The specified pressure applies per cycle and occasionally. OsiSense XMLA pressure switches. Schneider Electric XMLA pressure switches for control circuits are used to monitor the pressure of hydraulic oils, fresh water, seawater, air, steam, corrosive liquids, or viscous products. The XMLA pressure and vacuum switches have a fixed differential and are designed to detect a single threshold. Fixed differential, external pressure adjustment window available, switching contacts: 1 normally closed and 1 normally open. Temperature range: –25 to +70 °C. Protection class: IP65 with plug connector, IP66 with terminal connections. Operating rate: up to 120 switching cycles/min for membrane and 60/min for piston. Media connection: 1/4 inch NPT. Conduit connection: 1/2 inch NPT.
