Betatronix offers various types of elements to meet any customer requirement

Conductive Plastic


Cermet combines ceramic with precious metals to created a resistive material.

Stable resistance over time and temperature change

Low Noise

Good Frequency response

Temperature coefficient better than conductive plastic but worse than wirewound

Higher surface roughness than conductive plastic

Modern carbon film element made with plastic resin and carbon powder.

Most economical option

Better noise performance that cermet

High surface smoothness, longer life than cermet

Infinite resolution

Worse moisture resistance, temperature coefficient, power dissipation, and wiper current capacity than cermet

Stable over time and temperature change

Low static noise

High Power

Long life

Narrow range of resistance

Co-Molded Plastic

Mirror-like finish with no delamination
