SIL 2/PL d Inductive Safety Sensors
Benefits
Reliable Detection without Dead Band
In contrast to other safety proximity sensors, the inductive safety sensors from Pepperl+Fuchs do not have a dead band. This means that data transfer can occur with no minimum distance. Users can use standard actuator heads without having to adjust the target or machine part.
High Process Safety According to SIL 2/PL d
New safety sensors come with SIL 2 functional safety and PL d Machinery Directive approvals. With redundant implementation, even SIL 3/PL e can be achieved. High characteristic safety values enable easy integration into the safety loop and significantly prolong operating intervals.
Simplified Integration and Handling
A standardized output signal switching device (OSSD) interface opens up direct connection to the safety control or I/O module. Comprehensive safety documentation supports integration. The sensors can be connected via cable or standardized M12 plug.
Designed for Outdoor Use
The portfolio includes four models with different designs (cylindrical, rectangular) and switching distances, creating a wide range of application possibilities. The especially rugged cylindrical versions feature an extended temperature range from -40 °C to +85 °C and an E1 approval—making it the ideal solution for mobile equipment applications.
Optimized Portfolio for Demanding Environments
The optimized sensor series provides with a variety of housing styles and stainless steel models. Discover the new SIL 2/PL d inductive safety sensors from Pepperl+Fuchs that improve safety of both personnel and machinery in your application!

Easy Operation and Reliable Detection without Dead Band
Inductive safety sensors do not require a specifically coded target and can be used with standard metal actuator heads. Due to the fact that they don’t have a dead band, they can be mounted easily and do not need further adjustment. This saves both time and money. Additionally, the standardized OSSD interface enables noncontact safety sensors to be easily and directly connected to the safety controllers.
High Process Safety Time up to SIL 3/PL e
With the new inductive safety sensors, users benefit from high performance and flexible implementation of SIL 2/PL d safety systems. With redundant implementation, even SIL 3/PL e can be achieved. High safety values not only simplify integration into the safety loop, they also ensure that regular testing has to be performed less often, which extends operating intervals. Regular test cycles are now a thing of the past.
Reliable Transport of Trolleys with AGVs
As a smooth material flow is essential for efficient production, automated guided vehicles (AGVs) are increasingly being used to distribute the parts needed at different locations within a plant. Inductive safety sensors ensure that material trolleys are correctly positioned on AGVs.
Level Control at Scissor Lifts in Automotive Production
In automotive production lines, inductive safety sensors are used to reliably detect scissor lifts according to SIL 2/PL d. Once a lift is completely extended, safety sensors check its final position.
Protective Cover Control in Automated Production Processes
Monitored protective covers ensure the safety of on-site personnel for work with presses and machine tools. Inductive sensors continuously ensure that the protective cover is closed before processes can continue.
Bolt Detection on Mobile Cranes
Inductive safety sensors are used on cranes and other mobile equipment. When the telescopic arm of a crane is extended, sensors detect the bolts at the extension mechanism. Further extension is only possible once the safety bolts are detected.
Door Protection in Welding Cells
Inductive safety sensors are used for door protection in welding cells to ensure personal safety. There, they make sure that the welding process is only performed when safety doors are closed.
Inductive Safety Sensors in AGVs and Scissor Lifts
SIL2/PL d rated inductive safety sensors are used wherever men and machine work together in confined spaces—their compact housing makes them ideal for integration into plants or machines such as Automated Guided Vehicles (AGVs).
The standardized OSSD interface allows the devices to be easily and directly connected to existing safety controllers and IO modules. In production lines, inductive safety sensors can be mounted inside scissor lifts where they reliably detect safe end positions.
