Why Choose the Pizzato SR BD40AN5 Safety Magnetic Sensor?
The Pizzato SR BD40AN5 is a robust coded magnetic safety sensor designed for reliable non-contact monitoring of guards, doors and access points on industrial machinery. As part of the Pizzato SR-B coded magnetic safety sensor series, it provides dependable guard position detection using a coded magnetic operating principle that avoids mechanical contact between the sensor and actuator.
The SR BD40AN5 features 2NC reed contacts with the guard closed and is designed for use with a compatible Pizzato coded actuator, available separately. Its non-contact operation helps reduce mechanical wear and makes it particularly suitable for frequently operated guards, protective covers and access doors in industrial automation and machine-building applications.
Featuring an integrated 5 m oil-resistant PVC cable, a durable technopolymer housing with stainless steel fixing plates and IP67 / IP69K protection, the SR BD40AN5 is engineered for demanding industrial environments. Compatible actuator options include the SM B01F with a 5 mm actuation distance and SM B02F with an 8 mm actuation distance.

Reliable Non-Contact Safety Monitoring for Industrial Machinery
Coded magnetic safety sensors such as the Pizzato SR BD40AN5 monitor the position of movable machine guards without requiring direct mechanical contact. When a compatible coded actuator enters the sensor's operating range, the magnetic field operates the internal reed contacts, allowing the connected safety control system to determine whether the protected guard is correctly positioned.
The coded operating principle is designed so that the sensor responds to the appropriate actuator rather than relying on mechanical contact. Combined with its 5 m integrated cable, stainless steel fixing plates and high ingress protection, the SR BD40AN5 provides a durable solution for industrial machine safety applications where reliable guard monitoring is required.
Typical Applications
- Industrial machine guard monitoring.
- Safety doors and protective access panels.
- Packaging and production machinery.
- Conveyors and material handling equipment.
- Automated manufacturing cells.
- Machine tools and processing equipment.
- OEM machinery and industrial safety systems.
