Turck NI8-S18-AZ3X Inductive Proximity Sensor

Turck NI8-S18-AZ3X is an inductive proximity sensor from Turck that detects metal targets without physical contact. The product data identifies the model NI8-S18-AZ3X and notes a 300 VDC rating (S100 300VDC) for this part. Inductive proximity sensors generate an electromagnetic field and sense disturbances caused by nearby metal objects, enabling non-contact presence or position sensing in automated systems. They are used in automation to detect metal parts, components, or tooling and to trigger control actions without wear from movement or contact. The NI8-S18-AZ3X designation places this unit within Turck’s industrial sensing lineup, providing a metal-detection capability in applications where non-contact sensing is required.
