Vishay has introduced a new concept in panel mounted potentiometers. The innovative design intended for military, (professional) audio and industrial applications consists of a knob driving and incorporating a cermet potentiometer and a switch. Only the mounting hardware and terminals are situated on the back side of the panel reducing to a minimum the required clearance.
The new potentiometer with a value ranging from 22 Ω to 10 MΩ is available as a cermet device for military applications (P16S) or with a conductive plastic element for audio applications (PA16S). The cermet version can dissipate 1 W, the plastic version 0.5 W. With its hermetically sealed case (IP67) the potentiometers require a mounting clearance of only 15 mm. The knobs can be plastic or metal, custom knobs are available on request. [via]
