  • Insulation resistance: When measured between the nearest conductors at the specified voltage, it is 5,000 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: After being left under a water pressure of 40kPa for 24 hours under normal use conditions, there is no sign of water entering the device.
