Electrical Ratings Type KD1
Silver contacts
Inductive load
30 V =
3.0 A
IMPORTANT
Data only valid for application in non-explosive atmosphere.
We recommend to use a prefuse of the maximum current rating from the table above according to
the load switched.
As the lamp load is hardly relevant in the field we abstain from relating details. More information on
request.
Electrical Ratings Type KLK/KLM
Silver contacts
Inductive load
30 V =
3.0 A
IMPORTANT
Data only valid for application in non-explosive atmosphere.
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. 1 million for KLK/KD1 the pressure switches and for the KLK approx 0.5 million. This may be
extended to 2.5 million cycles for piston switches max. if only a part of the adjustment range is used
(about 20%).
Switch sensor life may also be effected negatively by:
Media not compatible with the wetted materials.
Too high switch cycling speed or more than 60 cycles per minute.
System cycling pressure exceeding the top of the adjustable range.
Too high electrical ratings
The proof pressure must never be exceeded, otherwise the switch may be damaged. Careful
selection of the pressure range ant the electrical rationgs can have a positive effect on the service
life of the switch.
