EXTREME Product Line for ASi

The EXTREME Product Line modules from Bihl+Wiedemann are built for use under extreme conditions. The combination of IP67 protection rating and the ASi standard enables reliable and efficient communication between machines.

100% protection against moisture

Machines and communication devices which are installed in an outdoor area, can be subjected to strong temperature fluctuations and high humidity. Regular variations in temperature between day and night cause dew formation when the air becomes saturated.


  • Waterproof plastic housing
  • Protects up to 100% relative humidity
  • The coated circuit board provides the highest resistance to condensation
  • Optimal protection against ice formation inside the module

Highest resistance to salt spray

The use of machines at sea or in coastal areas puts extremely high demands on the electronics. The aggressive properties of sodium chloride cause irreparable damage (corrosion) to machines and control elements.

  • Coated circuit boards provide assured functionality even under continuous contact with salt spray
  • Products are tested to EN 60068-2-52 Severity Level 3

High corrosion resistance

The risk for corrosion damage to electronic products and components is always high when automation equipment is exposed to chemically reactive environments. Simulations in the environmental chamber of a testing laboratory verify the resistance of Bihl+Wiedemann products in contact with an aggressive gas mixture.
