Why Choose the Pizzato SR AD40AN3 Magnetic Safety Sensor?
The Pizzato SR AD40AN3 is a robust coded magnetic safety sensor designed for non-contact monitoring of guards, doors and protective covers on industrial machinery. As part of the Pizzato SR-A series, it uses coded magnetic actuation and reed contact technology to provide dependable guard-position monitoring without the mechanical wear associated with conventional mechanically actuated safety switches.
The SR AD40AN3 provides 2 normally closed (2NC) contacts with the monitored guard closed and is designed for use with a compatible coded magnetic actuator. The coded operating principle helps prevent actuation by an ordinary magnet, while non-contact operation makes the sensor particularly suitable for frequently opened machine guards and applications exposed to dirt or contamination.
This version features a 3 m PVC cable with 4 × 0.25 mm² conductors and a right-side cable exit for straightforward integration into industrial machinery. Its durable technopolymer housing provides IP67 and IP69K protection, while the series supports safety systems up to SIL 3 and PL e when correctly integrated with suitable safety control equipment.

Reliable Non-Contact Guard Monitoring
Coded magnetic safety sensors monitor movable machine guards without requiring physical contact between the sensor and actuator. When the correct coded actuator enters the sensor's operating range, the sensor recognises its magnetic field and changes the state of its electrical contacts, allowing the associated safety system to monitor whether the guard is correctly positioned.
The Pizzato SR-A series is designed for industrial safety applications requiring compact construction, reliable switching and resistance to contamination. When the SR AD40AN3 is paired with the compatible SM A01N actuator, the system provides a 5 mm actuation distance, while the 3 m pre-wired cable provides flexibility when routing connections through machinery and control installations.
Typical Applications
- Machine guard and safety door monitoring.
- Protective covers and access panels.
- Automated production and assembly machinery.
- Packaging and processing equipment.
- Conveyors and material handling systems.
- OEM machinery and industrial automation systems.
