Why Choose the Pizzato SR AD40AN1 Magnetic Safety Sensor?
The Pizzato SR AD40AN1 is a coded magnetic safety sensor designed for non-contact monitoring of machine guards, doors and protective devices. As part of the Pizzato SR A Series, it uses coded magnetic actuation to provide dependable guard-position monitoring in industrial machinery and safety-related control systems.
The SR AD40AN1 features a robust technopolymer housing, right-side cable connection and 2NC contacts with the guard closed. Its non-contact operating principle avoids mechanical wear between the sensor and actuator, while the coded design helps prevent operation by an ordinary magnet.
Supplied as the sensor without actuator, the SR AD40AN1 is designed for use with the appropriate coded magnetic actuator and safety monitoring module. When incorporated into a correctly designed safety system, the SR A Series can support safety functions up to SIL 3, PL e and Category 4.

Reliable Non-Contact Guard Monitoring
Pizzato SR A Series coded magnetic sensors are designed to monitor guards and protective devices on industrial machinery without mechanical contact. The sensor detects the field generated by the correct coded actuator when the guard is closed and changes the state of its electrical contacts, providing position information to the associated safety system.
For safety applications, the SR AD40AN1 must be connected to an appropriate dual-channel safety module that monitors correct sensor operation. This combination enables reliable machine protection while the wide operating tolerance and resistance to dirt make coded magnetic sensing particularly useful where mechanical alignment can vary during service.
Typical Applications
- Machine guard position monitoring.
- Safety doors and protective access panels.
- Packaging and production machinery.
- Industrial automation equipment.
- Assembly and material handling systems.
- Safety circuits using compatible dual-channel monitoring modules.
