Schneider Electric XMLBS35R2S11 Pressure Switch

Schneider Electric XMLBS35R2S11 is an industrial pressure switch designed to regulate fluid and air pressure in hydraulic power units, air compressors, pumping stations, and process equipment. Part of the OsiSense XM series, it uses a diaphragm actuator, a 1 C/O contact configuration, and a G 1/4 female ISO 228 fluid connection, with IP66 protection and a zinc-alloy enclosure for demanding environments. Key specifications include a 0.35 bar pressure rating, a rising switching range of 0.042–0.33 bar, a falling switching range of 0.009–0.272 bar, and a maximum permissible pressure of 30 bar, operating from -25 °C to 70 °C. Common replacements include XMLA004A2S11 and XMLB004A2S11, reflecting its role in retrofit projects and ongoing pressure-control maintenance.
