The Siemens 6DR5020-.....-.... is a SIPART PS2 smart electropneumatic positioner accepting a 4-20 mA control signal, built for Ex and non-Ex environments, double-acting, with a polycarbonate enclosure designed for pneumatic linear and part-turn actuators. It uses non-contacting (wear-free) position detection (NCS), which eliminates mechanical wear on the feedback element — a key reliability point for modulating valve service where the positioner cycles continuously.
RoHS compliance is effective since 31-12-16, and REACH Article 33 information is available on request. Export control is classified as AL: N / ECCN: N, meaning no special licensing is required for most destinations. The product group code is 4759, and the group code is R3P2 — these are Siemens internal cataloging fields that help with cross-referencing in their ordering tools.
