Current -time value of movement of free electrons. One ampere equals one coulomb per second. Conventional reference is opposite to direction of actual electron movement. See supply current . Current Sinking -an output type such that when it is On, current flow is from the load into the device's output, then to ground.
Output is Normally High.
The load is connected between the positive lead of the supply and the output lead of the sensor. Current Sourcing -an output type such that when it is On, current flow is from the device into the load. Output is Normally Low. The load is connected between the output lead and the negative ground lead of the supply. Dead Break -Imperfect snap action in which the normally closed circuit of the switch opens before the plunger reaches the operating point, or the normally open circuit opens before the plunger reaches the release point.
