SR BD41AN4-B01F Pizzato Magnetic safety sensor complete with actuator

Why Choose the Pizzato SR BD41AN4-B01F Magnetic Safety Sensor?

The Pizzato SR BD41AN4-B01F is a coded magnetic safety sensor complete with actuator designed for reliable non-contact monitoring of guards, doors and protective covers on industrial machinery. Part of the Pizzato SR-B series, it combines coded magnetic actuation with reed-contact switching to provide dependable guard position detection without requiring mechanical contact between the sensor and actuator.

The sensor features a 2NC + 1NO contact configuration with the guard closed and is supplied complete with the matching SM B01F coded magnetic actuator. The coded operating principle allows the sensor to recognise the correct actuator rather than an ordinary magnet, while its technopolymer housing and stainless-steel fixing plates provide robust construction for industrial machine safety applications.

The SR BD41AN4-B01F is pre-wired with an integrated 4 m PVC cable and operates from 24 V AC/DC. The supplied SM B01F actuator provides a 5 mm actuation distance, while IP67 and IP69K protection supports dependable operation in demanding industrial environments.

Reliable Coded Guard Monitoring for Industrial Automation

Coded magnetic safety sensors such as the Pizzato SR BD41AN4-B01F monitor movable machine guards without requiring physical contact between the sensor and actuator. When the supplied SM B01F coded actuator enters the sensor's operating range, the sensor recognises the actuator and changes the state of its reed contacts, allowing the connected safety control equipment to determine whether the monitored guard is correctly positioned.

The SR-B series is particularly suited to automated machinery where frequent guard movement, contamination or mechanical wear can make conventional mechanically actuated switches less desirable. When connected to an appropriate safety module and incorporated into a correctly designed safety architecture, the SR BD41AN4-B01F can form part of machine safety systems designed to achieve up to PL e, SIL 3 and Category 4.

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.
• Robotic cells and guarded automation systems.
• OEM machinery and industrial safety systems.
