Miniature 5/8"

(16mm) Diameter

Composition

Variable Resistors

• Miniature 5/8" (16mm) size

• Versatile mounting styles:

– bushing

– twist tab

– bend tab

– snap-in PC bracket

– solder lug or PC terminals

(shaft parallel or perpendicular to the panel)

• 100 Ω to 5 Meg Ω resistance range

• Molded or metal shafts

• SPST power switches

• Single, tandem, or concentric units

• Panel seal

• Rear extended shaft

Standard Position: Left side supplied unless otherwise

specified.

Other Positions: Available with lug right side,

without lugs, or with lugs both

Metal

left and right sides.

Lengths: Minimum .1±5" (3.±mm) beyond bushing;

special lengths as required.

Trims:

Plain round screwdriver slotted, flatted,

knurled. Other trims available

upon request.

Water Seal Construction

Controls are also available to prevent water

from entering the control through either the

O.D. of shaft and/or the bushing.

Molded

Flatted and knurled with screwdriver slot available

in many lengths and diameters.
