149 Series 1/2" (12.7mm) Cermet Potentiometers

Vishay / Spectrol 149 Series 1/2" (12.7mm) Cermet Potentiometers offer a high rotational life of 50,000 cycles and a low temperature coefficient of ±150ppm/°C in an industrial-grade design. These devices are available with one or more detents, or without a detent, and the tapers include linear, logarithmic, and reverse-log. Additional features include up to three sections of PC support plates and limited clearance required behind the panel. Vishay / Spectrol 149 Series 1/2" (12.7mm) Cermet Potentiometers feature dust-proof and lead-free construction and RoHS compliance. This product line is ideal for industrial applications, including panel adjustments, hot-air blowers, and variable-frequency drives.
