Siemens 3RG6143-3MM00 Ultrasonic Sonar Sensor

Siemens 3RG6143-3MM00 Ultrasonic Sonar Sensor is a Set 3 Sonar ultrasonic distance sensor for non-contact object and level detection in industrial automation. It operates from a 20–30 V DC supply. Its measurement range spans roughly 100 mm to 2000 mm, enabling detection of objects at short to medium distances. The unit is often described in Pepperl+Fuchs labeling as 3RG6143-3MM00-PF, indicating it is the PF-branded variant of the same Siemens Set 3 Sonar sensor. Designed for distance and level measurement in industrial environments, the Set 3 Sonar family provides non-contact sensing in automation tasks such as presence detection, material level monitoring, and process control.
