads alone carry the mechanical retention, so the mated stack relies on the guide system for shear resistance during handling or vibration.
