Strategi automation solutions offers a wide range of incremental and absolute optical shaft angle encoders from bei, industrial encoder division, us. Emi shielding, abec class 7 bearings and 1 or 2-channel quadrature outputs are standard features. A wide variety of user options like light and heavy duty models; output terminations; supply voltages; complementary and index outputs; dual resolutions; u, v and w tracks for commutation of brushless servomotors; sine wave and pulsed outputs are available. Up to 3,600-ppr is available on the code disc. Interpolation is used to electronically subdivide the base resolution. Interpolative multipliers of 2,5,10 and 20 are readily available. The interpolated signal can be further multiplied through the quadrature detection method, which can usually derive up to 4x the basic code resolution. Hence, incremental resolutions up to 288,000 counts per turn can be provided through a combination of direct read on the code disc and various multiplication techniques. Special models are available for heavy loads, shock load, corrosive wash down, dirty, high temperature explosion-prone and electrically noisy environments. Application area; include machine tools, textile equipment, robotics, instrumentation and precision computer peripherals.
