Product Description:
The RL2-542DBB motor power cable is produced by Bosch Rexroth Indramat in the RL2 Motor Power Cables series. It supplies three-phase power and protective earth between 2nd-generation drives and motors, forming part of the Rexroth Cable product group for energetic, cyclic-motion machinery.
The flex chain life reaches 5,000,000 bending cycles, a value that supports long service in continuously moving assemblies. During motion the cable may be routed down to a dynamic radius of 7.5xD, while its basic design with 4× L power cores plus 4× 0.75 mm² control pairs maintains clear segregation of functions. Each power conductor has a cross-section of 1.5 mm² and is insulated for a rated voltage of 600/1000 V, allowing connection to servo inverters without derating. Copper strands may reach a conductor temperature of 90 °C before thermal limits are approached, enabling high current density during acceleration peaks.
When stationary the cable can be installed to a static radius of 5xD, reducing enclosure depth in compact machines. Electrical integrity is supported by a minimum insulation resistance of 20 MΩ/km, limiting leakage currents even after years of flex stress. A robust PUR (orange RAL 2003) jacket resists oils and abrasion, and the assembly remains flexible down to −20 °C in motion and −30 °C when fixed. Flexible operation is permitted up to +60 °C, while fixed routing can tolerate +80 °C, matching typical cabinet ambient ranges. Separate signal cores are rated 450/750 V, and the overall geometry matches the requirements of the 2nd motor generation.
Wake Industrial stocks this cable, can arrange same-day shipping, and keeps quotations valid for 30 days.
