Siemens 6SE6400-0EN00-0AA0 Micromaster 4 Encoder Module

Siemens 6SE6400-0EN00-0AA0 Micromaster 4 Encoder Module is a dedicated encoder option for MICROMASTER 4 drives that adds an incremental encoder interface for precise motor feedback. It supports TTL differential and HTL incremental signals and provides ENCA, ENCB, ENCZ, and ENC-REC connections, enabling accurate position or velocity feedback with a maximum encoder frequency of 300 kHz. The module can be powered from a 5 V supply (±5%, up to 330 mA) or a 24 V supply (unregulated, up to 140 mA), with a typical power draw of about 3 W. Its compact form measures roughly 161 mm × 73 mm × 42 mm and carries IP20 protection for use inside control cabinets; operating conditions specify -10 °C to +50 °C and up to 85% relative humidity non-condensing. Designed specifically for MICROMASTER 4 series, this encoder option module enables robust closed-loop feedback for accurate speed and position control in industrial automation and motion control applications.
