Autonics Co., Ltd. E40H8-2000-3-3-24 Rotary Encoder

Autonics E40H8-2000-3-3-24 Rotary Encoder is a 40 mm incremental encoder with a hollow shaft designed for precise rotary-position feedback in automation systems. It provides 2000 pulses per revolution (PPR) for high-resolution measurements and offers three signal outputs (A, B, Z) for standard quadrature encoding with an index pulse, enabling reliable direction sensing and reference positioning. The model denotes a 24 V DC operation, commonly used in industrial controllers, and the E40H8 designation indicates a hollow shaft with an 8 mm bore, suitable for compact installations where a through-hole or shaft coupling is required. Typical applications include motor drives, CNC machinery, packaging lines, robotics, and automated assemblies where accurate speed and position feedback are essential for closed-loop control. Key specs to consider are the Ø40 mm housing, hollow-shaft configuration, 2000 PPR resolution, A/B/Z channel outputs, and 24 V DC compatibility, all combining to deliver robust, high-precision motion sensing in demanding industrial environments.
