Product Overview
The Turck BI8U-M18E-AP6X-H1141 is a rugged inductive proximity sensor designed for high-precision, non-contact detection of metallic objects in demanding industrial environments. Featuring an M18 stainless steel housing with IP67/IP69K protection, this sensor is built to withstand harsh conditions such as dust, moisture, mechanical shocks, and high-pressure washdowns. Operating on a 10–30 V DC supply, it delivers a configurable PNP or NPN output via a shielded M12 connector (AP6X variant). The BI8U-M18E-AP6X-H1141 is ideal for applications requiring repeatable accuracy, durability, and seamless integration into automation systems, such as automotive manufacturing, material handling, and food processing. Its advanced diagnostics and compact design make it suitable for Industry 4.0-ready networks.
Key Technical Parameters
- Sensing Range: 8 mm (for mild steel; reduced for non-ferrous metals).
- Supply Voltage: 10–30 V DC (±10%) with reverse polarity and surge protection.
- Output Type: Configurable PNP/NPN transistor (NO/NC), 200 mA max load current.
- Housing Material: Stainless steel (316L) with anti-corrosion coating.
- Operating Temperature: -25°C to +85°C (-13°F to +185°F).
- Protection Class: IP67/IP69K (dustproof, waterproof, and resistant to high-pressure cleaning).
- Switching Frequency: Up to 1 kHz for rapid response in dynamic applications.
- Connector: M12 4-pin shielded (AP6X variant) with PUR cable (H1141 configuration).
- Certifications: CE, UL, cULus, RoHS, and REACH compliance.
Typical Applications
The BI8U-M18E-AP6X-H1141 excels in industrial automation scenarios requiring robust sensing solutions:
- Automotive Assembly: Detecting metal components in robotic welding, stamping presses, or conveyor systems.
- Packaging Machinery: Verifying the presence of metal lids, cans, or foil seals on high-speed filling lines.
- Food & Beverage: Monitoring stainless steel valves, mixers, or conveyor chains in sanitary washdown zones.
- Material Handling: Position feedback for automated guided vehicles (AGVs) or palletizing systems.
- Heavy Machinery: Ensuring safety interlocks for hydraulic cylinders or rotating equipment.
Its immunity to electromagnetic interference (EMI) guarantees stable performance near motors, inverters, or welding systems.
Competitive Advantages
- Extreme Durability: 316L stainless steel housing resists corrosion, chemicals, and mechanical stress.
- High Sensing Accuracy: Consistent 8 mm range with minimal hysteresis for reliable detection of small or thin targets.
- Quick Installation: Pre-wired M12 connectors and threaded design minimize setup time and maintenance.
- Flexible Configuration: Configurable output logic (PNP/NPN) adapts to diverse control systems.
- Long Lifespan: Hermetic sealing and robust construction reduce downtime in high-cycle operations.
Core Functionalities
The BI8U-M18E-AP6X-H1141 delivers advanced features for industrial reliability:
- Short-Circuit Protection: Automatic shutdown safeguards against wiring faults or overloads.
- Diagnostic LEDs: Dual-color indicators (green for power, yellow for output status) enable rapid troubleshooting.
- Temperature Stability: Maintains performance across extreme thermal conditions.
- IO-Link Compatibility (if applicable): Enables remote parameterization, diagnostics, and firmware updates.
- Vibration Resistance: Secure M12 connection ensures uninterrupted operation in high-vibration environments.
