Mechanical Integration
The tapered shaft provides a rigid connection without an additional rotor coupling. The stator coupling accommodates mounting tolerances and thermal expansion. Check the shaft fit, electrical connection, and drive configuration before installation.
Application Areas
Designed for servo motor feedback in industrial motion control. Application areas include CNC machine tools, automated production equipment, and precision positioning systems. The receiving drive must support the encoder’s EnDat interface.
FAQ
Q1: Is this a singleturn or multiturn encoder?
A: Singleturn, with absolute position feedback within one revolution.
Q2: What supply voltage does it require?
A: 3.6–14 V DC.
