SR AL40AN8-A01N Pizzato Safety coded magnetic sensor with actuator

Why Choose the Pizzato SR AL40AN8-A01N Coded Magnetic Safety Sensor?

The Pizzato SR AL40AN8-A01N is a robust coded magnetic safety sensor supplied complete with actuator, designed for non-contact monitoring of movable guards, safety doors and protective covers on industrial machinery. Part of the Pizzato SR-A series, it combines coded magnetic actuation with reliable reed contact technology to provide dependable guard-position monitoring without the mechanical wear associated with conventional mechanically actuated safety switches.

The SR AL40AN8-A01N features a 2NC contact configuration with the monitored guard closed, providing two normally closed reed contacts for integration with suitable machine safety circuits. The coded sensing principle is designed to recognise the corresponding coded actuator rather than an ordinary magnet, helping provide reliable guard monitoring in industrial safety applications.

This version is supplied with a 8 m PVC cable with 4 × 0.25 mm² conductors and the matching SM A01N coded magnetic actuator. It features a left-side cable connection, a 5 mm actuation distance, compact technopolymer construction and IP67 / IP69K protection for dependable operation in demanding industrial environments.

Key Advantages

• Complete coded magnetic safety sensor and actuator set.
• 2NC contact configuration for machine safety monitoring circuits.
• 5 mm actuation distance with the supplied SM A01N coded actuator.
• 8 m PVC cable provides generous installation flexibility on larger machinery.
• Left-side cable connection for machinery requiring this wiring orientation.
• IP67 and IP69K protection for demanding industrial environments.

Reliable Non-Contact Guard Monitoring

Coded magnetic safety sensors monitor the position of movable machine guards without requiring physical contact between the sensor and actuator. When the matching SM A01N coded actuator enters the sensor's operating range, the sensor recognises the actuator and changes the state of its reed contacts, allowing the associated safety control system to determine whether the protective guard is correctly positioned.

The Pizzato SR-A series is designed for industrial machine safety applications where compact construction, reliable switching and resistance to contamination are important. The SR AL40AN8-A01N combines an 8 m pre-wired cable, left-side connection and supplied coded actuator, providing a complete solution for larger machinery installations where the guard sensor may be positioned a significant distance from the associated safety control equipment.

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.
