WPJ CONNECTOR
5.0mm pitch/Disconnectable Crimp style connectors
• Waterproof performance [Grade 7 ingress
protection of JIS C 0920 (IPX7 of IEC 60529 ) ]
• Control key system
• Contacting part of contact is hardly deformed
• Inner locking system
• Compact design
Compact, Water Resist and Durable. This
connector for electrical connection can be
used on both waterproof and non-
waterproof conditions, depending on the
usage. Just by placing a rubber part will
change it into a water resistant connector.
Both conditions are using the same
header.
Note: 1. The above figure is the figure viewed from the connector mounting side.
2. Tolerances are non-cumulative:
±
0.05 mm for all centers.
3. The dimensions above should serve as a guideline. Contact JST for details.
