MR-J4 Compatible Encoder Cable Kit — Low-Loss Twisted Pairs for Servo Axes
Encoder cable kit compatible with all Mitsubishi Electric MR-J4 and MR-J4W servo amplifiers. Set includes two 3-metre PUR-jacketed cables rated for oil and industrial fluid environments, double-shield construction (aluminium foil + copper braid earth), low-tolerance twisted pairs at 110 Ω characteristic impedance to minimise positional jitter on sensitive axes. Each cable TDR-tested for pair integrity with test sheet enclosed. IP67 locking connectors at both ends vibration-resistant; fully pin-compatible with MR-J4 factory harness. Suitable for high-speed axes up to 6,000 RPM and encoder resolutions up to 26-bit. Designed for CNC machines, serial-link robots and servo presses.
