What the carrier is, and why a spare set exists
The LXMMC12CA5XS100 is a carrier listed under the Lexium MC12 multi carrier range, classed as a spare-part accessory rather than a drive itself — it is the mechanical/component carrier that supports the MC12 modular servo build, sold as a set of 10 pieces so a panel builder can keep a bench-drawer full rather than scrounging one at a time.
Footprint — 145 × 50 × 92 mm
The carrier measures 145 mm deep, 50 mm wide, and 92 mm long, so it slots into the standard MC12 modular envelope and parks alongside the drive modules in the same cabinet footprint without forcing a panel revision. Because it ships as 10 pieces per set with a single-unit carton count, stocking the full set covers a typical multi-axis build plus the spares an MRO bench wants on hand when an MC12 carrier gets damaged during a swap-out.
