FEATURES

• Proven rugged axle design prevents electrode

shifting, maximizes stability.

• Plastic washer between adjust shaft and ceramic

rotor to absorb tuning and environmental stresses.

• Special ceramic dielectric rotor with metalized

electrode.

• Flat-lapped and lubricated surfaces join for reliable

capacity settings.

• Solid one-piece stator electrode and terminal,

recessed and integral with base. Cannot shift.

Improves stability and resistance to humidity.

• Combination spring/contact/terminal maintains

proper tension for smooth torque and low resis-

tance.

• Soldered connection between adjust shaft and rotor

electrode eliminates contact resistance problems.

• Compact form factor conserves mounting space.

• Straight line capacitance curve.

• Low cost for industrial and commercial applications.

All dimensions are in / mm. Unless otherwise specified, the tolerance on dimensions is ± 0.004 / 0.1.
