Product Description:
The ZK1090-6161-0250 is a pre-assembled motor cable from Beckhoff that belongs to the ZK Motor Cables series. It serves as the movable link between drive controllers and field-mounted actuators in automated production cells, carrying both supply power and digital feedback through an M12 interface. Built for continuously flexing cable chains, the assembly supports high cycle counts without compromising signal integrity or mechanical reliability in industrial automation.
This model ships in a fixed length of 25.00 m, providing a ready-to-route harness for medium-distance motor runs inside large machines. Its plug side follows the D-coded pin arrangement, so it mates directly with matching Ethernet-based or sensor ports on Beckhoff I/O components. Inside the jacket, the core set is 1 x 4 x 0.34 mm² (AWG22), and each conductor is built from 7 strands of 0.25 mm wire to balance flexibility with current-carrying capability. A tough PUR (polyurethane) outer sheath resists oils, welding sparks, and constant chain motion. When ambient temperature stays at 40 °C or lower, each position of the M12 connector can deliver up to 4 A (40 °C), supporting low-power servo axes or auxiliary actuators without overheating.
During operation, the cable can travel at line speeds of up to 4 m/s and withstand acceleration peaks of 4 m/s², while its flex-rated design endures up to 3 million bend cycles in energy-chain applications. Data integrity over long runs is supported by a mutual capacitance of 52 nF/km (1 kHz), and signal delay is 5.3 ns per meter, allowing deterministic timing in distributed motion networks. The insulation system tolerates surge events up to 2.5 kV, and the knurled coupling nut is tightened to a recommended 0.6 Nm to maintain IP protection and strain relief at the connector interface.
