The Sick WL12G-3P2572 Photoelectric Sensor is engineered with a retro-reflective sensing principle and advanced autocollimation technology, making it ideal for detecting transparent or irregularly shaped objects with high precision. It operates with a PinPoint LED light source emitting visible red light at 660 nm wavelength, and produces a 25 mm diameter light spot at 1.5 meters. This optical setup ensures stable performance even in challenging applications like detecting clear bottles, films, or glass surfaces on conveyor systems.
Operating on a 10 V to 30 V DC supply voltage, the sensor maintains a low current consumption of 40 mA, making it highly efficient. It supports light/dark switching and provides a PNP digital output with a fast response time of β€ 333 Β΅s and a switching frequency of 1,500 Hz. These specifications make it highly reliable in high-speed automation lines. The robust metal housing (15.6 mm Γ 48.5 mm Γ 42 mm) and IP66/IP67 protection ensure long-lasting performance in harsh factory environments. Its M12, 5-pin male connector allows secure integration into PLC systems. Trusted in sectors like packaging, pharmaceuticals, and electronics, the WL12G-3P2572 helps industries achieve consistent sensing with minimal maintenance.
