The JAE MX31 Series connector datasheet provides specifications such as contact count, resistance, voltage rating, temperature range, current rating and…
The MX31 Series is a high‑density, compact connector designed for automotive use. It offers a 2.2 mm signal‑terminal pitch and a 3.2 mm power‑terminal pitch in a four‑row layout, with options for 70, 98, 104 or 135 contacts. The hybrid design supports both signal and power terminals, and the connector meets RoHS and aerospace‑grade requirements.
Materials include PBT housing, brass contacts with Sn or Au plating, and SPS resin for Pb‑free mounting. Detailed part numbers for male and female connectors, socket contacts, and crimping tools are listed, along with recommended wire sizes and board thicknesses.
