SPECIAL FEATURES

PANEL SEALING

Potentiometers P13T and P13V can be fitted with a device

providing sealing between the threaded bushing and the

front panel. Their designation is P13TP and P13VP

respectively or with a locating peg P13TPE and P13VPE.

SHAFT

Shaft lengths are measured from the mounting surface to the

free end of the potentiometer. Special shafts are available,

provided customer supplies a drawing.

The shaft slot is aligned to the wiper within ± 10°.

SHAFT LOCKING

On potentiometers equipped with a 3 mm Ø shaft, shaft

locking can be obtained:

- either by a taper nut tightening a slotted bushing. Ask for

P13H type. These devices are normally equipped with an L

type shaft (12.5 mm with a slot),

- or by a tightening nut locked by a screw. Ask for ES1 type.

On potentiometers equipped with a Ø 6 mm shaft, locking

can be obtained by a taper nut applying pressure on a

slotted notched washer. This device is supplied in a box as

an accessory. Ask for DBAN.

These devices are ordered separately. Please consult

VISHAY SFERNICE.
