The DataSensing QM Series is a line of high‑performance miniature cubic photoelectric sensors designed for versatile object detection tasks in industrial automation. Featuring a robust compact housing with IP67 protection, the series offers a broad range of optical detection modes including diffuse proximity at short, medium, and long distances, polarized retro‑reflective sensing, through‑beam emitter/receiver pairs with very long range, and background suppression models with adjustable sensitivity. These sensors operate with selectable PNP or NPN output configuration and LO/DO output states, and are available with M8 connectors, fixed cables, or M8‑M12 pig‑tail connections, allowing easy integration into conveyor systems, packaging lines, inspection stations, and automated machinery.
Designed for demanding industrial environments, QM Series sensors combine high switching frequencies (up to ≈2 kHz) with repeatable detection and strong electrical protections such as reverse polarity and short‑circuit immunity. Typical variants include diffuse sensors with ranges from ≈100 mm to ≈1 000 mm, polarized retro‑reflective models detecting up to several meters, background suppression for consistent target detection regardless of background, and remote emitter/receiver pairs for long‑range object sensing up to about 20 – 30 m. The series accommodates visible red LED or infrared emission types to suit different installation and target conditions.
