Parallel Connection - Panasonic SF4B-F23 V2 Instruction Manual

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 en-
tered from only one direction. By connecting the interference prevention line, up to three sets of
the devices can be connected. For the control output (OSSD 1 / 2), only the set of which light is
blocked turns OFF.

For parallel connection, connect the one receiver to the other connection using the
interference prevention line as shown in the figure on the next page. Wrong con-
nection could generate the non-sensing area, resulting in death or serious injury.
