FESTO SIES-8M-NO-24V-K-0,3-M8D Inductive Sensor, 24V, NO, M8

The SIES-8M-NO-24V-K-0,3-M8D: The normally open (NO) output means the sensor's switch closes when a metal target enters its sensing field. This is the standard configuration for presence detection in a control circuit — the PLC or relay sees a '1' when the target is present. The 24 V DC supply is typical for industrial sensor networks, and the M8 connector with a 0.3 m pigtail cable means it mates directly to a standard M8 male connector on the machine side. The short cable length keeps the signal path clean; if you need to extend it, use a shielded M8 extension cable and ground the shield at the panel end — inductive sensors are susceptible to coupled noise from nearby VFD or motor cables.
