GTB2F-E1311 Product Overview
The GTB2F-E1311 belongs to SICK’s G2 photoelectric sensor series and operates on the background suppression principle, which eliminates interference from surfaces behind the target object. The integrated 455 nm blue PinPoint LED enables precise detection of small parts across various surface types, including dark or low-reflectivity materials.
With its ultra-compact form factor (14 × 24 × 3.5 mm) and NPN Dark switching output, the GTB2F-E1311 easily integrates into space-constrained installations on high-speed production lines.

GTB2F-E1311 Applications in Industry
With a compact sensing range (0–16 mm) and ability to detect objects as small as 0.1 mm, the GTB2F-E1311 is ideal for applications requiring precise small-part detection:
Electronics & Semiconductor Manufacturing:
Detects SMD components, ICs, and PCBs on assembly conveyors. The Ø 3 mm light spot ensures accurate detection of individual small parts without background interference.
Packaging & Printing Lines:
Verifies the presence of labels, seals, and packaging on high-speed lines. The 800 Hz switching frequency ensures no product is missed at high conveyor speeds.
Precision Machine Automation:
Detects part positions and verifies presence on jigs or fixtures. Response time < 0.625 ms is suitable for CNC machines and pick-and-place robots.
Pharmaceutical & Medical:
Checks tablets, syringe plungers, and bottle caps on sterile packaging lines. IP67 ensures cleanliness and moisture resistance in strict manufacturing environments.
Quality Control (QC) Inspection:
Detects surface defects, voids, or missing components before packaging. Background suppression eliminates false signals from conveyor belts or support fixtures.
AUMI has supplied the GTB2F-E1311 to electronics and packaging manufacturers in Hanoi and Ho Chi Minh City, providing on-site integration support.
