NRW Series

Made of resin and lightweight. One-touch locking system makes it ideal for portable devices.
Has a proven track record in outdoor measuring instruments, semiconductor manufacturing equipment, and inspection equipment.


RoHS RoHS compliant
Waterproof Waterproof connector [Waterproof function equivalent to IP-67 when connected] (IP-68 class also available upon request)
Locking Method One-touch lock system
Mechanism and Material Features
  • The shell is made of high-strength plastic with excellent weather resistance.
  • Lightweight and durable
  • Using an L-shaped seat allows installation in narrow spaces
About Standards
  • UL/CSA certified products available (UL: UL1977 CSA: C22.2 No.182.3)
  • Products that comply with European safety standards (EN61984 compliant, TÜV certified)
Wiring Method Solder and crimp types available (both interchangeable)


  • Insulation resistance: When measured between the nearest conductors at the specified voltage, it is 1,000 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 5 mΩ or less.
  • Vibration resistance : When a vibration test was performed, there was no functional problem and the contact resistance was 5 mΩ or less.
  • Impact: When an impact test is performed, there is no functional problem and the contact resistance is 5 mΩ or less.
  • Moisture resistance: After a humidity test, there is no functional impairment and the insulation resistance is 10 MΩ or more.
  • Temperature cycle: After the temperature cycle test, there is no functional problem and the insulation resistance is 1,000 MΩ or more.
  • Salt spray: After conducting the salt spray test, there is no functional problem and the contact resistance is 5 mΩ or less.
  • Waterproof: After being left under 40kPa water pressure for 24 hours under normal use conditions, there is no sign of water ingress.


Align the plug and receptacle guides and push straight in.
(Because it is a five-key system, you can align the guides by placing the plug on the receptacle and rotating the plug.)
Note) When inserting, do not twist the coupling nut.


Rotate the coupling nut 45° to the left in the direction of the arrow and pull it out.
Note: Do not twist the end bell when removing it.
