Product Overview
The Turck NI100U-K90SR-HG4X2 is a heavy-duty inductive proximity sensor engineered for ultra-long-range, non-contact detection of metallic objects in extreme industrial environments. Featuring a robust stainless steel housing with IP67/IP69K protection, this sensor is designed to withstand harsh conditions such as dust, moisture, high-pressure washdowns, and mechanical impacts. Operating on a 10–30 V DC supply, it delivers a configurable PNP or NPN output via a shielded M12 connector (HG4X2 variant). With an extended sensing range and advanced diagnostics, the NI100U-K90SR-HG4X2 is ideal for applications in heavy machinery, mining, and bulk material handling systems. Its rugged construction ensures seamless integration into Industry 4.0-ready automation networks.
Key Technical Parameters

- Protection Class: IP67/IP69K (dustproof, waterproof, and high-pressure resistant).
- Switching Frequency: Up to 300 Hz for stable performance in dynamic applications.
- Connector: M12 4-pin shielded (HG4X2 variant) with PUR/PVC cable options.
- Certifications: CE, UL, cULus, RoHS, and IECEx compliance.
Typical Applications
The NI100U-K90SR-HG4X2 is tailored for industries requiring ultra-long-range sensing and extreme durability:
- Mining: Detecting oversized metal equipment, conveyor components, or drilling machinery in dusty, vibration-heavy environments.
- Steel Production: Monitoring rolled steel plates, coils, or furnace components in high-temperature zones.
- Bulk Material Handling: Position sensing of large metal pallets, cranes, or automated storage systems.
- Heavy Machinery: Ensuring safety interlocks for hydraulic systems or rotating equipment in construction vehicles.
- Energy: Detecting metal structures in wind turbine installations or oil and gas pipelines.
Its extended range and rugged design make it indispensable for critical infrastructure applications.
Competitive Advantages
- Ultra-Long Sensing Range: 100 mm detection capability for large or irregular targets.
- Extreme Environment Resilience: 316L stainless steel housing resists corrosion, abrasion, and thermal stress.
- Flexible Integration: Configurable outputs and shielded connectors adapt to diverse control systems.
- Quick Installation: Pre-wired M12 connectors and threaded mounting minimize downtime.
- Smart Diagnostics: Dual-color LEDs (power/status) and IO-Link compatibility (if applicable) enable predictive maintenance.
Core Functionalities
The NI100U-K90SR-HG4X2 delivers advanced industrial-grade features:
- Adjustable Sensitivity: Teach-in function or potentiometer for precise threshold calibration.
- EMI/RFI Shielding: Ensures stable performance near motors, inverters, or high-voltage equipment.
- Fail-Safe Design: Short-circuit and overload protection safeguards connected PLCs and controllers.
- Temperature Compensation: Maintains accuracy across extreme thermal fluctuations.
- Explosion-Proof Compliance: IECEx certification enables use in hazardous areas (Zone 21/22).
