Low (0 to 2.5V): Emission halt
High (6 to 30V, or open): Emission
Notes: 1) The emitter of the thru-beam type sensor does not incorporate the
output and the control input. When the mating cable is connected
to the pigtailed type, the color of the control input wire is white.
2) Test input (emission halt input) is incorporated only on the
emitter of the thru-beam sensor. When the mating cable
is connected to the pigtailed type, its color is white.
