Compact SICK GTB2F-N1131 photoelectric sensor with precise background suppression, fast response, and reliable detection for industrial automation.
The SICK GTB2F-N1131 Photoelectric Sensor is a compact sensing solution built for precision detection in confined industrial spaces. Using visible red light with background suppression, it identifies small objects up to 0.1 mm within a 30 mm sensing range. Its flat and durable VISTAL® housing (14 × 24 × 3.5 mm) enables flexible mounting on machinery or conveyor systems. Designed for stability and reliability, it operates on a 10–30 V DC supply and responds in under 0.625 ms, ensuring fast and accurate detection even in rapid production environments. With an IP67 rating, it withstands dust, vibration, and moisture for consistent long-term performance.
The GTB2F-N1131 enhances automation efficiency by offering precise object detection regardless of surface reflectivity or color. Its PinPoint LED emitter creates a fine red light spot that ensures accurate positioning and consistent operation, even in tight setups. The built-in NPN switching output connects easily to control systems, while internal protections guard against reverse polarity, short circuits, and overloads. Lightweight and easy to install, this sensor improves product quality control, minimizes downtime, and ensures repeatable results in high-speed packaging, electronic assembly, and component placement applications.
The SICK GTB2F-N1131 stands out for its ability to deliver micron-level detection in ultra-tight spaces. Its slim, rugged body and advanced background suppression make it ideal for precision assembly and electronic production lines where accuracy and stability are critical. It’s a compact powerhouse built for environments that demand reliability without compromise.
The GTB2F-N1131 solves the challenge of false triggering and unstable detection in reflective, complex, or small-object environments. Traditional sensors struggle with changing backgrounds or shiny surfaces, but this model’s PinPoint LED and intelligent optical design ensure consistent, accurate detection—reducing downtime, improving process quality, and maintaining efficiency in high-speed automation systems.

1. PCB Component Alignment in Electronics Assembly
In printed circuit board production, precise component positioning is essential for flawless assembly. The SICK GTB2F-N1131 detects tiny parts and edges with its fine 0.1 mm resolution, ensuring accurate placement before soldering. Its background suppression minimizes false detection from reflective board surfaces or metallic pads. Compact and fast-reacting, the sensor integrates easily into robotic arms or pick-and-place tools, improving assembly precision, reducing scrap, and maintaining consistent product quality at high production speeds.
2. Packaging Line Bottle and Cap Verification
In beverage and cosmetic packaging, missing or tilted caps can cause costly production delays. The GTB2F-N1131 identifies cap presence or misalignment instantly using its PinPoint red LED. Its short sensing range focuses detection only where needed, avoiding false signals from conveyors or shiny bottles. The sensor’s rapid 0.625 ms response supports continuous inspection without slowing production, helping manufacturers maintain packaging integrity and minimize downtime.
3. Precision Detection in Robotic Grippers
For automated handling systems, ensuring a part is correctly gripped is vital for accuracy. The GTB2F-N1131 confirms the presence of small objects before robotic movement begins, preventing empty or double picks. Its ultra-slim 3.5 mm housing fits seamlessly inside compact grippers, while NPN output signals provide instant feedback to the robot controller. This sensor enables smoother handling cycles, reduces part slippage, and improves operational reliability in precision assembly lines.
4. Edge and Label Detection in Printing Machines
High-speed printing and labeling require reliable edge detection for accurate registration. The GTB2F-N1131 distinguishes slight contrast differences between paper edges, film layers, or adhesive labels using a focused red light spot. Its 800 Hz switching frequency ensures consistent detection at rapid speeds, maintaining proper label alignment and minimizing waste. With excellent stability against vibration and dust, the sensor keeps labeling operations efficient, reducing production errors and ensuring consistent print accuracy.
