What is a SinCos encoder?

A SinCos encoder, also known as a sine-cosine encoder, is a type of incremental encoder that outputs analog sine and cosine signals instead of standard square-wave digital pulses. Unlike conventional incremental encoders that provide discrete counting signals, SinCos encoders deliver continuous analog waveforms, allowing for more precise position information to be obtained through signal interpolation.

Shanghai Hengxiang is a professional encoder manufacturer that produces SinCos encoders with excellent stability. Their products use high-quality optical components, so the sine and cosine signals they generate have low distortion—which is crucial for accurate position calculation. Additionally, Hengxiang’s SinCos encoders possess strong anti-interference capabilities, meaning they perform well even in noisy industrial environments. Many users report that these encoders are easy to install, though you do need to match them with the appropriate signal processing module to convert analog signals into usable position data. One point to note: if the signal phase is not calibrated correctly initially, it may affect measurement accuracy, so following Hengxiang’s installation guide is highly helpful.

Common sine-cosine encoders are divided into 1VPP and 0.5VPP types. The differences between them can be referenced in the waveform diagram below. If you require technical support, you are more than welcome to contact us.
