Siemens 6SL3055-0AA00-5CA2 Sensor Module For Incremental Encoder

Siemens 6SL3055-0AA00-5CA2 is the SINAMICS SMC30 cabinet‑mounted Sensor Module designed for incremental encoders. It supports TTL/HTL or a combi encoder interface (SSI) with incremental tracks or an SSI encoder without incremental signals, and it is specified for use without a DRIVE‑CLiQ cable. The module is 30 mm wide and intended for cabinet installation, aligning with the SMC30 family for reliable encoder feedback in SINAMICS drive systems. Siemens’ documentation notes that this exact 6SL3055-0AA00-5CA2 variant is the supported SMC30 sensor module for SINAMICS DCM configurations, while the 50 mm width variants 6SL3055-0AA00-5CA0 and 6SL3055-0AA00-5CA1 are not compatible with DCM. In practice, this sensor module provides the encoder interface fundamental to precise motion control in SINAMICS servo and drive applications, delivering flexible encoder compatibility in a compact, cabinet‑mounted form factor.
