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.
