SR AL41AN5-A01N Pizzato Safety coded magnetic sensor with actuator

Why Choose the Pizzato SR AL41AN5-A01N Coded Magnetic Safety Sensor?

The Pizzato SR AL41AN5-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 AL41AN5-A01N features a 1NO+2NC contact configuration with the monitored guard closed, providing two normally closed contacts together with one normally open auxiliary contact. This configuration supports machine safety monitoring while also providing an additional contact that can be used for signalling or status monitoring within the control system.

This version is supplied with a 5 m PVC cable with 6 × 0.25 mm² conductors and the matching SM A01N coded magnetic actuator. It features a left-side cable connection, a 5 mm actuation distance, durable technopolymer construction and IP67 / IP69K protection for dependable operation in demanding industrial environments.

Key Advantages

• Complete coded magnetic safety sensor and actuator set.
• 1NO+2NC contact configuration provides safety and auxiliary monitoring contacts.

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 correct actuator and changes the state of its reed contacts, allowing the associated safety control equipment to determine whether the protective guard is correctly positioned.

The Pizzato SR-A series is designed for industrial machine safety applications where reliable switching, resistance to contamination and reduced mechanical wear are important. The SR AL41AN5-A01N combines a versatile 1NO+2NC contact arrangement, 5 m pre-wired cable, left-side connection and supplied coded actuator to provide a complete guard-monitoring solution for industrial machinery.

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.
