INTRODUCTION

High Flexible Encoder Control Cable is a professional low-capacitance signal transmission cable specially developed for encoder position feedback and motion control systems. Different from ordinary power cables, this high-flex signal cable adopts precise twisted pair structure and full EMC shielding design to ensure zero-delay, lossless transmission of pulse signals, position data and speed feedback data. Equipped with VDE Class 6 ultra-fine stranded copper conductors and flexible industrial sheath, it supports long-term reciprocating bending in drag chains, effectively solving signal drift, data loss and equipment alarm caused by frequent movement and electromagnetic interference. Widely used for servo encoders, incremental encoders and absolute encoder signal connection in industrial automation equipment.

FAQ

Q1: What is a flexible encoder control cable used for?

A1: It is a dedicated high-precision signal cable for servo encoders, used to transmit speed, position and pulse feedback signals between encoders and drives, ensuring accurate closed-loop motion control for automated equipment.

Q2: Why cannot use ordinary control cable for encoder signal?

A2: Ordinary cables have high capacitance and no twisted pair balance structure, which easily cause signal delay, crosstalk and position drift, resulting in servo alarms and machining errors.

Q3: Does encoder control cable need shielding?

A3: Yes. Encoder signals are weak low-voltage pulse signals. Double shielding effectively filters EMI interference from power cables and inverters to guarantee stable feedback data.

Q4: Is this encoder cable suitable for drag chain installation?

A4: Yes. Adopting VDE Class 6 high-flex structure, it supports millions of repeated bending cycles, specially designed for moving drag chain and robotic axis applications.

Q5: Do you support custom encoder cable specifications?

A5: We support custom twisted pair counts, wire gauge, cable length, PUR/PVC sheath and connector assembly, with free testing samples and factory wholesale price.
