Schmersal AZM200ST2-T-1P2P Safety Locking Device

The Schmersal AZM200ST2-T-1P2P is a RFID-coded safety interlock switch with solenoid guard locking, used in machine safety systems to control and monitor safety doors or protective guards.

It ensures that a machine cannot operate when the guard is open, and can also lock the door until safe conditions are met.

How it works (simple explanation)

This device works like a smart safety door lock with electronic verification:

1. Door closed → RFID actuator detected
2. System checks correct coded key
3. Solenoid locks the door
4. Safety outputs enable machine operation

If:

• Door opens → safety outputs turn OFF
• Wrong or missing actuator → system stays locked or stops machine

Main Functions

• Detects safety door closed/open status
• Prevents machine start when guard is open
• Provides coded anti-tamper protection (RFID)
• Locks door during hazardous machine operation
• Sends safety + diagnostic signals to PLC or safety controller
• Supports series wiring of safety devices

Key Features

• RFID-coded actuator (high anti-bypass protection)
• Dual-channel safety outputs (redundant safety circuit)
• Integrated solenoid guard locking
• Diagnostic LED status indication
• High holding force (up to 2000 N)
• Supports PL e safety systems
• Suitable for complex machine safety networks
