Brand :

MISUMI

Caution

Product Description

[Features]This is a single-action lock type straight plug manufactured by Nanaboshi Electric Mfg. A single-action NR connector developed from NJC series. Easy to attach/remove, a secure single-action lock type. Smooth mating with a 5-key guide. Made of die-cast, it is robust and lightweight.

● Easy to detach/attach, firm one-touch lock system.
● 5 key model guides for smooth mating.
● Robust and lightweight thanks to die-casting.

· Mating counterparts are relays or panel mount receptacles.
· Connecting is only possible with fellow NR connectors.
(Not possible to connect with NJC)
· Does not support key position changes.

One-Touch Medium Type Metal (NR)

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.
