Position Switches
Precision single limit switches
Design
The die-cast aluminum housings for the EUCHNER precision single
limit switches have been proven in even the harshest conditions
with their high strength and resistance to corrosion.
They do not require a protective paint finish, but can be painted
at any time without prior treatment.
Depending on the design, the hardened plungers made of
stainless steel run precisely in either the anodic oxidized guide
bore in the housing or in a sintered bronze sleeve.
These maintenance-free sliding elements make a key contribution
to the reliability and correct operation of the switches. Even
beyond the guaranteed mechanical life.
Exterior diaphragm
To provide protection against resinous cooling lubricants and
against the penetration of very small particles, e. g. saw dust,
graphite and glass dust, a series with an exterior diaphragm is
available.
The exterior diaphragm provides additional sealing of the plunger
outside the housing.
The plunger guides in the housing are thus reliably protected
from the penetration of the cooling lubricant. Plunger sticking is
prevented and the replacement of the switch or plunger is
unnecessary. For technical data on this series see page 27.
Seals
EUCHNER uses the high-quality and proven acrylonitrile-butadiene
rubber (NBR) for all seals and sealed areas. This material is
resistant to oils, greases, fuels, hydraulic fluids and most known
cooling lubricants. Moreover, NBR possesses high mechanical
rigidity over a wide temperature range and so it is perfectly
suitable for the highly stressed diaphragm seal, which separa-
tes the plunger compartment and the interior of the switch.
The material of the diaphragm seal is a key criterion for the
quality, mechanical life and precision of the EUCHNER precision
multiple limit switches. The same material is used for the cover
seal and the cable entry.
