Operating temperature:
-40 Deg. C to +85 Deg. C
Rated current:
2.2A for signal, 5.7A for power
Features
MX31 Series
Board to Cable Connection
High Density Connector for Automotive
General Specifications
2.2mm terminal pitch for signal, 3.2mm terminal for power are 4 row 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.
Pb-free mounting compatible by using heat resistant resin (SPS material)
Plating type of terminal: Sn plating or Au plating
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 4row 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)
Insulation resistance: 100M ohm max.
Mating cycle: 50cycles
Applicable wire:
