SPECIAL FEATURES
SHAFTS
Lengths are measured from the mounting surface to the free
end of shaft. Shaft slot is aligned with the wiper within ± 10°.
Special shafts are available, in accordance with drawings
supplied by customers. We recommend customers not to
machine shafts, in order to avoid damage. Bending or torsion
of terminal should be avoided.
SHAFT AND PANEL SEALING HARDWARE
The type P12T with R or M shaft can be provided with an
optional “DE” sealing hardware which ensures sealing of
both the shaft and the mounting panel. “DE” sealing
hardware can be supplied in a separate envelope.
SHAFT LOCKING
- The shaft locking bushing is available only with P12H
potentiometers. Torque applied to locking nuts should not
exceed 15 Ncm.
