Extending the sensor cable
To lengthen the sensor cable, be sure to use a HORIBA Advanced Techno extension cable
(C-7E) and relay box (CT-20CR) exclusively for this purpose.
The max. extendable length from the HR-200 to the sensor is 40 m.
The extension cable should be passed through metal conduit pipes to prevent electrical noise.
