1. Extended-Range Non-Contact Safety Sensing
The Schmersal BNS 300-01ZG is an advanced non-contact safety sensor engineered for industrial applications requiring large sensing distances and robust environmental protection. Featuring a glass-fiber reinforced polyamide housing (PA66-GF35), this device utilizes 300mm inductive sensing technology to detect ZG-coded RFID actuators without mechanical contact. Its dual-channel architecture achieves Category 4/PL e (ISO 13849-1) safety integrity with SIL 3 (IEC 62061) compliance through redundant diagnostics and encrypted signal transmission (AES-256). Rated for -40°C to +85°C operation and IP67 protection, it withstands vibration (50 m/s²), oil/coolant exposure, and structural misalignment in demanding environments like steel mills and automotive production lines. The integrated tri-color LED provides instant visual status across long distances.

3. Industrial Applications & Implementation Scenarios
This extended-range sensor excels in heavy industries with structural movement:
- Steel Rolling Mills: Guarding reheat furnace access with ±25mm thermal expansion
- Automotive Assembly Lines: Monitoring 15m-long robotic cell sliding doors
- Port Crane Gantries: Safety interlocks for boom maintenance platforms
- Mining Stacker/Reclaimers: Dust-resistant position feedback for radial conveyors
- Paper Mill Winders: Access control near high-speed rollers
Key advantages include 300mm sensing tolerance eliminating precision alignment needs, encrypted RFID authentication preventing tampering (ISO 14119 Type 4), and marine-grade construction surviving salt spray environments. Case study: Reduced commissioning time by 60% at Hyundai shipyard crane installations.
4. Functional Advantages & Performance Capabilities
- Structural Flexibility Accommodation:
300mm air gap tolerance compensates for ±30mm thermal drift without recalibration - Military-Grade Security:
256-bit rolling RFID encryption prevents signal cloning (IEC 62443 compliance) - Diagnostic Intelligence:
Tri-color LEDs (green=secured, yellow=warning, red=fault) + OSSD pulse-coded feedback - Cross-Industry Voltage Compatibility:
24-240V AC/DC operation eliminates need for voltage converters - Maintenance-Free Operation:
Non-contact technology enables >20M cycles without calibration - Extreme Environment Resilience:
-40°C cold start capability and 85°C ambient tolerance (IEC 60068-2-1/14 validated) - Smart Integration:
PROFIsafe/CIP Safety protocol support via Schmersal AZM 300 controllers
5. Safety Logic & Failure Management Protocol
Operational Sequence:
- Field Detection:
ZG-coded RFID actuator enters 300mm inductive field - Cryptographic Validation:
AES-256 challenge-response protocol authenticates actuator - Position Verification:
Magnetic vector analysis confirms alignment within ±3° tolerance - Output Activation:
Dual OSSDs energize after successful validation
Fault Responses:
- Signal interruption >200ms → immediate de-energization (<25ms)
- Authentication failure → lockout state with unique OSSD pulse code
- Voltage dip <18V → failsafe shutdown
- EMI interference >30V/m → diagnostic fault signaling
Recovery requires manual reset via integrated pushbutton or PLC command after fault clearance.
