RKL0042 by Bosch Rexroth Indramat

The RKL0042 motor power cable is manufactured by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed for automated assembly lines, packaging machines, and robotics, it links servo drives to motor terminals while carrying both main phase current and auxiliary signals. Its construction supports continuous motion in cable carriers, allowing dependable power delivery along dynamic industrial paths. The cable's profile also fits molded connectors typically used in Rexroth drive systems, simplifying installation and routing inside tight control cabinets.

Electrical capacity is based on a power conductor cross-section of 10.0 mm², giving sufficient ampacity for medium-frame servo motors at standard drive voltages. Control logic or brake release circuits are served by an auxiliary pair sized at 1.0 mm². To minimize I²R losses along extended routes, the copper strands exhibit a resistance of 1.91 ?/km when measured on 10 mm² cores. Mechanical endurance is rated for 5,000,000 bending cycles in energy chains, so repeated reciprocating travel does not compromise insulation. Visual identification inside crowded wiring ducts is aided by the jacket color of Orange (RAL 2003), which follows the color convention for motor power conductors in Rexroth drive packages.

The external sheath is made of PUR, a thermoplastic polyurethane that resists oils, welding sparks, and abrasion common in factory environments. The overall cable diameter is 22.2 mm, which matches standard gland sizes for IP-rated motor connectors. In fixed routing, the cable can be laid with a minimum bend radius of 5 x D, while continuous-flex applications require a minimum bend radius of 7.5 x D to reduce conductor fatigue. Temperature stability extends from -30 °C to +40 °C in fixed routing and from -20 °C to +40 °C during continuous flexing, covering most indoor machine hall conditions.
