Change-over contact

Description

Features

The series S4440 mechanical vacuum switch is designed
for applications where the requirement is for the highest
accuracy and loadability. The setpoint adjustment remains
stable even for several years.
The switches convert pneumatic signals into electrical
signals. Depending on the type of connection, they can be
used as a NO, NC or CO contact without any problems.
Fitted DIN connectors make installation a quick and easy
task. The series S4440 vacuum switch from von tecsis is
used primarily in rough vacuums (technical vacuums). Here
a vacuum is understood to mean the pressure of a gas/fluid
that is lower than the surrounding pressure.
