1. Product Overview & Core Technology
The Schmersal BNS 300-01ZG-ST is an ultra-long-range non-contact safety sensor engineered for large-scale industrial guarding where structural flex or thermal drift exceeds standard tolerances. Featuring a marine-grade AISI 316L stainless steel housing, this device utilizes 300mm inductive sensing technology to detect ZG-ST encrypted RFID actuators without mechanical linkage. The "01ZG" suffix denotes military-grade AES-256 encryption and IP69K-rated sealing, achieving Category 4/PL e (ISO 13849-1) and SIL 3 (IEC 62061) compliance. Rated for -40°C to +85°C operation and 100g shock resistance (IEC 60068-2-27), it withstands high-pressure washdowns, salt spray, and chemical exposure in offshore, mining, and heavy manufacturing applications. Dual OSSD outputs with cross-monitoring ensure failsafe machine shutdown within 25ms.
2. Critical Technical Specifications

3. Industrial Applications & Deployment Scenarios
This sensor excels in extreme environments with dynamic structures:
- Offshore Crane Luffing Mechanisms: Safety monitoring on FPSO vessels with ±25mm structural deflection
- Steel Plate Rolling Mills: Guarding reheat furnaces with 300°C radiant heat
- Mining Stacker Conveyors: Dust-ingress proof position feedback
- Chemical Tanker Loading Arms: Zone 1 hazardous area compliance
- Hydraulic Press Platens: Guarding 10,000-ton stamping presses with thermal drift
Key advantages include 300mm sensing tolerance accommodating seismic shifts, encrypted ZG-ST actuators defeating tampering (ISO 14119 Type 4), and 316L construction resisting pitting corrosion. Case study: Eliminated alignment-related downtime at ArcelorMittal hot strip mill.
4. Functional Advantages & Performance Differentiation
- Structural Flexibility Accommodation:
300mm air gap tolerates ±30mm thermal expansion without recalibration - Cybersecurity Architecture:
Rolling 256-bit RFID encryption (IEC 62443-3-3 Level 2) - Predictive Diagnostics:
OSSD pulse coding identifies 12+ fault types (e.g., 3 pulses = EMI interference) - Cross-Industry Voltage Compatibility:
24-240V AC/DC operation replaces voltage converters - Marine-Grade Durability:
1,000hr salt spray resistance (ISO 9227 DA Level) - Lifecycle Economy:
25M+ operation cycles (5× mechanical switch lifespan) - Smart Integration:
PROFIsafe/CIP Safety protocols via Schmersal AZM 400 gateways
5. Safety Logic & Failure Management
Operational Sequence:
- Field Activation:
ZG-ST actuator enters 300mm RF field - Cryptographic Handshake:
AES-256 challenge-response authentication - Vector Validation:
Magnetic flux symmetry analysis (±3% tolerance) - Output Control:
Dual OSSDs energize after validation
Critical Fault Responses:
- Authentication failure → shutdown in <20ms
- Signal loss >150ms → latch fault state
- Voltage dip <18V → safe-state de-energization
- EMI >30V/m → diagnostic pulsing (OSSD code 7)
Recovery requires manual reset via pushbutton or PLC command.
