1. Product Overview
The Schmersal BNS 36-02Z-R is a hinge-integrated safety switch engineered for swing-guard monitoring in compact spaces. Featuring a 36mm-wide profile with IP67-rated zinc housing, this device utilizes coded magnetic sensing to detect door positions via a specialized rotary hinge actuator (R-suffix). Certified to ISO 13849-1 PL d (Category 3) and IEC 62061 SIL 2, it operates across -30°C to +70°C with resistance to oils, vibrations, and mild chemicals. The integrated hinge pin receiver replaces conventional door pivots, enabling direct mounting without external actuators. Designed for press brakes, packaging machines, and robotic cells, its space-saving design provides ±5mm lateral tolerance while requiring only 120° door opening for safe access.

3. Primary Applications
This hinge-integrated switch excels in confined industrial environments:
- Press Brakes: Space-limited tool area guard monitoring
- Robotic Service Hatches: Swing-door control on collaborative robots
- Packaging Machines: Access panels with <150° opening clearance
- CNC Tool Changers: Guard doors with vibration-induced misalignment
- Inspection Stations: Flip-up safety glass monitoring
- Automotive Assembly: Fixture guarding with restricted lateral space
- Material Handling: Conveyor junction access lids
- Laboratory Ovens: Compact thermal chamber doors
Its unique hinge integration eliminates external actuators, preventing mechanical damage in high-traffic areas while tolerating door sag up to 5mm.

Tool-free magnetic core replacement - Safety Compliance:
- Pre-validated to EN ISO 14119 Type 3
- SIL 2 templates for safety PLCs
5. Safety Operation & Integration
Hinge Monitoring Sequence:
- Door Closure:
- Hinge pin alignment (<120°) closes NC contacts
- Green LED illuminates
- Angle Verification:
- Magnetic field sensors detect 115±5° position
- Auxiliary hall sensors monitor angular deviation
- Fault Management:
-
120° opening forces contacts open
- LED blinking at >105° misalignment
-
- Construction Features:
- Redundant contact springs
- Torsion limiter prevents over-rotation
Technical Architecture:
- Position Detection:
• 3× Hall-effect sensors in 120° array
• Contact closure requires dual-sensor agreement - Failure Modes Mitigated:
• Welded contacts mechanically disconnect output
• Undervoltage lockout below 18V DC
