Why Choose the Pizzato SR AL42AN4 Magnetic Safety Sensor?
The Pizzato SR AL42AN4 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 switching to provide dependable guard position detection for industrial machine safety applications.
The sensor features a robust technopolymer housing with the electrical connection positioned on the left. Its non-contact operating principle eliminates mechanical contact between the sensor and actuator, helping minimise wear while supporting reliable operation in machinery subject to frequent guard movement, contamination and demanding operating conditions.
The SR AL42AN4 provides a 1NC + 1NO contact configuration with the guard closed and is pre-wired with a 4 m oil-resistant PVC cable. Designed for 24 V AC/DC safety circuits and offering IP67 protection, it provides a practical solution for automated production equipment, machine guarding and industrial safety systems.

Reliable Non-Contact Guard Monitoring for Industrial Machinery
Coded magnetic safety sensors such as the Pizzato SR AL42AN4 monitor movable machine guards without requiring mechanical contact between the sensor and actuator. When the appropriate magnetic actuator enters the sensor's operating range, the reed contacts change state so the connected safety control system can determine whether the monitored guard is correctly positioned.
The SR-A series is particularly suitable for automated machinery where repeated guard operation, contamination or mechanical wear can make conventional mechanically actuated switches less desirable. Its compact technopolymer construction, magnetic operating principle and pre-wired cable connection provide straightforward integration into modern industrial machine safety systems.
Typical Applications
- Industrial machine guard monitoring.
- Safety doors and protective access panels.
- Packaging and processing machinery.
- Automated assembly and production equipment.
- Conveyor and material handling systems.
- OEM machinery and industrial safety systems.
