Schmersal AZM300B-I2-ST-1P2P-A Electromagnetic Safety Interlock Switch

Product Dimensions：

The Schmersal AZM300B-I2-ST-1P2P-A is an innovative, high-performance electronic solenoid interlock designed for safety-critical industrial environments. It utilizes an unique Maltese cross-shaped locking mechanism and integrated RFID technology to provide maximum protection against tampering and bypass.

Product Detailed Description

The AZM300 series represents a significant leap from traditional mechanical safety switches. This specific model features an individual coding level (I2), meaning it will only operate with a specific actuator it has “learned,” meeting the highest anti-tamper requirements. The “B” in the model name indicates that the actuator is not included and must be ordered separately.

Technical Parameters

Product Advantages

• Tamper Protection: The RFID sensor detects the correct actuator with high precision. The “I2” individual coding prevents employees from bypassing the safety system using a spare actuator.
• Symmetrical Design: The Maltese cross-shaped bolt allows the actuator to enter from three different sides, providing extreme flexibility for both left- and right-handed doors.
• Hygiene & Durability: With its smooth surfaces and IP69 rating, it is resistant to high-pressure washdowns and cleaning agents, making it ideal for food and pharmaceutical industries.
• Adjustable Latching: Even when the guard is unlocked, it has an adjustable latching force to prevent the door from swinging open due to vibration.
• Series Wiring: Multiple AZM300 units can be wired in series without reducing the safety level, simplifying the installation of large machine lines.

Important Considerations (Precautions)

• Power-to-Lock: This model uses the “Power-to-Lock” principle. In the event of a total power failure, the guard will unlock. Ensure this is acceptable based on your machine’s risk assessment (i.e., the machine must stop instantly).
• Actuator Selection: Ensure you purchase the matching AZ/AZM300-B1 actuator, as it is not included with the switch body.
• Alignment: While the Maltese cross is forgiving, excessive mechanical misalignment over time can lead to wear on the locking bolt.
• RFID Teaching: Since this is an individually coded unit (I2), the teaching procedure must be performed during commissioning. Note that there is a limit to the number of times a new actuator can be taught.

Product Applications

The AZM300 is the gold standard for high-security guarding in modern automation:

• Food & Beverage: Bottling lines and packaging machines requiring frequent washdowns.
• Pharmaceutical: Cleanroom environments where smooth, non-contaminating surfaces are required.
• Automotive: Robot cells and assembly lines where high holding forces are necessary to keep heavy guards closed.
• Semiconductor: Precision machinery where small form factors and high-reliability safety signals are critical.
