SICK WTB2S-2F3130 compact photoelectric sensor with background suppression for precise small-object detection in tight industrial automation spaces.
SICK WTB2S-2F3130 photoelectric sensor with background suppression is a compact, high-precision solution developed for accurate detection of very small objects at short distances. It addresses common automation challenges such as unreliable sensing caused by background reflections or limited installation space. Designed within the W2 sensor family, this model combines a miniature housing with precise optical performance, making it suitable for tightly packed machinery. Its visible red PinPoint LED enables stable detection within a controlled sensing range, ensuring consistent results even in applications where space, precision, and reliability are critical.
The SICK WTB2S-2F3130 delivers dependable object detection in applications where conventional sensors often generate false signals. Its background suppression technology allows the sensor to distinguish targets from nearby surfaces, improving process stability and reducing unplanned stoppages. The fast switching capability supports high-speed operations, while the clearly defined light spot simplifies setup and alignment during installation. Built with a rugged housing and sealed to industrial standards, the sensor performs reliably across varying temperatures, making it well suited for electronics assembly, miniature part handling, and compact automation systems.
Why SICK WTB2S-2F3130?
The SICK WTB2S-2F3130 is chosen when precision, consistency, and space efficiency matter most. Its ultra-compact design fits easily into tight mechanical layouts, while the focused PinPoint LED delivers highly repeatable detection of small or low-contrast objects. By combining stable background suppression with fast response performance, this sensor helps manufacturers achieve smoother operation, higher throughput, and reduced adjustment effort across demanding automation tasks.
What problem does it solve?
The SICK WTB2S-2F3130 eliminates unreliable sensing caused by reflections, color variations, and nearby background surfaces. In applications handling tiny components or closely spaced parts, standard sensors often misread targets or trigger inconsistently. This model precisely separates the object from its surroundings, ensuring accurate switching at close range and preventing false signals that lead to production errors, stoppages, or quality issues.

In modern electronics assembly, detecting very small components such as connectors, pins, or molded plastic parts requires high accuracy within extremely limited space. The SICK WTB2S-2F3130 is well suited for this task because its background suppression allows it to detect only the target object while ignoring fixtures or tooling located just behind it. The tightly focused light spot improves consistency when components differ slightly in color or surface finish. Its fast switching behavior supports rapid assembly cycles, helping reduce missed detections, rework, and stoppages in high-density production cells.
Miniature conveyor systems used in sorting, feeding, or packaging often place sensors very close to guide rails and mechanical supports. In such layouts, standard sensors may falsely detect surrounding structures. The SICK WTB2S-2F3130 overcomes this by limiting detection to a defined short range, ensuring only the passing item is recognized. This enables stable part presence monitoring even at high conveyor speeds. The compact housing simplifies mechanical integration, allowing system designers to maintain clean layouts without compromising detection reliability or system responsiveness.
Precision assembly processes rely on exact confirmation of component position before the next operation begins. The SICK WTB2S-2F3130 provides dependable feedback by detecting small parts at close distances while remaining insensitive to nearby machine elements. Its background suppression reduces false signals caused by reflections from metal frames or tooling. The visible red sensing point helps technicians align the sensor accurately during setup, improving repeatability. This results in more consistent assembly quality, reduced adjustment time, and lower risk of downstream process errors.
Automated packaging lines handling small or thin products often struggle with unreliable detection caused by reflective packaging materials or tight mechanical spacing. The SICK WTB2S-2F3130 ensures stable product detection by clearly separating the item from its background within a short sensing distance. Its fast response supports continuous, high-throughput operation, enabling accurate counting, positioning, or triggering of packaging actions. The robust, sealed construction allows long-term use in industrial environments, helping manufacturers minimize packaging faults and maintain smooth, uninterrupted production flow.
