Protection Classifications
The protection classes of Saia switches are in accordance with IEC 529 and are covered by just four codes.
IP40
Adequate protection against solids such as probing fingers and small wires>1mm. Liquids however can gain access and, unless externally protected, the switches should be mounted in dry or well-sheltered positions.
IP54
Good protection against solid foreign bodies, including dust and water splashing against the enclosure from any direction.
Switches may be used out of doors if sheltered from the worst of the elements or on factory machines subjected to normal washing down procedures.
IP65
Complete protection against solids, including dust, and against low pressure jets of water from all directions.
IP6K7
Complete protection against solids including dust and against immersion in water at a specific pressure for a specified time.
We reserve this code for switches which are factory sealed and tested.
Switches should not be immersed in any liquid.
* International IK code indicates protection against mechanical impact regarding to EN 50102.
Working Temperatures
For details of the working temperatures applicable to individual types, refer to the appropriate specification sheet. Special versions suitable for temperatures outside these ranges may be possible. Please contact us for information.
All quoted temperatures assume stable operation. They do not imply an ability to withstand excessive cycling within the range.
