1. Product Overview
The Schmersal BDF200-ST1-AS-NH-LMRD-LTWH-LTBU is a premium stainless-steel safety switch engineered for critical access control in extreme industrial environments. Featuring a Type 4 magnetic interlock system, this IP69K-rated device combines a stainless steel housing (ST1) with a separate actuator head (AS) for flexible mounting configurations. The switch incorporates triple-color LED indicators (LMRD=Red, LTWH=White, LTBU=Blue) providing multi-status diagnostics visible from multiple angles. Designed for SIL 3/PL e applications per ISO 13849-1, it utilizes force-guided normally closed contacts (NH) with redundant monitoring circuits. Operating at 24V DC, the switch withstands temperatures from -30°C to +80°C and resists high-pressure washdowns (100 bar), chemicals, and corrosive atmospheres. The magnetic non-contact operation ensures >10 million maintenance-free cycles.
2. Key Technical Parameters
- Safety Ratings:
- ISO 13849-1 PL e (Category 4)
- IEC 62061 SIL 3 (PFHD: 2.1×10⁻⁹/h)
- PLe/SIL 3 certified
- Construction:
- Housing: SS316L stainless steel
- Actuator Gap: 0–3mm lateral tolerance
- Impact Protection: IK10 (20J)
- Electrical:
- Voltage: 24V DC ±10%
- Contacts: 2 NC (force-guided)
- Current Rating: 6A @ 250V AC / 8A @ 24V DC
- Environmental:
- IP69K (100 bar/80°C washdown)
- Chemical Resistance: Resists pH 1-14 solutions
- LED Indicators:
- LMRD (Red): Fault/Actuator misalignment
- LTWH (White): Power status
- LTBU (Blue): Guard closed status
- Certifications:
- ATEX/IECEx Zone 21/22
- UL 508, CSA C22.2 No. 14
3. Primary Applications
This switch is essential for hazardous area safety:
- Food Processing: CIP/SIP system access doors in meat/poultry plants
- Pharmaceutical: Sterile filling line isolator hatches
- Chemical Plants: Reactor maintenance hatches with acid vapor exposure
- Marine Engineering: Watertight door monitoring on offshore platforms
- Automotive: Paint shop robotic cell safety gates
- Wastewater Treatment: Sludge tank access covers
- Mining Equipment: Explosive dust environment guard doors
- Pulp & Paper: Bleach chemical storage access
Its triple-LED system enables instant fault diagnosis in low-light areas, while SS316L construction resists chloride-induced stress corrosion cracking (CISC) in coastal environments.
4. Functional Advantages
- Multi-Status Diagnostics:
- Red LED: Actuator misalignment >1mm or contact fault
- White LED: Power supply health
- Blue LED: Positive guard closure confirmation
- Corrosion Defense:
- Passivated SS316L housing
- Crevice-free design (EN 1672-2 compliant)
- Tamper Resistance:
- Anti-magnetic shielding defeats external magnets
- Torque-monitored security screws (5Nm)
- Installation Flexibility:
- ±3mm lateral tolerance for door/warpage compensation
- 360° visible LEDs
- Safety Redundancy:
- Dual-channel monitoring with cross-fault detection
- Positive-break contacts (EN 60947-5-1)
- Lifecycle Benefits:
- 10-year lubricant-free operation
- Hot-swappable actuator replacement
5. Safety Operation & Diagnostics
Magnetic Interlock Sequence:
- Guard Closure:
- Actuator aligns within 3mm of sensor face
- Reed contacts close via magnetic field
- Safety Circuit Activation:
- NC contacts close to enable machine operation
- Blue LED illuminates
- Continuous Monitoring:
- Hall sensors verify actuator position (±0.3mm)
- Current monitoring detects contact welding
- Fault Response:
- Actuator displacement >1mm: Red LED + contact opening
- Contact welding: Forces redundant contact open
Diagnostic Hierarchy:
- Priority 1 (Red LED):
- Actuator misalignment
- Contact failure
- Supply voltage <20V DC
- Priority 2 (Blue LED OFF):
- Guard open while machine running
- Priority 3 (White LED OFF):
- Power loss
Reset Protocol:
- Manual actuator removal/reinsertion required after faults
- System performs self-test before restart
