Product Short Description
Product Name: Schmersal AZM160-22YP – Safety Door Switch with Actuator, 2 OSSD, M20, Code Actuated, PG9 Cable Gland, Yellow
Product Overview:
The Schmersal AZM160-22YP is a safety interlock switch with coded actuator for machine guarding. Provides 2 OSSD (Output Signal Switching Device) outputs for safety-rated door monitoring. Suitable for safety categories up to PL e / SIL 3.

Functional Features:
- RFID-coded actuator – unique code per lock (prevents substitution)
- 2 OSSD outputs for redundancy monitoring
- LED status indicators (green = OK, red = fault)
- Muting function (via external input)
- Manual release with safety key (optional)
- Fault detection: short circuit, cross-circuit, wire break
Material Composition:
- Switch body: Zinc die-cast, nickel-plated – corrosion resistant
- Actuator: Stainless steel (AISI 316L)
- Coding element: RFID chip (13.56 MHz, ISO 15693)
- Seals: FKM (Viton) O-rings
- Cable gland: Nickel-plated brass, PG9
- Contacts: Gold-plated (Au) for reliable OSSD switching
Structural Features:
- Compact rectangular body: 120 × 70 × 40 mm
- M20 connector on top
- Actuator mounts on door edge (12 mm from edge)
- Mounting: 2 × M6 screws or DIN rail clip
Working Principle:
Actuator (coded) approaches switch → RFID reader verifies code → if valid, magnetic field closes reed contacts → 2 OSSD outputs go HIGH. If actuator removed or wrong code → OSSD outputs go LOW → safety controller stops machine. Muting input allows temporary override.
Advantages:
- Coded actuator prevents tampering (unique RFID per lock)
- 2 OSSD outputs meet highest safety integrity (SIL 3 / PL e)
- IP67/IP69K for washdown environments
- Muting function for production flexibility
Applicable Industries:
- Automotive manufacturing (presses, weld cells)
- Packaging machinery
- Metalworking (CNC, laser cutters)
- Pharmaceutical (cleanroom doors)
- Food processing (washdown)
Installation Requirements:
- Mount switch body on machine frame (2 × M6, torque 5 N·m)
- Mount actuator on door (12 mm from edge, aligned with switch)
- Gap between actuator and switch: 8 ± 2 mm
- Cable: 5-core, min 0.75 mm², shielded
Usage Notes:
- Never bypass OSSD outputs with jumpers – defeats safety function
- Test safety function weekly (per EN ISO 13849)
- Replace actuator only with same-coded unit (document code number)
- Max cable length to safety controller: 100 m (for 250 mA load)
