Why Choose the Pizzato SR BD42AN4 Safety Magnetic Sensor?
The Pizzato SR BD42AN4 is a robust coded magnetic safety sensor designed for non-contact monitoring of guards, doors and access points on industrial machinery. As part of the Pizzato SR B series, it provides dependable machine safety monitoring for industrial automation, production equipment and machine guarding applications.
The sensor uses magnetic actuation with Reed contact switching to detect the position of a movable guard without requiring direct mechanical contact. Its technopolymer housing with metal fixing plates and high environmental protection make it suitable for demanding industrial installations where contamination, moisture and repeated guard operation may be encountered.
The SR BD42AN4 features 1NC + 1NO contacts with the guard closed and an integrated 4 m cable. This version is supplied without an actuator, allowing a compatible actuator to be selected separately to suit the required installation and operating distance. With IP67 and IP69K protection, the sensor is suitable for dusty, wet and washdown environments.

Reliable Non-Contact Safety Monitoring
Magnetic safety sensors such as the Pizzato SR B series monitor movable machine guards without requiring physical contact between the sensor and actuator. When a compatible coded magnetic actuator enters the operating range of the sensor, its Reed contacts change state so that a suitable safety control system can determine whether the guard is correctly closed.
The SR BD42AN4 combines non-contact operation with a durable technopolymer housing, metal fixing plates and high ingress protection. This makes it particularly suitable for industrial machinery where dirt, moisture, repeated guard movements or alignment requirements can make conventional mechanically actuated safety switches less suitable.
Typical Applications
- Machine guard and access door monitoring.
- Industrial automation equipment.
- Packaging and production machinery.
- Food and beverage processing equipment.
- Material handling and conveyor systems.
- Automated manufacturing cells.
- Machinery operating in wet, dusty or washdown environments.
- OEM machinery and industrial safety systems.
