Caution
Product Description
There are 3 types, one for straight plugs, one for panel-mount receptacles, and one for inline adapters, to prevent dust and contaminant from entering the mating part when the connector is not connected.

● Prevents intrusion of dust and foreign matter when not connected.
● Three models: for straight, for relay, and for panel mounting.

Features
● NRW series connectors are round connectors, designed to enhance water-proofing functionality when connected. (IP67 equivalent)● Superior weather and impact resistance due to the high-strength plastic material used.
● NRW series products are suitable for power supplies.
● 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.
