December, 2008
Sensors & Controls Product Group is announcing a product update to our
Potentiometer. We have phased in a minor change to the shaft confi guration. Please reference the
attached drawing below showing the design change to the shaft and associated shaft length options.
This change affects Model PDB181 and PDB182 with knurled shaft only. The shaft material will
change from aluminum to zinc-die cast. In addition, the rear cover will be tin-plated rather than
zinc-plated to allow customers to solder to the rear cover. Two new shaft lengths will be available:
15 mm and 18 mm. There are also a few minor dimension changes to the anti-rotation lug and
terminals that do not affect fi t. Please see the Model PDB18 data sheet for detailed dimensions.
The design change was phased in the week of September 15, 2008 with date codes beginning 0838.
There are no changes to fi t or function of this product. Distribution book prices will also remain
unchanged.
