1. Product Overview & Core Safety Technology
The Schmersal BNS 120-02Z is a non-contact RFID-coded safety sensor designed for long-range guard door monitoring in industrial automation. Featuring a polyamide housing (PA66-GF30) with IP67 protection, this device utilizes 120mm sensing technology to detect Z-coded RFID actuators without physical contact. The dual-channel architecture achieves Category 4/PL e (ISO 13849-1) safety integrity with SIL 3 (IEC 62061) compliance. Its tamper-proof design prevents defeat attempts through encrypted signal transmission (AES-128 encryption), while the -40°C to +85°C operational range and 100g shock resistance ensure reliability in harsh environments like automotive assembly and material handling systems. Integrated LED diagnostics provide instant status visibility.

3. Industrial Applications & Deployment Scenarios
This sensor excels in large-scale guarding applications:
- Automotive Body Shops: Monitoring 10m-long robotic cell access gates
- Warehouse Loading Docks: Safety interlocks for high-bay storage systems
- Steel Coil Processing Lines: Guarding recoilers with thermal expansion challenges
- Aircraft Assembly Jigs: Position verification in vibration-heavy environments
- Paper Mill Winders: Access control near high-speed rollers
Key advantages include 120mm sensing tolerance accommodating structural flex, RFID anti-tampering meeting ISO 14119 Type 4 requirements, and IP67 sealing surviving hydraulic fluid spray. Case study: Reduced false trips by 68% at BMW assembly line versus mechanical switches.
4. Functional Advantages & Performance Differentiation
- Extended Range Operation:
120mm air gap tolerance eliminates precision alignment requirements - Cyber-Secure Architecture:
Rolling RFID codes prevent actuator cloning (IEC 62443 compliance) - Diagnostic Intelligence:
Tri-color LEDs (green=secured, yellow=misaligned, red=fault) + OSSD pulsing codes - Maintenance-Free Design:
Non-contact sensing enables >10M cycles without calibration - Vibration Immunity:
±3mm position stability at 50Hz vibration (IEC 60068-2-6) - Easy Integration:
M12 quick-connect connectors reduce wiring time by 75% - Cost Efficiency:
Replaces multiple mechanical switches in large guarding systems
5. Safety Function Workflow
Operation follows four-phase logic:
- Actuator Detection:
Z-coded RFID tag enters 120mm sensing field - Authentication:
Validates encrypted 128-bit RFID signature - Position Verification:
Confirms magnetic field symmetry (±5% tolerance) - Output Control:
Dual OSSDs energize only when conditions met
Fault Responses:
- RFID mismatch → shutdown in <15ms
- Signal loss >200ms → latch fault state
- Voltage dip <18V → safe-state de-energization
Recovery requires manual reset via push-button or PLC command.
