Product Description:
Bosch Rexroth Indramat supplies the RLB2-064JEB as part of the RLB Motor Power Cables series. This flexible power cable connects a synchronous motor to a drive controller in automated machinery. It delivers three-phase motor power and provides a protective-earth connection while moving inside drag chains or cable tracks. Standardized insulation materials and connector geometry support consistent routing across packaging equipment, material-handling systems, gantries, and other moving machine assemblies. The flexible construction accommodates repetitive travel without requiring rigid conduit along the moving axis.
The cable has a rated service life of up to 5,000,000 flexing cycles, supporting applications with frequent and repetitive movement. Its current-carrying capacity is 71.3 A, which is the maximum continuous current the conductors can deliver without exceeding the permitted temperature rise. Each main power conductor has a cross-sectional area of 16.0 mm² (AWG 6), helping limit voltage drop over extended cable runs. During dynamic operation, the cable requires a minimum bend radius of 7.5 × D, where D represents the cable’s outside diameter. Cable tracks must maintain this clearance to reduce mechanical stress on the conductors and insulation during repeated travel. For stationary routing, the cable permits a minimum bend radius of 5 × D, allowing tighter placement where continuous movement does not occur.
The motor end uses a keyed M58 circular connector that ensures correct coupling orientation and preserves the intended phase arrangement. Its internal conductor layout is 4x L + 4x 1.5 mm², combining four main power conductors with four smaller auxiliary conductors for brake or sensor power. Compatibility with ctrlX DRIVE inverters provides a direct connection to the intended drive platform. The cable also supports the MS2(X) motor family, allowing power and auxiliary functions to pass through a single cable assembly. Its Basic cable design reduces the outside diameter and overall weight compared with larger cable arrangements. Lower cable mass reduces drag on moving axes and decreases the mechanical load placed on drag chains and cable carriers during repeated motion.
