JIS Standard Medium-sized Connector (NJC)

Features

● It has acquired the PSE mark (Electrical Appliance and Material Safety Act Compliant) and can be used widely from power supply to signal transmission.
● It is a JIS C 5432 compliant product and can be coupled with other companies' products that conform to the same standard.
● There are 3 types of connectors: Straight, relay, and panel mount connectors.
● Because all these connectors are connected by soldering, no dedicated tool is required for wiring.
