Panel Potentiometers Feature 5000-VRMS Dielectric Strength
Vishay Intertechnology has announced two compact panel potentiometers with high dielectric strength of 5000 VRMS, cermet and conductive plastic elements, and a wide variety of modules and terminal styles.
WithThe versatile panel potentiometers offer a wide range of configurations for control panel applications in welding machines, air conditioning units, tooling machines, medical systems, and X-ray equipment. The devices feature up to seven modules, two shaft lengths, and 29 terminal styles. Offered in shaft and panel-sealed versions, the P11P and P11D provide up to 21 indent positions along with rotary switch options.
The new Vishay Sfernice devices offer a typical operating torque from 0.3 oz. to 1.4 oz. per inch, and an end stop torque of 6.8 lb. per inch. The potentiometers provide a resistance range from 20 Ω to 10 MΩ with a typical contact resistance variation down to 1%, and TCR down to ±150 ppm/°C. Tested in accordance to CECC41 000, the devices offer an operating temperature range of -40°C to +100°C to ensure reliable operation even in extreme environments.
