Product Description:
The ZK4000-6200-2050 is a pre-assembled motor cable from Beckhoff's ZK Motor Cables series. It is supplied with a molded M12 socket on one end and is used in industrial automation to carry power and low-level feedback between drives and compact servo motors. This layout suits decentralized motion systems where small servo axes need a ready-made connection instead of field termination. By matching the mechanical coding of field devices, it streamlines cabinet wiring and reduces setup work on modular production lines.
The cable diameter is held to 5.35 ± 0.15 mm, which helps it fit standard strain reliefs, conduit entries, and drag-chain clamps. Its conductors use a 4 × 0.5 mm² (AWG20) layout with a 28 × 0.15 mm fine-strand construction, which improves flexibility during repetitive motion and helps reduce strand fatigue. The connector uses the industry-standard M12 interface with A-coded keying to prevent mismating when similar circular connectors are installed nearby. Electrical ratings reach 250 V phase to phase, and the copper cross-section supports up to 5 A at 40 °C without exceeding normal thermal limits. The socket uses female contacts arranged in a four-pin pattern that follows IEC pinouts for consistent mating with compatible devices.
For moving-cable applications, the design endures up to 4 million flex cycles when installed with a bend radius matched to its outer diameter. The nickel-plated coupling nut is tightened to 0.6 Nm, helping maintain a secure connection under vibration, and surge levels up to 1.5 kV are tolerated between conductors and ground. A tough PUR outer jacket resists oils and welding sparks, while the factory-cut 5.00 m length avoids on-site trimming and keeps routing predictable in compact machine layouts. Because no overall braid is fitted, the cable is unshielded, which keeps the construction simple for applications that do not require shield continuity. The molded connector body also supports repeated handling without the added assembly steps of separate field-wired terminations.
