(Note 1) There are several types of clamp sizes depending on the finished external diameter of the wire used. Check the appropriate size in the clamp size table.
(Note 2) Since the weight differs depending on the clamp size, the weight table shows ranges.
Waterproof Medium Type Connectors (NJW)
Features
● NJW series connectors are round metal connectors, designed to enhance water-proofing functionality when mated. (IPX7 equivalent)● Light weight and superior strength enhanced by zinc die cast material (aluminum die cast for the shell size 28 connectors).
● Some of the products in the NJW series are PSE certified under the Electrical Appliance and Material Safety Law, and therefore can be used safely as a power supply.
● There are 3 types of connectors: Straight, relay, and panel mount connectors.
● Because these connectors are connected by soldering, no dedicated tool is required for wiring.
