Convergent beam scanning is used to detect the presence or absence of small objects while ignoring nearby background surfaces. Convertible Output -output that can be wired either as Normally Open or Normally Closed, but not at the same time. Corrective Factor -the mathematical factor that, when multiplied by the sensing distance of a given sensor, will adjust sensing distance for the different metals being used as targets. 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.
