With high-performance high-resolution digital feedback in an extremely small package, the new DataTorque SM7 provides the type of resolution and performance common with much larger encoder packages. The SM7 has a patent pending new sensing scheme and a much simplified encoder design, resulting in a longer service life with less downtime (from feedback device failure). It delivers high noise immunity.
The DataTorque SM7 is miniature in size, only 0.787 inches (20 mm) in diameter, yet provides resolutions up to 2,048 lines. Output variations include single-ended, open collector, internal pull-ups or RS-422A differential line driver.
DataTorque SM7 has low supply current requirements, 5v or 5 to 26 VDC, reducing inventory requirements. It is constructed of a conductive carbon fiber composite that provides the EMI shielding of an all-metal housing.
