HLS-440P − Handling Instructions
Due to the fact that the sensor element consists of a silicon chip
facing the surrounding the following precautions have to be
taken into account:
During storage and handling avoid:
• Humidity (condensing conditions)
• Dropping (sensor must be replaced if dropped)
• Dust (especially if cap is removed)
• Mechanical impact (especially the entrance membrane)
• Electromagnetic radiation (RF fields, high magnetic fields)
In case of storage and transport it is recommended to keep the
sensor within its original packaging (plastic cap and ESD
protected bubble bag). The disassembly of any parts is not
allowed, except for the removal of the plastic cap directly before
final assembly.
