Leuze

Leuze is a sensor and safety technology manufacturer whose products are used to detect, identify, and protect across automated industrial environments. Leuze hardware covers safety laser scanners, photoelectric sensors, optical data transmission systems, and related detection and guarding technology, and is widely installed in intralogistics, manufacturing, and material handling applications where reliable detection and personnel safety are operational requirements. PLC Direct supplies Leuze sensors and safety hardware for customers sourcing replacement components and installed-base parts to maintain existing Leuze-equipped systems.

Why Choose Leuze Sensor and Safety Products

Leuze is recognized for its sensor and safety product range, designed to address detection and area-protection challenges in automated industrial environments. Leuze products are built for applications that require reliable object detection, precise position measurement, or certified safety area monitoring to keep automated systems running safely and productively.

Leuze sensors and safety systems are commonly installed in:

• Automated warehouses and distribution centers with conveyor sorting and routing systems

• Automotive and discrete manufacturing with robotic work cells requiring personnel guarding

• Intralogistics operations running automated guided vehicles (AGVs) and autonomous mobile robots (AMRs)

• Packaging and palletizing lines requiring object detection and product differentiation

• Machine guarding applications where area protection around hazardous equipment is required

• Food and beverage processing environments with hygiene-sensitive detection requirements

• General manufacturing with optical sensing for presence, position, and counting applications

This presence across logistics and manufacturing reflects Leuze's focus on sensor products that combine reliable detection performance with the safety ratings required for personnel protection in automated environments.

Leuze Products and Solutions

Leuze hardware at PLC Direct covers safety laser scanners and photoelectric sensing products used in industrial detection and safety applications. The Leuze collection focuses on hardware that supports the maintenance and operational continuity of installed Leuze sensor and safety systems.

Leuze Product Families

• RSL420 Safety Laser Scanners: The RSL420 series consists of Type 3 safety laser scanners with a 270-degree scanning angle, designed for area protection and access guarding in automated environments. Operating at 24 VDC with IP65 protection, RSL420 scanners support up to 10 protective field pairs (reversible), dynamic contactor monitoring (EDM), and four-field mode for flexible guarding configurations. They are used in machine area guarding, AGV and AMR perimeter protection, and access control around hazardous equipment. Three variants are confirmed in the PLC Direct collection: the RSL420PM, a performance platform variant optimized for AGV and AMR mobile applications; the RSL420-M, with an operating range of 0 to 4.5 m for stationary and mobile guarding; and the RSL420-L, covering larger operating ranges for area protection applications.

• RK Series Retroreflective Photoelectric Sensors: Retroreflective photoelectric sensors for object presence detection across industrial applications. The collection includes the RK18, RK46, RK46C, and RK93 series in multiple variants covering different sensing ranges, output types, and connector configurations. Confirmed part numbers include RK18B-T2, RK318WK, RK46CDL34P200M12, RK46C-DXL3, RK46C-DXL3P2, RK93150L, and RK93S302104. These sensors are used in conveyor detection, packaging line gap sensing, and general presence detection, where a reflector is installed opposite the sensor unit.
