Product Description:
The RKL4541 is a motor power cable from the RKL Motor Power Cables series manufactured by Bosch Rexroth Indramat. It carries three-phase power and auxiliary signals between an IndraDrive controller and a servomotor, allowing the automation system to combine power and control wiring in one routed harness. This model is cut from bulk cable stock and terminated for connection to compatible motor equipment. Its integrated arrangement reduces the number of separate cable runs needed between the control cabinet and the motor. The cable is intended for industrial machinery that requires dependable electrical performance during continuous movement.
The conductor bundle originates from bulk cable type INK0607, with insulation and shielding geometry selected for Rexroth drive systems. Three power conductors, each with a cross-sectional area of 25.0 mm², carry continuous motor current while limiting voltage drop over the cable run. The cable also contains four control conductors, and each control core has a cross-sectional area of 1.5 mm² to accommodate brake, temperature sensor, or other auxiliary circuits. The conductors are crimped for a size 2 terminal box interface that matches the stud and cable-gland arrangement used on compatible synchronous motors. The cable is halogen-free, which limits the release of corrosive gases if its insulation is exposed to fire. Its internal conductor arrangement and flexible insulation support installation in continuously moving drag-chain carriers.
A chemically resistant outer sheath made from matte PUR protects the cable braid from lubricants and abrasion. The sheath uses the safety color RAL 2003 orange, making energized cable routes easier to distinguish from other wiring inside industrial machinery. In a permanently installed route, the jacket permits a minimum bend radius of 5 × D, where D represents the cable’s outside diameter. During repetitive dynamic movement, the cable requires a minimum bend radius of 7.5 × D to reduce stress on the conductors and insulation. The flexible jacket allows routing through confined energy tracks when the applicable bend radius is maintained. Resistance to common industrial lubricants helps protect the outer surface in machinery where oils and greases may contact moving cable assemblies.
