The RU50 Eco series has been expanded to include analog variants. The sensors have a plastic threaded barrel made of durable liquid crystal polymer and a sensing range of 500 mm. They use sonic transducer technology for object detection. Teachable switching points and sensing distance ensure users can configure the sensors to detect objects between the sensor and the reference point. Even bad lighting conditions and glossy or reflective surfaces have no influence on the sensor. PNP and NPN switching versions as well as analog 4-20 mA and 0-10 V are available. Output options include an M12 connector or a 2-m cable.
