SR BD41AN1-B01F Pizzato Magnetic safety sensor complete with actuator

Why Choose the Pizzato SR BD41AN1-B01F Magnetic Safety Sensor?

The Pizzato SR BD41AN1-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 1NO + 2NC contact configuration with the guard closed and is supplied complete with the matching SM B01F coded magnetic actuator. Its glass-fibre reinforced technopolymer housing incorporates stainless-steel fixing plates, providing robust construction and secure mounting for demanding machine safety applications.

The SR BD41AN1-B01F is pre-wired with an integrated 1 m PVC cable and the B01F actuator configuration provides a nominal 5 mm actuation distance. With IP67 and IP69K protection, coded actuation and non-contact operation, it is well suited to industrial automation and machinery where reliable safety guard monitoring is required.

Reliable Coded Guard Monitoring for Industrial Automation

Coded magnetic safety sensors such as the Pizzato SR BD41AN1-B01F monitor movable 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 correct magnetic code and changes the state of its electrical contacts, allowing the connected safety control system to monitor whether the 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 correctly incorporated into the machine safety architecture, SR-B coded magnetic sensors can form part of 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.
• OEM machinery and industrial safety systems.
