Fully Sealed Container Cermet Potentiometer
Military and Professional Grade
SPECIAL FEATURES
COMMAND SHAFT
Length is measured from the mounting surface to the free
end of the shaft. The screwdriver slot is aligned with the
wiper within ± 10°. Special shafts are available, in
accordance to drawings supplied by customers. We
recommend that customers should not machine shafts, in
order to avoid damage. Bending or torsion of terminals
should also be avoided.
PANEL SEALING: PE30P
The panel sealing device consists of a ring located in a slot
on the potentiometer face. Sealing is obtained by tightening
the ring against the panel when mounting the potentiometer.
LINEARITY
The typical linearity of linear variation law potentiometers is
± 5 %. Guaranteed linearity on request. Consult VISHAY.
SHAFT LOCKING: DBAN
The shaft locking device consists of a tapered nut tightening
a slotted notched washer against both bushing and shaft.
DBAN tightening torque is 200 Ncm, shaft locking torque
being 30 Ncm.
DBAN is also available with all special types.
This device is normally supplied in a separate bag. Can be
pre-mounted on request.
LOCATING PEG: LPRP
Location is obtained by fitting a special washer in 2 holes
drilled at 180° in the potentiometer face.
