Schmersal AZM200 STS30L-2616-2 Safety Interlock Switch

The Schmersal AZM200 STS30L-2616-2 is a safety interlock switch with solenoid guard locking, designed for machine safety door monitoring and access control in industrial automation systems.

It ensures that a machine cannot operate when a safety guard door is open, and it can also lock the door until hazardous motion has stopped.

How it works (simple explanation)

This device acts as a smart safety door lock:

Door closed + correct actuator inserted
↓
System allows machine operation

Door opened or unlocked
↓
Safety outputs turn OFF
↓
PLC safety system stops machine

If equipped with locking:

• Door stays physically locked until safe condition is met

Main Functions

• Detects safety door open/close status
• Prevents machine start when guard is open
• Locks door during dangerous machine movement
• Provides safety-rated feedback signals to safety PLC or relay
• Prevents bypass using coded RFID actuator

Features & Advantages

• RFID-coded actuator prevents tampering
• Dual-channel safety output (redundant safety logic)
• High holding force door locking
• Diagnostic outputs for PLC monitoring
• Series-wiring capability in safety circuits
• Designed for high safety performance (PL e capable system design)
• Suitable for complex machine guarding systems
