1. High-Speed Electronic Component Presence Detection
In automated PCB assembly lines, tiny electronic surface-mount devices (SMDs) or IC chips must be detected on conveyor belts prior to pick-and-place operations [2.1.4]. The GTB2S-E1451's miniature form factor (7.7mm width) fits easily into tight machine spaces, while its small Ø 3.5 mm PinPoint LED spot enables precise targeting of small components.
Problem SolvedTraditional sensors fail because different component colors or shiny PCB background surfaces cause false triggers. The background suppression (BGS) of this sensor ignores background reflections from the PCB, ensuring only the target component is detected.

2. Compact Packaging Line Bottle Cap Detection
In compact cosmetic or pharmaceutical packaging machines, the sensor is used to verify the presence of dark or opaque caps on bottles. Since it is dark-switching, it outputs a signal when the light beam is interrupted, indicating a capped bottle is in position.
Problem SolvedSpace on bottle filling starwheels is extremely limited, preventing the use of standard-sized sensors. The sub-centimeter width (7.7mm) and 2m integrated cable of this sensor allow mounting directly inside the narrow starwheel pocket. IP67 rating protects it against liquid splashes during cleaning.

3. Automatic Tray Sorting and Positioning
In automated warehousing or laboratory sample-sorting systems, plastic trays of varying reflectivity are sorted. The sensor detects the leading edge of trays moving at speeds up to 1.5 m/s, triggering sorting gates.
Problem SolvedVarying tray colors (from white to black) usually cause fluctuating detection ranges with standard diffuse sensors. The GTB2S-E1451's background suppression and 3-turn potentiometer ensure a stable detection range from 2mm to 120mm, maintaining high accuracy irrespective of target color or material reflectivity.
