Product Description:

The ZK4000-6700-2050 is a motor connection cable manufactured by Beckhoff. This is a part of the ZK Motor Cables series. This component is engineered to guarantee accurate motor couplings in motion applications.

The Beckhoff’s ZK4000-6700-2050 has a total length of 5.00 meters. The insulating resistance is ≥ 1 GΩ·km and it can withstand an operating voltage of 300 V. The cable resistance is ≤ 39 Ω/km at 20°C resulting in negligible power loss. The motor cable's dielectric integrity is tested at a voltage of > 3000 V. Copper conductors consist of 28 0.15 mm strands. The conductor material is bare copper with a cross-section of 4 x 0.5 mm². It has a shield with tinned copper wire braiding for signal protection. It performs well at up to 10 m/s² acceleration and 3 m/s velocity. The outside diameter measures 6.0 mm ± 0.2 mm. The cable bending radius is ten times its outer diameter. In fixed installations the cable remains robust at temperatures ranging from -30 to +80 degrees Celsius. It has a dynamic movement range of -15 to +80 °C. The ZK4000-6700-2050 enables 4 million motion cycles. It meets IEC 60332-1-2 and DIN EN 60811-2-1 requirements for halogen-free oil and flame resistance. The plug's rated voltage is 160 V and the current is 5 A at 40 °C. Insulation resistance exceeds 100 MΩ whereas contact resistance falls below 10 mΩ.

The ZK4000-6700-2050's Head A features an M12 socket connector. It is straight having 4-pin female connections. The connector has a screw locking mechanism with a torque of 0.6 Nm. The environmental protection ratings are IP65 and IP67. It can withstand temperatures ranging from -40 to +85 °C. This cable is suitable for industrial environments with constrained spatial limitations.
