Leuze has expanded its industry-leading safety portfolio with the latest evolution of its LBK 3D Radar Safety System — now enhanced with a fully integrated CIP Safety interface for seamless connection over EtherNet/IP networks. This new capability makes it even easier to achieve certified safety communication and advanced diagnostic transparency while maintaining the rugged reliability customers expect from Leuze.

Reliable in Dust, Smoke, and Harsh Conditions

Built on proven radar technology, the LBK Safety System ensures reliable area monitoring even in the most demanding environments — where dirt, smoke, oil mist, sawdust, or sparks would typically compromise optical safety sensors. Its 3D radar principle detects both moving and stationary personnel, even when partially obscured, ensuring uninterrupted safety coverage. Because static objects such as pallets or containers are ignored, facilities benefit from fewer false alarms and maximized uptime.

Typical application areas include:

• Welding and fabrication

• Wood and paper processing

• Chemical and coating operations

• Heavy industrial manufacturing lines

Seamless Integration with CIP Safety

The LBK’s new CIP Safety interface allows verified safety communication directly over standard EtherNet/IP — without extra gateways. This reduces wiring complexity and facilitates fast implementation into existing plant networks.

Key integration benefits:

• Direct connection to EtherNet/IP networks

• Combined safety and standard data on one infrastructure

• Simplified installation and configuration routines

• Enhanced access to diagnostic and maintenance data

For other environments, controllers remain available with PROFIsafe and FSoE interfaces, ensuring maximum flexibility in multi-platform automation systems.

Scalable, Flexible Coverage

Engineered for modular scalability, a single LBK controller supports up to six radar sensors, with the ability to handle up to 24 sensors when multiple controllers are networked. The LBK Designer configuration software allows customization of both protective and warning fields to precisely match site-specific requirements — including adjustable coverage for AGV pathways, crane movement zones, or material transfer points.

Ideal for Challenging Applications

The LBK 3D Radar Safety System is purpose-built for environments where optical sensing technologies reach their limits. Ideal applications include:

• Guarding hazardous zones in dusty or humid spaces

• Ensuring safety for AGVs, cranes, or mobile systems

• Providing access guarding for dynamically changing work areas

• Enabling reliable restart prevention in automated machinery

Proven Performance and Compliance

The LBK system operates with Performance Level PL d / SIL 2, featuring robust protection (IP67) and operation across -30°C to +60°C. Depending on the model, coverage extends up to 9 meters, with configurable detection angles and frequency options at 24 or 60 GHz.

With these enhancements, Leuze’s LBK 3D Radar Safety System sets a new benchmark in ensuring machine safety under harsh conditions — combining reliability, flexibility, and simplicity in one intelligent radar platform.
