NC Relays

NC Relays Cautions for Use

  • 1.Because the NC relay is polarized, the positive "+" and negative "–" connections to the coil should be done as indicated on the wiring diagram. If connected incorrectly, it may malfunction or fail to operate.
  • 2.While NC relays can be used with any transmission-wave current to their operation, due to slight weakening of the force of magnetic attraction, decreased resistance to vibration and shock should be taken into account.
  • 3.When designing top and bottom view schematic diagrams, note that:
  • 1. "Top view" wiring diagram is indicated for the flat series because terminals can be seen from above.
  • 2."Bottom view" schematic diagram is indicated for the vertical series because terminals cannot be seen from above.

(Same direction)
  • 4.Cautions for close proximity mounting
    When using slim series in close proximity, mount all relays facing the same direction. Different mounting directions may cause change in the relay characteristics because NC relays are polarized.
