AB 47CN4-4002 Multi-turn absolute encoder

Allen-Bradley 47CN4-4002 Overview

The Allen-Bradley 47CN4-4002 is an absolute encoder belonging to the Bulletin 847 series. Absolute encoders retain their position information even after a power loss, making them ideal for applications requiring precise position feedback.

Product Detailed Description

• Function:

• Provides absolute position information of a rotating shaft.

• Each position has a unique digital code that is maintained even after a power failure.

• Output signals are typically parallel, SSI, or other digital interfaces.

• Features:

• Rugged industrial-grade design suitable for harsh environments.

• High resolution providing precise position feedback.

• Multiple mounting and connection options.

• Absolute position information eliminates the need for homing after startup.
