SR AD41AN4 Pizzato Magnetic safety sensor

Why Choose the Pizzato SR AD41AN4 Magnetic Safety Sensor?

The Pizzato SR AD41AN4 is a compact and reliable 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 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 AD41AN4 features a 2NC+1NO contact configuration with the monitored guard closed, providing two normally closed contacts together with an additional normally open contact for safety and auxiliary monitoring functions. Its non-contact operating principle makes it particularly suitable for frequently operated machine guards and industrial applications where dependable position monitoring is required.

This version features a 4 m PVC cable with 6 × 0.25 mm² conductors and a right-side cable connection. The sensor uses a robust technopolymer housing with IP67 protection and is suitable for safety functions up to SIL 3 and PL e when correctly integrated with appropriate safety control equipment.

Key Advantages

• Non-contact magnetic safety sensing for industrial machine guards.
• 2NC+1NO contact configuration provides safety and auxiliary switching contacts.
• 4 m PVC cable provides flexibility for machine installation and wiring.
• Reliable reed contact switching technology.
• Robust IP67 technopolymer housing for demanding industrial environments.
• Suitable for safety functions up to SIL 3 and PL e when correctly integrated.

Key Features

• Pizzato SR-A magnetic safety sensor series.
• 2 normally closed + 1 normally open (2NC+1NO) contacts with the guard closed.
• Reed contact switching technology.
• Non-contact magnetic actuation.
• 4 m PVC connection cable.
• 6 × 0.25 mm² cable conductors.
• Right-side electrical connection.
• Compact block-style technopolymer housing.
• IP67 protection rating.
• No integrated status indicator.
• Designed for use with a compatible Pizzato coded magnetic actuator.

Reliable Non-Contact Guard Monitoring

Magnetic safety sensors monitor the position of movable machine guards without requiring physical contact between the sensor and actuator. When a compatible magnetic actuator enters the sensor's operating range, the reed contacts change state, allowing the associated safety control system to determine whether the protected guard is correctly positioned.

The Pizzato SR-A series is designed for industrial safety applications where compact construction, reliable switching and resistance to demanding operating conditions are important. The SR AD41AN4 combines three reed contacts with a 4 m pre-wired cable, making it a practical choice for machinery requiring two normally closed safety contacts together with an additional normally open monitoring contact.

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.
