All the systems I've seen in Japan use NPN sensors and the DC24V is left floating. Machine safety doesn't seem to be such a high priority here as it is in the west. No lockable isolators and e-stops connected directly to PLC inputs. Maybe the operators are a bit more careful here, or perhaps they just keep quiet when they lose a finger!
