IMPORTANT
We recommend to use a prefuse of the maximum current rating from the table above according to
the load switched.
We recommend gold plated contacts for all intrinsically safe and other applications with low
voltage/power.
Operating life time
Normal expected service life (expressed in the number of cycles over the full adjustment range) is
appr. 0.5...1 million for the pressure switch.
Switch sensor life may also be effected negatively by:
Media not compatible with the wetted materials.
Too high switch cycling speed or more than 30 cycles per minute.
System cycling pressure exceeding the top of the adjustable range.
The proof pressure must never be exceeded, otherwise the switch may be damaged. Careful
selection of the pressure range can have a positive effect on the service life of the switch.

Page 2: Intended Applications
Intended Applications IMPORTANT The pressure switches are specifically applied for monitoring and controlling of operations using maximum and minimum pressures. A micro switch triggers an electrical signal when minimum or Refers to important information essential to the user. maximum pressure are reached. DANGER Disposal The equipment must be disposed of correctly in accordance with the local regulations for... -
Page 3: Transport/Storage
Transport/Storage Contact Protection The micro switches used are normally suitable for both direct and alternating current operation. CAUTION Inductive, capacitive and lamp loads may, however, considerably reduce the life expectancy of a micro switch and, under extreme circumstances, even damage the contacts. Severe shock and vibrations should be avoided during transport. - Page 4 In pressure switches, a displacement of the pressure sensing element occurs with a change in pressure. Following the displacement of the pressure sensing element operates a microswitch. Precise adjustment of set point to actuate on decreasing pressure Upon delivery of the product, the set points are likely to be found in the middle of the adjustable ...
