SR AL42AN1-A01N Pizzato Safety coded magnetic sensor with actuator

Why Choose the Pizzato SR AL42AN1-A01N Safety Coded Magnetic Sensor with Actuator?

The Pizzato SR AL42AN1-A01N is a compact and reliable coded magnetic safety sensor supplied with actuator, designed for non-contact monitoring of guards, doors and access points on industrial machinery. As part of the Pizzato SR A series, it combines a robust technopolymer sensor housing with the compatible SM A01N coded magnetic actuator for dependable machine safety monitoring.

The SR AL42AN1-A01N uses magnetically operated contacts and features a 1NO+1NC contact configuration with the guard closed. Its non-contact operating principle eliminates direct mechanical contact between the sensor and actuator, helping minimise wear and providing a reliable solution for frequently operated machine guards.

This version features a 1 m oil-resistant PVC cable exiting from the left side of the sensor and is supplied complete with the SM A01N actuator with a 5 mm actuation distance. With IP67 and IP69K protection, the assembly is well suited to demanding industrial environments where reliable guard monitoring and resistance to dust, water and intensive cleaning are important.

Key Advantages

• Complete coded magnetic safety sensor and actuator assembly for machine guarding.
• SM A01N coded actuator included for a complete sensing solution.
• 5 mm actuation distance with the supplied actuator.

• Compact construction for installation on machine guards and access doors.

Reliable Non-Contact Guard Monitoring

Coded magnetic safety sensors such as the Pizzato SR AL42AN1-A01N monitor the position of machine guards without requiring physical contact between the sensor and actuator. When the SM A01N actuator approaches the sensor, the magnetic field operates the internal contacts, allowing the safety control system to determine whether the protected guard is in the required position.

The non-contact design helps minimise mechanical wear and provides greater installation tolerance than conventional mechanically operated safety switches. When incorporated into an appropriately designed safety circuit with compatible safety monitoring equipment, the SR A series provides an effective solution for safeguarding industrial machinery and automated production equipment.

Typical Applications

• Machine guard and access door monitoring.
• Industrial automation equipment.
• Packaging and production machinery.
• Conveyors and material handling systems.
• Machine tools and processing equipment.
• Automated manufacturing cells.
• OEM machinery and machine safety systems.
