Panasonic's new concept of connecting 6 sets of sensor heads to 1 controller in series offers you maximum flexibility to solve your safety application. Just configure exactly the number of sensor heads and controllers required to protect the area in question, e.g. small openings or irregularly shaped spaces impractical for safety light curtains.
A beam interruption indicator is incorporated in both the emitter and receiver, which not only eases confirming operation but also facilitates aligning the beam axis.
The high-functional controller ST4-C12EX immediately diagnoses misaligned or abnormal sensor heads. Its digital display allows you to identify errors at a glance, and it supports both PNP and NPN polarities, easing stock management.
