Turck NI20U-M30-AP6X - IP67 20mm Universal - Industrial Large-Bore Stainless - Inductive Proximity Sensor

The Turck NI20U-M30-AP6X is a heavy-duty inductive proximity sensor engineered for reliable non-contact detection of metallic objects in extreme industrial environments. Featuring a robust M30 stainless steel housing with IP67/IP69K protection, this sensor is designed to withstand harsh conditions, including exposure to dust, moisture, high-pressure washdowns, and mechanical impacts.
Operating on a 10-30 V DC supply, it provides a configurable PNP or NPN output via a shielded M12 connector (AP6X variant). The NI20U-M30-AP6X is optimized for applications requiring extended sensing ranges and high repeatability, such as automotive manufacturing, heavy machinery, and bulk material handling systems. Its rugged construction and advanced diagnostics ensure seamless integration into Industry 4.0-ready automation networks.
