The SICK G2 photoelectric sensor is a compact, reliable proximity sensor designed for precise object detection in industrial environments. Based on background suppression technology, it reliably detects objects within a defined sensing range by distinguishing target objects from the surrounding background. With its visible red PinPoint LED light source and small form factor (7.7 mm x 27.5 mm x 13.5 mm), the G2 offers efficient integration into tight spaces. Ideal for applications requiring fast response times and stable performance, this sensor ensures consistent detection accuracy under varying conditions using a simple PNP switching output. Its robust design and proven reliability make it suitable for use in automated production lines where dependable sensing is critical.
The G2 employs background suppression technology to detect objects with high precision, effectively filtering out ambient background signals. It uses a PinPoint LED light source emitting visible red light, creating a focused beam that enhances detection accuracy and reduces false triggers. The sensor operates within a sensing range of 25 mm to 90 mm when detecting objects with 90% remission (based on standard white, DIN 5033). With a light spot size of Ø 3.5 mm at 50 mm distance, the G2 delivers consistent beam focus for reliable object identification. The sensor’s response time is less than 0.6 ms under resistive load conditions, ensuring fast and accurate switching actions. Its average service life exceeds 100,000 hours when operated at +25 °C, contributing to long-term operational stability.
The SICK G2 photoelectric sensor features a maximum sensing range of 2 mm to 120 mm (based on 90% remission). It operates with a supply voltage of 10 V DC to 30 V DC, maintaining stability within ripple limits of less than 5 V pp. The current consumption is consistently 20 mA, and the maximum output current is ≤ 50 mA. The sensor provides a PNP switching output in light-switching mode with a switching frequency up to 800 Hz. It is protected against overcurrent and short-circuit conditions at its outputs (D), ensuring safe operation under fault conditions. The device includes reverse-polarity protection for A = V S connections, enhancing safety during installation.
The G2 sensor connects via a 3-pin M8 cable with a 200 mm length, featuring a plastic PVC cable construction with a diameter of Ø 3 mm. This standard cable configuration simplifies integration into existing automation systems without requiring custom wiring. The PNP switching output allows compatibility with most industrial control systems and PLCs. The sensor is designed for direct mounting in applications where space efficiency and reliable signal transmission are essential. Its compact rectangular housing design supports easy installation in tight mechanical layouts. The cable’s standard length ensures flexibility during setup while maintaining signal integrity.
The G2 sensor operates reliably within a supply voltage range of 10 V DC to 30 V DC, with performance maintained as long as the voltage does not fall below or exceed specified tolerances. It is designed for use in environments where ambient temperatures are typical industrial conditions and where short-circuit protection is required—limiting maximum current to 8 A when operated in a short-circuit protected network. The sensor’s robust construction ensures stable operation under standard environmental conditions, with no specific humidity or temperature ratings provided. However, its long-term reliability at +25 °C (100,000 h average service life) indicates suitability for continuous industrial use.
The SICK G2 is ideal for applications requiring reliable object detection in automated production processes such as packaging, assembly, and material handling. Its background suppression technology ensures accurate detection of small or irregularly shaped objects against a uniform background. The sensor’s fast response time (<0.6 ms) and high switching frequency (up to 800 Hz) make it suitable for dynamic environments where rapid cycle times are required. It is particularly effective in detecting parts with moderate reflectivity, such as plastic or metal components, within the specified sensing range of 25 mm to 90 mm. The compact size and simple cable connection support integration into automated systems where space and ease of installation are key considerations.
