Shielded Cable Harness for Vibration Sensor Arrays

Product Specifications

Technical details and manufacturing context for Shielded Cable Harness

Definition

A shielded cable harness is a critical component within vibration sensor arrays that bundles multiple shielded cables together with connectors and protective sheathing. It ensures reliable transmission of sensitive vibration measurement signals from sensors to data acquisition systems by providing electromagnetic shielding, mechanical protection, and organized routing within industrial environments. The harness typically consists of copper conductors insulated with polyethylene or PVC, surrounded by copper braid and aluminum foil shielding layers, and finished with a PVC or nylon outer jacket. It is available with 2 to 60 conductors, conductor cross-sections from 0.14 to 2.5 mm², rated voltages from 30 to 600 V, and rated currents from 1 to 16 A per conductor at 40°C ambient. Shielding effectiveness ranges from 60 to 100 dB at 1 GHz, insulation resistance is at least 100 MΩ·km at 20°C and 500 V DC, and conductor resistance for a 1.0 mm² copper conductor is ≤13.7 Ω/km. The operating temperature range is -40 to 105°C, with a bending radius of 5 to 10 times the outer diameter for static installation. Ingress protection ratings vary from IP54 to IP67 depending on connector and sealing. Connector types include D-Sub, RJ45, and M12, and cable outer diameter ranges from 4 to 20 mm, with weight from 50 to 500 g/m. These values are directory reference ranges; actual specifications must be confirmed with the legal manufacturer or supplier for the specific model and application. The harness is designed for use in computer, electronic, and optical product manufacturing, particularly in vibration monitoring systems where signal integrity is paramount.

Working Principle

The shielded cable harness operates by using conductive shielding layers (typically braided copper or foil) around individual conductors or the entire cable bundle. This shielding creates a Faraday cage effect that blocks external electromagnetic interference from corrupting the sensitive vibration signals. The harness organizes multiple sensor connections into a single, protected assembly that maintains signal integrity while withstanding mechanical stress and environmental conditions.
