Absolute encoders have an encoder disc which has marks or slots on a power-transmission shaft and a stationary pickup. The disc records a unique code for each shaft position.

In application, absolute encoders are required if a particular setting must be recognized and available after the system powers down. All other applications can use an incremental encoder.

There are three basic configurations for optical encoders: incremental, absolute, and multiturn absolute encoders. Each delivers different performance characteristics, capabilities, and benefits.

The dual encoders are incorporated in essentially the same package size as the long-standing FHA-C mini single incremental encoder version. Without increasing the size, the dual absolute encoder ...

POSITAL’s heavy-duty IXARC incremental and absolute rotary encoders are built to stand up to extreme environmental conditions.
