The absolute encoder provides a unique encoded position value for each position of the shaft, and is always used in angular and position measurement. It is suitable for automation applications under various industrial environments.
The heavy duty encoder generate signals through photoelectric and magnetoresistive pulse scanning, and is used for variable speed drive and control unit working in harsh environment, or having tough requirement. The heavy duty encoder is widely used in heavy machinery of the sectors such as metallurgy, wind power, petroleum, port, mine and lifting, which work under heavy load and harsh environment.
The incremental encoder is mainly used for shaft rotation speed feeding back, relative positioning control, and rotation angle and stroke measuring. The encoder provides a certain number of square wave pulses or sinus-cosinus pulse signal as the shaft rotates a certain angle.
This type of absolute encoder provides unique one-to-one encoded numeric position value of each shaft position for absolute positioning control or speed feedback mainly. The encoder is designed with the currently prevailing electrical interface. Its resolution can reach 16 bits max. for single-turn type, and 30 bits for multi-turn type. It also stands out for its high protection degree and strong anti-interference ability, and it is suitable for industrial automation application.
The magnetic absolute encoder reads the position data on the disc by sampling magnetic field variation, and provides and transmits the position value of the corresponding shaft through the SSI interface (synchronous serial interface) or the CAN bus interface. It is suitable for harsh and complicated working environment.
The explosion-proof encoder is applicable for being used in explosive and dangerous areas for speed measurement (incremental type) or distance measurement (absolute encoder). The explosion-proof encoder complies with explosion-proof standards in its mechanical structure, and it is always selected for the flammable and explosive places in petroleum, chemical, coal and other industries.
The explosion-proof encoder is mainly used for measuring and feeding back (incremental encoder) the rotation speed of the equipment installed in the explosive and dangerous areas, and used for measuring and controlling the rotation position of the important equipment. It can be prevented from ignited under explosion condition and is applicable for explosive gas environments.

As of heavy duty but compact design, this type of heavy duty encoder stands out for its excellent resistant to vibration and mechanical damage, and can withstand heavier axial and radial loads. heavy duty encoder is applicable for heavy industry and all other cases with heavy shaft load or harsh working conditions.
Functioning as a rotary sensor, the incremental encoder converts the rotation displacement signals into a series of digital pulse signals to indicate the equipment displacement result. It has advantages of strong anti-interference ability and high reliability performance. This kind of incremental encoder is mainly used for measuring speed, rotating direction, moving angle or relative distance, etc.
Based on AMR/GMR (anisotropic magnetoresistance and giant magnetoresistance) technology, and supported by LED intelligent status display and self-diagnosis functions, anti-interference RS422 line driver and push-pull transmission technology. Magnetic incremental encoder features compact design and suitable for speed measurement and positioning control of rotating mechanism in extremely harsh industrial environment.
