OPTIONS

Special Feature Command Shaft

Length is measured from the mounting surface to the free end of the shaft. The screwdriver

slot is aligned with the wiper within ± 10°. Special shafts are available, in accordance to

drawings supplied by customers. We recommend that customers should not machine tool

shafts, in order to avoid damage. Bending or torsion of terminals should also be avoided.

Panel Sealing

The panel sealing device consists of a ring located in a groove on the potentiometer face.

Sealing is obtained by tightening the ring against the panel when mounting the potentiometer.

Locating Peg

Location is obtained by fitting a special washer on the mounting face of the potentiometer.
