• Pressure switches for use with water in autoclave systems
• The switch ensures automatically the starting and stopping of the electric pump according to the set pressure values
• Electric contacts: normally closed and made of brass alloy with Ag-Ni surfacing
• Terminals with M4 screws and 8x8 mm pressure dice
• NBR rubber membrane with textile insert (food grade for PM/5 - PM/6 - PT/5)
• ¼" F hydraulic connection made of galvanized steel
• Standard protection degree IP 44
• Max ambient temperature: 55°C
• Tear resistant cable clamps
APPLICATIONS: Pressure switches for firefighting systems, Pressure switches for water pumps
