SEW-EURODRIVE EI7 B DR90 Rotary Encoder Module

The SEW‑EURODRIVE EI7 B DR90 drive encoder module provides HTL incremental feedback for DR90/DRN90 AC motors, delivering reliable speed and position data for closed‑loop motor control. Designed as an integrated motor encoder module, it is commonly installed on conveyor drives, packaging machinery, material handling equipment, and other automated production systems that rely on SEW DR90 motors for precise feedback. Key specifications include an incremental encoder with HTL output, supply voltage 9–30 VDC, maximum current consumption 120 mA (no load), maximum pulse frequency 2.4 kHz, and a maximum speed of 6000 RPM. Applications include encoder replacement, motor repairs, retrofit projects, and restoration of SEW drive systems by maintenance teams, OEM engineers, and system integrators in industrial automation and motor feedback contexts.
