SR BD40AN4 Pizzato Safety magnetic sensor

Why Choose the Pizzato SR BD40AN4 Safety Magnetic Sensor?

The Pizzato SR BD40AN4 is a robust safety magnetic sensor designed for reliable non-contact monitoring of guards, doors and protective covers on industrial machinery. As part of the Pizzato SR-B series, it uses magnetic actuation and reed-contact switching to provide dependable guard position detection without the mechanical wear associated with conventional mechanically actuated safety switches.

The sensor features a 2NC contact configuration with the guard closed, providing two normally closed channels for integration with suitable machine safety monitoring equipment. Its durable technopolymer housing incorporates stainless-steel fixing plates for secure installation, while the non-contact operating principle helps maintain reliable performance in machinery subject to frequent guard movement and demanding industrial conditions.

The SR BD40AN4 is supplied with a 4 m oil-resistant PVC cable containing 4 × 0.25 mm² conductors. With IP67 and IP69K protection and suitability for safety functions up to PL e / SIL 3 when correctly integrated into an appropriate safety system, it provides a durable solution for industrial automation and machine guarding applications.

Reliable Non-Contact Guard Monitoring for Industrial Machinery

Magnetic safety sensors such as the Pizzato SR BD40AN4 monitor movable machine guards without requiring physical contact between the sensor and actuator. When the appropriate magnetic actuator enters the sensor's operating range, the reed contacts change state so that the connected safety control system can determine whether the monitored guard is correctly positioned.

The SR-B series is particularly suited to automated machinery where repeated guard movement, contamination or mechanical wear can make conventional mechanically actuated switches less desirable. Its two normally closed contacts, robust technopolymer construction and high environmental protection allow the SR BD40AN4 to be integrated with appropriate safety control equipment for dependable machine guard monitoring.

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.
