The Schmersal AZM 161-B1 is a mechanical actuator for safety position switches, specifically designed for use with sliding doors and rotating protective devices in industrial automation. The actuator is made of stainless steel, making it suitable for applications in environments with increased requirements for corrosion resistance. It features a straight shape and is intended as a replacement part or addition to existing safety systems.

Applications

The actuator AZM 161-B1 is primarily used in industrial safety technology, particularly with sliding doors and movable protective devices. It serves as a mechanical trigger for safety position switches that monitor the position of the protective device and shut down the machine when it is open or not secured. The application is in machine building, manufacturing technology, and other areas where employee safety must be ensured through mechanical protective devices.

Functions and Equipment in Detail

The actuator is designed for a coding level according to EN ISO 14119 low, meaning it is suitable for applications with low safety requirements, where the hazard from mechanical movement is limited. The stainless steel construction ensures high mechanical strength and long-term durability, especially in moist or corrosive environments. The straight shape of the actuator enables precise and reliable actuation of the safety switch.

Technology Explained Simply

The actuator is mounted on the protective device and moves with it. When the protective device moves (e.g., when opening a sliding door), the actuator is inserted into the switch, enabling the switch to detect its position and respond accordingly. The minimum actuation radii are specified: over the wide side of the actuator, the smallest possible activation distance is 150 mm, and over the narrow side, 180 mm. These specifications are important to ensure that the actuator reliably triggers the switch without the protective device being activated too early or too late. Additionally, the hinge pivot point and the top edge of the safety mounting plus 5 mm must lie in a common plane to ensure correct alignment and function.

Compatibility and Accessories

The actuator AZM 161-B1 is specifically designed for safety position switches. As suitable accessories, the actuator XCSZ12 with wide mounting (length 40 mm) is offered, also intended for safety position switches. Combining it with this accessory allows for adaptable mounting on different protective devices, especially for rotating or pivoting components.

Mounting and Installation

Mounting is done on the protective device, where alignment is critical. The actuator must be positioned so that it correctly activates the safety switch when the protective device is opened. Adhering to the minimum actuation radii and the plane between the pivot point and safety mounting is necessary to ensure reliable function. Mounting is done via the designated mounting points on the actuator.

Advantages in Operation

The actuator AZM 161-B1 provides a robust and reliable mechanical actuation that functions independently of electrical or pneumatic systems. The use of stainless steel ensures long service life and low maintenance. The clear definition of minimum actuation radii and alignment plane simplifies planning and installation, ensuring compliance with safety regulations. Compatibility with additional accessories such as XCSZ12 expands application possibilities and enables flexible adaptation to different machine configurations.
