[Connectable up to 3 sets (however, 192 beam channels max.)]

This is the configuration when multiple sets of emitters and receivers facing each other are

connected in series. It is used when the dangerous area can be entered from two or more

directions. The control output (OSSD 1, OSSD 2) turns OFF if light of any set is blocked.

 For series connection, connect emitter and emitter, receiver and receiver,

 When multiple sets of sensors are connected in series, the response time is

+9V to Vs: Emission (at 2mA or less sink current) (Note)

Open or 0 to +1.5V: Emission halt

Note: Vs is the same voltage as the voltage of the power supply to be used.

Use a safety relay unit or an equivalent control circuit in safety for FSD.

If the sufficient distance is not maintained, the machine will not stop before its

dangerous parts are reached, which can result in serious injury or death.
