Pankaj potentiometers, a pioneer manufacturer of potentiometers in india has manufactured unique absolute analogue servo encoder based on hall effect technology. These servo encoders are reliable as there are no moving metallic contacts and increased rotational life expectancy and output stability. Some of the technical specifications of these absolute analogue servo encoders include 0-10v dc and 4-20 ma simultaneous dual out put; in 10-bit resolution; less than 1.4-degree non-linearity error; better than 1 % individual linearity; mechanical 360 angle rotation. These absolute analogue servo encoders are available with salient features like electrical discontinuity between 0 to 10v dc; instantaneous change over; no effect of external magnetic field on performance due to technically engineered design; differential measuring technique; sensor conditioning circuitry; 50 mm diameter rugged aluminium housing; non magnetic stainless steel spindle on double ball bearing for reliability; and mounting either by clamps or three m3 screws at 35 mm pcd.
