SR AL40AN7-A01N Pizzato Safety coded magnetic sensor with actuator

Why Choose the Pizzato SR AL40AN7-A01N Safety Coded Magnetic Sensor?

The Pizzato SR AL40AN7-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 its corresponding actuator to provide a complete solution for machine guard monitoring and safety interlocking applications.

The SR AL40AN7-A01N provides 2NC contacts with the protective guard closed and uses Reed-contact switching with coded magnetic actuation. Its non-contact operating principle avoids mechanical engagement between the sensor and actuator, helping minimise wear while providing dependable guard position detection in frequently operated industrial machinery.

This configuration features a left-hand connection and an integrated 7 m PVC cable with 4 × 0.25 mm² conductors. The supplied coded actuator provides a nominal 5 mm actuation distance, while the technopolymer housing, IP67 / IP69K protection and -25 °C to +80 °C ambient operating temperature range support installation in demanding industrial environments.

Key Advantages

• Complete coded magnetic safety sensor and actuator for machine guard monitoring.
• 2NC contacts with the protective guard closed.
• Nominal 5 mm actuation distance for reliable non-contact guard detection.
• Integrated 7 m PVC cable provides extended reach to remotely positioned safety control equipment.
• Left-hand cable exit suits installations requiring wiring from the left side of the sensor.
• IP67 / IP69K protection supports demanding industrial environments.
• Non-contact operation helps minimise mechanical wear during repeated guard movements.

Reliable Non-Contact Guard Monitoring

The SR AL40AN7-A01N uses coded magnetic detection to monitor movable machine guards without physical engagement between the sensor and actuator. When the correct coded actuator is positioned within the operating zone, the sensor recognises it and changes the state of its Reed contacts so that the guard condition can be evaluated by suitable machine safety control equipment.

When combined with an appropriate safety module and incorporated into a correctly designed and validated safety system, SR-A coded magnetic sensors can support safety architectures up to SIL 3, PL e and Category 4. The generous 7 m integrated cable on this configuration also provides additional installation flexibility where the monitored guard is positioned some distance from the associated safety control equipment.

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.
