Weidmüller is a leading international provider of solutions for electrical connectivity,transmission and conditioning of power, signal and data in industrial environments.The company with headquarters in Detmold/Germany develops, produces and sellsproducts in the field of electrical connectivity and electronics all over the world.
The surfaces are usually given
a coating tin, which creates an
extremely good, “malleable” contact
with low contact resistance. Experience gained from
storage outdoor test racks different
locations (industrial, marine, tropical and
normal atmospheres) has been incor-
porated into the design the surface
protection. The
surface protection conforms the
highest standards, matched the
special requirements the connection

from ensuring consistently good electrical
