SR AL42AN10-A01N Pizzato Safety coded magnetic sensor with actuator

Why Choose the Pizzato SR AL42AN10-A01N Safety Coded Magnetic Sensor?

The Pizzato SR AL42AN10-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 compact magnetic safety sensor with its matching coded actuator for machine guarding and safety interlocking applications.

The SR AL42AN10-A01N provides 1NC + 1NO contacts with the protective guard closed using Reed-contact switching technology. Its coded magnetic operating principle enables guard position detection without mechanical engagement between the sensor and actuator, helping minimise mechanical wear in applications where guards are opened and closed frequently.

This configuration has a left-hand connection and an integrated 10 m cable, providing extended wiring reach for installations where the safety control equipment is located away from the monitored guard. The supplied actuator provides a nominal 5 mm actuation distance, while the technopolymer housing and IP67 / IP69K protection support use in demanding industrial environments.

Key Advantages

• Complete coded magnetic safety sensor and actuator for machine guard monitoring.
• 1NC + 1NO contacts with the protective guard closed.

Reliable Non-Contact Guard Monitoring

The SR AL42AN10-A01N uses coded magnetic detection to monitor movable machine guards without requiring physical engagement between the sensor and actuator. When the corresponding coded actuator is 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 design helps minimise mechanical wear and is particularly useful on frequently operated guards and in applications where conventional mechanically actuated switches may be less practical. When correctly incorporated with suitable safety control equipment into a properly designed and validated safety function, the SR-A sensor can support systems achieving up to PL e and SIL 3.

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.
