Thru-Beam Sensors
• Thru-beam sensors consist of an emitter and a receiver positioned directly opposite each other, allowing light to travel straight from the emitter to the receiver. This configuration provides significant advantages, including long sensing distances and high excess gain, which improves detection reliability. Because the system detects interruptions in the light beam, it can reliably identify nearly any type of object. External factors such as the angle of incidence, surface texture, or color of the object have minimal impact on performance. As a result, thru-beam sensors are widely used in industrial applications where consistent and accurate object detection is essential.

Retroreflective Sensors
• Retroreflective sensors integrate both the emitter and receiver into a single housing, making installation simple and efficient. A reflector is placed opposite the sensor, allowing emitted light to bounce back for detection. This setup reduces alignment complexity while maintaining reliable performance. Standard models with polarization filters enhance accuracy by enabling detection of reflective surfaces without false signals. These sensors also support long sensing distances, making them suitable for various industrial applications. Specialized versions are designed for clear object detection, allowing consistent identification of transparent materials such as glass or plastic, which are typically difficult for conventional sensors to detect reliably.

Diffuse Mode Sensors
• Diffuse mode sensors are easy to install because they require only a single device and no reflector. They detect objects by sensing light reflected directly from the target, making them ideal for short-range applications. These sensors offer high switching accuracy and can reliably identify very small objects. Advanced versions include background suppression, which allows the sensor to focus only on a defined detection zone while ignoring unwanted background signals. Additionally, models with background evaluation are designed for applications with a fixed background, helping ensure proper alignment and stable detection performance in consistent industrial environments.

Fiber Optic Sensors
• Fiber optic sensors and cables are ideal for applications where direct sensor installation is difficult or impossible due to limited space, high temperatures, or harsh environmental conditions. These systems use flexible fiber optic cables to transmit light between the sensing point and the main sensor unit, allowing for remote detection. Their compact and adaptable design makes them especially useful in tight or complex machine setups. Additionally, the fine fiber optic beams enable precise detection of very small objects, making them suitable for high-accuracy tasks in industries such as electronics, automation, and precision manufacturing environments.

Print Mark Sensors
• Print mark sensors from Pepperl+Fuchs are specialized solutions designed for precise detection tasks in specific industrial applications. This category includes both contrast sensors and color sensors, which are engineered to identify printed marks, labels, or color differences on various materials. These sensors are particularly valuable in industries such as printing, packaging, and food processing, where accurate positioning and alignment are critical. By ensuring reliable detection of print marks at high speeds, they help improve production efficiency, reduce errors, and maintain consistent product quality in automated manufacturing and packaging processes.

Distance Sensors
• Distance sensors from Pepperl+Fuchs provide reliable measurement solutions for both short and long-range applications. For long distances, sensors equipped with Pulse Ranging Technology (PRT) use powerful laser pulses to ensure accurate and consistent detection, even in challenging environmental conditions. This makes them suitable for demanding industrial settings where precision is critical. For short-range measurements, sensors utilizing Multipixel Technology (MPT) deliver exceptional accuracy and fine resolution. Together, these technologies offer flexible and high-performance distance sensing options, supporting a wide range of industrial automation tasks with dependable results.

Optical Data Couplers
• Optical data couplers are designed to enable reliable wireless communication in industrial environments, such as with stock feeders, industrial trucks, automated transport systems, overhead conveyors, and docking stations. They use optical transmission instead of physical connections or radio frequency methods, eliminating issues associated with mechanical wear, RF interference, or unstable Wi-Fi signals. This ensures consistent and maintenance-free data exchange. Available in various operating ranges and data transfer speeds, optical data couplers provide flexible solutions tailored to different industrial requirements, improving efficiency and reliability in automated material handling and logistics systems.

Light Grids
• Light grids are designed for monitoring larger detection areas, making them ideal for applications where wide coverage is required. Compared to using multiple individual photoelectric sensors, light grids are easier to install, mount, and align, saving time and effort. They are widely used in material handling systems to measure pallet dimensions such as width, height, and profile. Additionally, they can detect objects regardless of position, control overlap on large conveyed items, and enhance safety by monitoring areas like elevator doors. Their efficiency and flexibility make them a practical solution for complex industrial automation tasks.

Safety Thru-Beam Sensors
• Safety thru-beam sensors provide a simple and cost-effective solution for protecting hazardous areas in industrial environments. These sensors use a transmitter and receiver placed opposite each other to detect interruptions in a light beam, ensuring reliable presence detection. When integrated with a safety control unit, they form a complete photoelectric safety system. This setup can meet international safety standards, such as Type 2 or Type 4 classifications according to EN ISO IEC 61496. As a result, safety thru-beam sensors are widely used to enhance machine safety, prevent accidents, and ensure compliance with industrial safety regulations.

Safety Edges
• Safety edges are protective devices used in areas where moving parts or edges present potential hazards. They consist of a flexible rubber profile that deforms when pressure is applied. Once activated, the safety edge sends a signal through a connected control interface unit to immediately stop machine movement, preventing accidents or injuries. These pressure-sensitive devices are highly effective for safeguarding pinch points, doors, and automated systems. Designed to meet strict safety standards, safety edges can achieve up to Performance Level “e” according to EN ISO 13849-1, ensuring maximum reliability and protection in industrial safety applications.

Safety Control Units
• Safety control units are designed to connect and manage various machine safety components within industrial systems. With a modular design, systems like SafeBox offer high flexibility, allowing users to configure the setup according to specific application requirements. Multiple safety devices can be integrated into a single control interface, simplifying system architecture and improving efficiency. These control units are compatible with a wide range of safety equipment, including photoelectric safety sensors, mechanical protective devices, and safety switches. As a result, they play a crucial role in ensuring reliable machine operation, enhancing safety performance, and supporting compliance with industrial safety standards.
