General
The electro-hydraulic pressure switch provides an electric
signal when sensed pressure rises above or falls below
the selected setting.
Function
The spring loaded piston is hydraulically dampened. The
pressure difference cannot be set, but is given by the
switch hysteresis.
The required operating pressure is adjusted by a set-
screw. Unauthorised adjustments may be prevented by
fitting a cylinder lock. The electric element is a micro
switch with snap-action contact. Three terminals permit
application as "On", "Off" or "Changeover" switch.
The electrical connection is made with a 3-pole plug-in
connector to DIN 43650 with ground.
Features
• Flange mounting
• Actuating pressure adjustable
• Can be used as opener or closer
• Cylinder lock possible
Technical data
Note
For inductive DC loads a spark discharger should be used
to increase service life.
