NWPC Series

A waterproof connector based on the NCS series. The shell is made of brass with chrome plating. It is robust and resistant to salt damage, making it suitable for a wide range of applications, including civil engineering and construction machinery, emergency power supply equipment, and ships.


RoHS RoHS compliant
Waterproof Waterproof connector [Waterproof function equivalent to IP-X6 when connected]
Locking Method Screw locking method
Mechanism and material features
  • The shell is made of brass with chrome plating, providing excellent corrosion resistance.
  • Cable clamps are provided at the cable outlet to hold the cable securely (except for size 14)
About standards
  • certified products available (CSA: C22.2 No.182.3)
Wiring Method Soldering
Operating Temperature Limit -40℃~+85℃
Notes Contacts with a rated current of 80A or more are designed to be removable from the insulator.
When soldering, remove the contacts with a contact wrench.


  • Insulation resistance: When measured between the nearest conductors at the specified voltage, it is 2,000 MΩ or more.
  • Withstand voltage: No short circuit or other abnormalities occur even when the specified voltage is applied between the closest conductors for one minute.
  • Contact resistance: When a pair of contacts is joined to the correct length, the conductor resistance is 3 mΩ or less.
  • Waterproof: Under normal conditions of use, there is no sign of water leakage after being left submerged in 5cm of water for 24 hours.
