MA780GQ傳感器變送器的位置傳感器-角度、線性位置測量規(guī)格書PDF中文資料

MA780GQ屬于傳感器變送器的位置傳感器-角度、線性位置測量。由美國芯源系統(tǒng)有限公司制造生產(chǎn)的MA780GQ位置傳感器 - 角度、線性位置測量角度和線性位置測量傳感器使用電容、霍爾效應(yīng)、電感、LVDT、LVIT、磁阻、光學(xué)或電阻技術(shù)，來確定傳感器的致動器相對于參考點的位置。角度位置傳感器可根據(jù)有限或連續(xù)旋轉(zhuǎn)范圍內(nèi)的電氣或機械范圍進行區(qū)分。線性位置傳感器可根據(jù) 0 到 400 英寸的范圍進行區(qū)分。其他考慮因素包括致動器類型、輸出類型和信號、安裝類型和線性度。

DESCRIPTION

The MA780 is a low-power angle sensor that

detects the absolute angular position of a

permanent magnet, such as a diametrically

magnetized cylinder on a rotating shaft. With its

power-cycling ability, the sensor is optimized for

applications that require low average power.

Timing can be controlled via an on-chip clock or

external controller. Flags are provided to detect

a definable amount of angle change.

The MA780 supports a wide range of magnetic

field strengths and spatial configurations. Both

end-of-shaft and off-axis (side-shaft mounting)

configurations are supported.

On-chip, non-volatile memory (NVM) provides

storage for configuration parameters, including

the reference zero-angle position, power cycling

parameters, and the filter window that affects the

output resolution.

The MA780 is available in a QFN-16 (3mmx3mm)

package.
