NJW Waterproof Cap
Brand :
MISUMI
Caution
Product Description
A waterproof cap for the NJW series that can be used for outdoor installation equipment such as surveillance cameras, construction equipment, and outdoor measuring instruments. It prevents dust and contaminant from entering the mating part when the connector is not connected, and maintains waterproof performance.
● Prevents intrusion of dust and foreign matter to the fitting part when connectors are not connected.
● It prevents accidents caused by touching live parts when not connected.
● 3 models are available: for straight, for relay, and for panel mounting.
·Other series connectors cannot be used.

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.
