  • Samples

Connectors for signal circuits or power supply circuits, applicable to the factory automation, heavy electric machinary, and other industrial equipment in general. In spite of the various kinds of housings available, their contacts are designed to be common. Thus the applicable tooling can be unified.






  • Double-spring construction

For superior contact reliability, the receptacle contact has a double-string construction consisting of a main spring and a contact pressure adjustment spring.

In addition, a spring stopper is incorporated in the connector to facilitate resistance to excessive pressure.

  • Housing lances

Lances are incorporated into the housing design to secure the contacts, therefore keeping contact insertion force low and avoiding contact deformation.

  • Secure locking method

When housings are mated, a clear locking sound can be heard to ensure secure engagement.

  • Recognition mark

Both contacts and application tools have identification marks to prevent incorrect combinations.
