Turck NI40-G47SR-FZ3X2 Inductive Proximity Switch

The TURCK NI40-G47SR-FZ3X2 Inductive Proximity Switch is a 2‑wire AC/DC, normally open sensor designed for non‑contact metal detection and machine position sensing in harsh industrial environments. It offers a 40 mm sensing distance, a chrome‑plated brass G47 threaded barrel housing with an integral cable for easy installation in non‑flush mounting applications, and is well suited for conveyors, bulk material handling, steel processing machinery, packaging lines, and other heavy automation requiring extended sensing ranges. It operates from 20–250 VAC or 10–300 VDC and can switch up to 400 mA AC or 300 mA DC, allowing direct integration into relay logic and legacy control systems without a separate DC sensor supply. Key features include AC/DC operation, wear‑free switching, short‑circuit protection, and IP67 protection, with an operating temperature range of −25°C to +70°C and a 20 Hz switching frequency. An LED status indicator provides sensing feedback, while common applications encompass end‑of‑travel sensing, position monitoring, and machine sequencing in conveyor systems, mining equipment, pallet handling, and metal fabrication lines.
