Board-to-Cable connection, high density connector for automotive
Outline
 High density and non-water proof type of MX31 series is developed to meet the demands for compact and lighter connectors with multi pin counts, due to increase of computerized control in automotives. Pitch of signal terminal is 2.2mm, and the pitch of power terminal is 3.2mm. Compact and 4rows type and the variation of the number of terminal is from 70pos. to 135pos. (pin header) this connector meets with automotive specs. And the application is for automotive EUC (engine, transmission, etc.)
  2.2mm terminal pitch for signal, 3.2mm terminal pitch for power are 4rows type compact high density connector.
  Hybrid connector with terminals for both signal and power.
  Connector insertion force is under 70N and it enables easy mating work.
  Socket terminal is a newly developed terminal with countermeasure for fretting corrosion by slight conflicts.
  Lead-free mounting compatible by using heat resistant resin (SPS material)
  Plating type of terminal: Tin plating or Gold plating.
