Why Choose the Pizzato SR AL41AN4-A01N Safety Coded Magnetic Sensor?
The Pizzato SR AL41AN4-A01N is a complete coded magnetic safety sensor with actuator designed for reliable non-contact monitoring of guards, doors and protective covers on industrial machinery. Part of the Pizzato SR-A Series, it combines a coded magnetic sensor with the matching SM A01N actuator to provide a complete guard-monitoring solution.
The SR AL41AN4-A01N provides a 2NC + 1NO contact configuration with the protective guard closed. Its coded magnetic operating principle enables the position of the corresponding actuator to be detected without mechanical engagement, helping minimise mechanical wear in applications where machine guards are opened and closed frequently.
This configuration features a left-hand connection and an integrated 4 m PVC cable with 6 × 0.25 mm² conductors. The supplied SM A01N coded actuator provides a nominal 5 mm actuation distance, while the durable technopolymer housing and IP67 / IP69K protection support installation in demanding industrial environments.

Reliable Non-Contact Guard Monitoring
The SR AL41AN4-A01N uses coded magnetic detection to monitor movable machine guards without requiring physical engagement between the sensor and actuator. When the supplied SM A01N actuator is correctly positioned within the operating zone, the sensor's Reed contacts change state so that the guard condition can be evaluated by suitable machine safety control equipment.
The non-contact operating principle helps reduce mechanical wear and makes SR-A sensors particularly useful on frequently operated guards and in environments where contamination can make conventional mechanically actuated switches less convenient. The 4 m integrated cable and left-hand connection also provide practical installation flexibility across a wide range of industrial machinery.
Typical Applications
- Industrial machine safety guards.
- Hinged and sliding safety doors.
- Protective covers and removable access panels.
- Packaging and processing machinery.
- Automated assembly and production equipment.
- Material handling and manufacturing systems.
