PANEL SEALING
Except for dia. 4 mm shaft, an O.ring is supplied with the potentiometer. This O.ring should be placed into the groove of the body and ensures the panel sealing. For dia. 4mm shaft please see note "P" in ordering information.
SHAFTS
Shaft lengths are measured from the mounting face to the free end of the shaft. Special shafts are available if the customer supplies a drawing. The shaft slot is aligned to the wiper within 10.

HARDWARE
Nuts, washer and O.ring are separately supplied (not mounted on the potentiometer), in a small bag placed in the packaging.
LOCATING PEG
Except for dia. 4 mm shaft, the potentiometers are delivered with 2 opposite locating pegs orientated at 45. These 2 pegs can be easily broken-off by the customer. On request, the orientation of the pegs can be at 30 instead of 45. Order Designation : PRV6 L (see ordering information).
PACKAGING
Carton box of 50, code: BO50
MARKING
VISHAY trademark, series, style, ohmic value (in , k or M), tolerance in %, taper code, manufacturing date (4 digits : 2 for year, 2 for week), terminal 1.

"LC" OPTION LOW CURRENT
For sensitive applications, when the current going through the wiper of the potentiometer is very low (less than 1 Amp) or when the climatic conditions of use are tightened up, we recommend to use the Low Current (LC) option of the PRV6 and PARV6 series. The general characteristics of this model are identical with the standard PRV6/PARV6 characteristics but it gives exceptional results in matter of stability when used in extreme climatic conditions and/or current close to O Amp.
