SR AD42AN5-A01N Pizzato Safety coded magnetic sensor with actuator

Why Choose the Pizzato SR AD42AN5-A01N Safety Coded Magnetic Sensor?

The Pizzato SR AD42AN5-A01N is a complete coded magnetic safety sensor with actuator designed for non-contact monitoring of guards, doors and protective covers on industrial machinery. Part of the Pizzato SR-A Series, it combines coded magnetic detection with Reed-contact switching for dependable machine guard and safety interlocking applications.

The SR AD42AN5-A01N provides a 1NC + 1NO contact configuration with the protective guard closed. Its coded magnetic operating principle allows the sensor to recognise the corresponding actuator without mechanical contact, helping minimise wear and preventing operation by an ordinary magnet.

This configuration is supplied with the matching actuator providing a nominal 5 mm actuation distance and incorporates a 5 m PVC cable with 4 × 0.25 mm² conductors. The sensor features a right-hand cable exit, robust technopolymer housing, IP67 / IP69K protection and an ambient operating temperature range of -25 °C to +80 °C.

Key Advantages

• Complete coded magnetic safety sensor and actuator for machine guard monitoring.
• 1NC + 1NO contacts with the protective guard closed.
• Nominal 5 mm actuation distance for practical non-contact guard alignment.
• Pre-wired with a generous 5 m PVC cable for flexible machine installation.
• IP67 / IP69K protection for demanding industrial environments.
• Non-contact operation helps reduce mechanical wear during repeated guard movements.

Reliable Non-Contact Guard Monitoring

Coded magnetic safety sensors monitor movable machine guards without requiring physical engagement between the sensor and actuator. When the correct coded actuator enters the sensor's operating zone, the Reed contacts change state so that the guard condition can be evaluated by an appropriately designed safety control system.

The Pizzato SR-A Series is designed for applications where frequent guard movement, contamination or limited mounting space can make conventional mechanically actuated switches less practical. When combined with suitable safety control equipment, SR-A sensors can form part of safety systems reaching up to PL e, SIL 3 and Category 4, subject to the design and validation of the complete safety function.

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.
