61KS256 Encoders

Incremental encoders are devices that relatively measure the angular displacement of an axis, usually with an optical or magnetic sensor attached to the rotating element and a scale pattern attached to the stator which may produce an electrical signal upon detection of displacement.

Application Field

61KS256 encoders are most typically used for motor feedback and control applications such as robotic systems, automated assembly, and machine interfaces. As it contains several different types of technology, the 61KS256 can be used to measure the motion of high-speed rotations, low-speed operations and wide-ranged angles. Additionally, its stroke connecting interface is able to convert the signal to incremental interfaces. It is also used in agricultural machinery, metering systems, pumps and motors, and similar instruments.

Working Principle

The 61KS256 encoders use a unique combination of traditional incremental signals, multi-turn signals, and SSI signals. It is composed of a scale plate and a reading head at the two ends. The scale plate is fixed in the motor base, and the rotating shaft of the motor has a rotary block to adjust the reading head with the scale plate. It consists of two optical receiving parts that can distinguish light and dark accurately. The moment the wheel began spinning, the non-contact optical read head will detect light and dark levels on the nearby scale plate and can precisely detect displacement of up to 2,097,152 counts per revolution for fast motion control.

In addition, the 61KS256 encoder is designed to produce positive, negative, and index/alarm pulsings for digital control systems which are both stable and precise. It is also capable of sending multi-turn information which can be used to identify total amounts of rotations. This feature is very helpful in providing long-term accuracy as well as extended motion capabilities due to its magnetic scan sensor which can measure up to 65535 revolutions.
