  • Limitswitch technical guide

    Positive break contact operation (IEC 947-5-1, chapter 3) For contacts used in safety applications, limit switches, emergency stop devices, assurance that opening has occurred is essential (see IEC 204, EN60204). After each attempt, contact opening is checked by an impulse voltage test (2500 V).

  • Electrical Ratings - NKK Switches

    100% of the load is composed of resistive devices. The power factor is high (PF = 1) and contact erosion is low. Consequently, the switch’s electrical life can be antici-pated with some certainty. Lamp Load When a switch closes on a resistive lamp load, the switch sees a short circuit because the cold resistance of the lamp filament is near zero.

    I/O Wiring and Specifications In the previous section on Sourcing and Sinking concepts, we explained that DC I/O circuits sometimes will only allow current to flow one way. This is also true for many of the field devices which have solid-state (transistor) interfaces. In other words, field devices can also be sourcing or sinking.
