Turck NI8-GT18-ADZ30X2-B3331 Proximity Sensor

The TURCK NI8-GT18-ADZ30X2-B3331 is a two-wire AC/DC inductive proximity switch with an 8 mm sensing distance designed for reliable metal-target detection in demanding industrial automation. This S34/S1589 configuration provides a Normally Open (NO) output and a supply range of 20-250 VAC or 10-300 VDC, making it compatible with universal control circuits, while maintenance teams, OEM machine builders, and system integrators rely on it for sensor replacement, automation retrofits, and new equipment installations. Encased in an M18 × 1 threaded barrel with a PTFE-coated brass body (CuZn), it supports non-flush mounting and uses a 7/8" male connector for field wiring. The sensor carries an IP67 protection rating, operates from -25°C to +70°C, and switches at 20 Hz, with built-in reverse polarity, short-circuit, and wire-break protections. Applications include conveyor systems, packaging machinery, material handling equipment, and assembly lines where metal-target detection is essential; it is well-suited for position monitoring, machine sequencing, and pallet handling within automated manufacturing processes.
