1. Product Overview
The Schmersal BDF200-ST1-AS-NH-LTGN-LTYE-LTWH-G24 is an advanced 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 tri-color LED indicators (LTGN=Green, LTYE=Yellow, LTWH=White) 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 (G24), 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: 1.8×10⁻⁹/h)
- 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, 6A @ 250V AC)
- Power Consumption: ≤2.5W
- Environmental:
- IP69K (100 bar/80°C washdown)
- Chemical Resistance: Resists pH 1-14 solutions
- LED Indicators:
- LTGN (Green): Guard closed

- UL 508, CE, RoHS
3. Primary Applications
This switch is essential for hazardous area safety:
- Food Processing: CIP system access doors with USDA-compliant sanitation
- Pharmaceutical: Sterile filling line isolators requiring EHEDG certification
- Chemical Plants: Reactor maintenance hatches with acid vapor exposure
- Marine Engineering: Watertight door monitoring on offshore platforms
- Automotive: Robotic welding cell safety gates
- Wastewater Treatment: Sludge tank access covers in corrosive environments
- Mining Equipment: Explosive dust environment guard doors
- Pulp & Paper: Bleach chemical storage access with chlorine resistance
Its triple-LED system enables instant fault diagnosis in low-light areas, while SS316L construction resists chloride-induced stress corrosion cracking (CISC).
4. Functional Advantages

- 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
