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.
