The SICK GRTB18-P2406S07 is a Type 4, IEC 61496-1/-2 compliant Safety Light Curtain from the high-performance GRTB series. It is engineered to provide the highest level of personnel protection (Category 4, PL e according to ISO 13849-1) around hazardous machinery. This system creates an invisible vertical curtain of infrared light beams; when any beam is interrupted, it sends a stop signal to the machine's safety relay or controller to initiate an immediate shutdown, preventing injury.

The SICK WT9-2P430 is a compact, self-contained through-beam photoelectric sensor from the robust WT9 series. It integrates both the transmitter (emitter) and receiver into a single, unified housing, creating a precise "optical fork" or "U-channel" for detection. Objects are detected the moment they break the infrared light beam traveling directly between the built-in emitter and receiver. This design offers the high reliability of a through-beam system in an extremely compact and easy-to-install format.

The SICK WE100-2P1432 is an advanced multifunctional photoelectric sensor from the feature-rich WE100 series. It is engineered for highly flexible and precise object detection in complex industrial applications. Its standout feature is a teach-in functionality, allowing for quick and easy configuration of its operating mode and sensitivity directly on the device without the need for external tools or complex potentiometer adjustment

The SICK WL11-B560 is a retro-reflective photoelectric sensor from the versatile WL11 series. It is designed for reliable object detection at medium to long ranges. This sensor operates by emitting a light beam (invisible infrared in this case) towards a dedicated reflector. The reflector bounces the beam directly back to the sensor's receiver. An object is detected when it breaks this beam path, preventing the light from returning to the sensor.

The SICK GS10-D4311 is a Safety Light Curtain (also known as a Type 2 ESPE) belonging to the compact GS10 series. It is designed to safeguard personnel by creating an invisible protective field around hazardous machinery. When this light beam is interrupted by an object or person, the device sends a stop signal to the machine's control system (e.g., a safety relay), halting operation and preventing injury.

The SICK WT24-2B420 is a compact, through-beam photoelectric sensor from the robust WT24 series. Characterized by its high power and exceptional reliability, this sensor system consists of two separate units: a transmitter (emitter) and a receiver. It generates a continuous beam of infrared light; an object is detected when it interrupts this beam path between the two components. This design makes it one of the most powerful and dependable sensing principles for long-range and challenging industrial environments.

The SICK WE36-B430 is a compact, self-contained photoelectric sensor from the high-performance WE36 series. It utilizes Background Suppression (BGS) technology, making it an exceptionally reliable solution for precise object detection within a defined range, while effectively ignoring any backgrounds or objects beyond that point. Its robust design, ease of use, and visible red light beam make it a versatile choice for a vast array of industrial automation applications.

The WL100L-F1131S04 is a miniature retro-reflective photoelectric sensor featuring a dual-lens design that enables reliable detection even at close distances. It utilizes a visible red Class 1 laser, offers light/dark switching, and includes adjustable sensitivity—all within a compact and rugged housing ideal for precision industrial detection.

The WFL50-40B416 is a compact fork-style photoelectric sensor that uses a red laser and fork optics (50 mm width × 42 mm depth) to detect very fine objects (down to 0.05 mm). Featuring intuitive plus/minus button sensitivity adjustment and PNP/NPN light/dark selectable output, it combines high-speed performance with a rugged aluminum housing (IP65) for reliable detection in industrial settings.

The WL9-2P131 is a compact retro-reflective photoelectric sensor with a visible red LED and polarization filter. It offers precise detection up to 3 m (max. 4 m with reflector), uses a slim rectangular housing, and features a teach-in button, PNP light/dark switching, and IP69K protection—ideal for tight and harsh industrial environments.
