Sealed Construction
FEATURES
• Process seal provides protection against conta-
minants (flux, solvents, etc.) during production.
• Designed for flow and reflow soldering.
• Available in carrier and reel packaging.
CONSTRUCTION DETAILS OF 4 x 4.5 mm GKG MODELS
Model GKG __ __ __ 27 Shown
• Special “drive assembly” with
pointed spring fingers to engage rotor
upper surface contour. Spring fingers
also provide proper tension for smooth
torque and low resistance.
• Special rotor with die-formed “drive”
contour on upper surface.
• Flat-lapped and lubricated surfaces
join for reliable capacitance settings.
• Special ceramic stator insert
with metalized electrode.
• Solid one-piece housing with integrally
molded terminals and contact areas.
Central tubular column is spun-out
into a flare after assembly to maintain
built-in spring tension.
