P11P and P11D panel potentiometers

Vishay Intertechnology Inc. has announced two compact panel potentiometers with high dielectric strength of 5,000VRMS.

With their 12.5mm size, the new P11P and P11D offer designers a compact alternative to other low-cost panel potentiometers. The P11P's cermet element provides better stability than carbon elements, while the conductive plastic element of the P11D offers a reduced electrical noise for audio applications. Both devices feature a 5,000VRMS dielectric strength for greater reliability, robustness and corrosion protection, and offer insulated plastic shafts and bushing, with value-added options in accordance with drawings supplied by customers.

The 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 0.3oz. to 1.4oz. per inch, and an end stop torque of 6.8lb. per inch. The potentiometers provide a resistance range from 20 to 10M with a typical contact resistance variation down to 1 percent and TCR down to 150ppm/C. Tested in accordance to CECC41 000, the devices offer an operating temperature range of -40C to +100C to ensure reliable operation even in extreme environments.

Samples and production quantities of the new panel potentiometers are available now, with lead times of eight to 10 weeks for larger orders.
