2-5-7 Parallel
Connection
(Wiring Example of the Control Category 4)
This is the configuration for connecting multiple sets of emitter and receiver facing each other
in parallel. It is used when there are two dangerous parts and each dangerous part can be
entered from only one direction. By connecting the interference prevention line, up to three
sets of the sensors can be connected. For the control output (OSSD 1, OSSD 2), only the
output of the sensor of which light is blocked turns OFF.
For parallel connection, connect the one receiver to the other connection using the interfer-
ence prevention line as shown in the figure on the next page. Wrong connection could gen-
erate the non-sensing area, resulting in serious injury or death.
