Sensor identity and output logic
The Omron E3F2-DS10Z1-N-2M is a photoelectric switch in the E3F2 series, with an NPN output and a 2-meter cable. The "-N" suffix in the order code designates the NPN output configuration, which sinks current to ground when the sensor detects an object — the standard logic for many PLC input modules that expect a sinking signal.
