Schneider Electric XMLBS35R2S11 Pressure Switch

The Schneider Electric XMLBS35R2S11 pressure switch is an electromechanical device that monitors low-pressure conditions in air and hydraulic oil systems and provides adjustable differential switching via a SPDT (1 C/O) contact. It uses a diaphragm actuator and a zinc alloy housing, with a G 1/4 female ISO 228 fluid connection and screw-clamp terminals for wiring. The unit is designed for a pressure range of 0–0.35 bar with two adjustable thresholds to regulate pumps, compressors, and automation systems in pneumatic and hydraulic circuits. Components in contact with fluids include 304L stainless steel, FPM/FKM, and steel, and the enclosure carries IP66 protection for harsh industrial environments. Electrical ratings are 3 A AC-15 at 120 V AC and 1.5 A AC-15 at 240 V AC. It is suitable for air and hydraulic oil systems requiring reliable control of low-pressure setpoints and is commonly used in compressors, hydraulic power units, pumping systems, and related industrial process equipment. Compliance includes CE, CSA, UL, CCC, BV, DNV, and GL, and it is part of the XMLB family of Schneider Electric/Telemecanique pressure switches. For retrofit or upgrade projects, common replacements include XMLBS70R2S11, XMLA004A2S11, and XMLB010A2S11.
