Features

● The NR series features compact multi-core metal connectors with zinc die cast materials used for the shell.
● Secure connectors used for a wide variety of applications from power supply to signals.
● There are 3 types of connectors: Straight connectors for cable mounting, relay connectors, and panel mount connectors for panel mounting.
● Because all these connectors are connected by soldering, no dedicated tool is required for wiring.
