SICK WTB2S-2E1330 Compact Photoelectric Sensor with BGS

The Applications

1. Micro-Component Detection in Electronics Assembly

In electronics production, machines must reliably detect very small components such as chips, pins, or connectors to avoid assembly defects. This sensor is effective in such environments because its focused light spot can clearly distinguish tiny parts from surrounding structures. The background suppression function prevents reflective circuit boards or metal tooling from triggering false signals. Its fast response supports rapid conveyor movement, while the compact housing allows installation inside densely packed assembly stations. As a result, manufacturers benefit from improved detection accuracy, fewer missed components, and more stable high-speed production.

2. Part Presence Verification in High-Speed Packaging Lines

Automated packaging systems often require confirmation that small items such as inserts, labels, or sachets are present before sealing. This sensor performs reliably at close distances and maintains consistent switching even when packaging materials vary in color or surface finish. Background suppression ensures conveyor belts or rollers behind the product do not affect detection. Its quick response time allows seamless operation on fast-moving lines, while the fixed optical setup minimizes setup errors. This helps reduce packaging mistakes, product waste, and unplanned line stoppages.

3. Edge and Position Detection in Precision Machinery

Precision machinery relies on accurate position feedback to control timing and movement. This sensor is suitable for detecting edges, slots, or thin mechanical parts where accuracy is critical. The narrow light beam enables consistent switching points, even when metal frames or guides are close to the sensing area. Its small size supports integration into compact mechanisms such as linear actuators or pick-and-place units. By delivering reliable position signals, it helps improve motion accuracy, reduce mechanical stress, and support smoother machine operation.

4. Small Object Detection in Laboratory and Medical Automation

Laboratory and medical automation systems frequently handle delicate items such as cartridges, vials, or test strips that must be detected without physical contact. This sensor provides stable, repeatable detection while avoiding interference from nearby holders or guide rails. Background suppression improves reliability in compact instrument designs, and the sealed housing supports continuous operation in controlled environments. Accurate detection helps maintain consistent workflows, reduces handling errors, and supports dependable automated processes in analytical and diagnostic equipment.
