Waterproof connector

The relatively compact one-touch detachable type or bolt connection type electric couplers are called "connectors".
With lightweight, easily detachable, and perfectly waterproof characteristics, these are widely used as couplers between railway cars, in equipment leads, or in ordinary industrial equipment, etc.

High-voltage connectors (YH Series)

YH3, YH400 Series

Product characteristics
  • Perfectly waterproof single-wire high-voltage connector. Used mainly for the main circuits and bus circuits in railway cars, for grounding circuits spanning between railway cars, or for motor wiring, etc.
  • YH3 is a bolt tightening-type connector, optimal for locations with few detachments and attachments. YH400 Series is a ball lock type one-touch connector, optimal for locations where simple connection is wanted.
