RG2-012AAB by Bosch Rexroth Indramat

The RG2-012AAB is an encoder cable from Bosch Rexroth Indramat that belongs to the RG2 Encoder Cables series. It links the digital encoder of an MS2M synchronous motor to the matching ctrlX DRIVE controller, carrying position and speed information between the motor and drive for closed-loop operation. In automated lines, the assembly serves as a dedicated feedback channel so drives can correct motion accurately during synchronized starts, stops, and speed changes across multi-axis equipment.

Mechanical endurance is rated for 5,000,000 bending cycles. This indicates how many repetitive flexes the jacket and conductors can withstand in a cable track. A conductor cross-section of 0.50 mm² helps limit voltage drop while keeping the overall diameter compact. Each end is terminated for an M17 motor bayonet connector, enabling direct connection without separate adapter hardware. Dynamic routing in energy chains is allowed at a minimum radius of 7.5 × D, while stationary routing may tighten to 5 × D to reduce conductor stress under different installation conditions. The design is part of the Basic second-generation portfolio and uses digital cabling to support digital encoder signals.

Thermal suitability spans from -40 °C to 80 °C, permitting service in unheated warehouses or near warm machinery without harming insulation performance. Electrical pinout and shielding comply with the ctrlX DRIVE-CN (XCS2-F) interface, helping preserve signal integrity when paired with the corresponding MS2M motor family. Because the assembly is supplied as a single cable, no intermediate breakout boxes are required, which shortens the connection path and reduces potential points of noise ingress. These handling limits suit conveyor, pick-and-place, and material-handling axes that operate around the clock and bend repeatedly in compact cable carriers.
