A4/E: 4 hydraulic lines and one electrical cable, with spring return. Published maximum flow rate 40 l/min; maximum 50 V and 5 A. Hoses and conductors are selected for each configuration.
Specify the full code, suffixes and quantity; attach a photograph of the nameplate and hose/cable assembly. For a new configuration, specify 4 hoses, diameter, usable length and electrical data.
Right-hand A4D or left-hand A4S models; optional /VD vertical downward travel. 400 bar execution, mA connection or bus on request. Suitability must be confirmed for the complete assembly requested.
Suffix /En indicates the number of conductors. The cross-section depends on the hose diameter and type: use the combination published below. Unlisted combinations must not be inferred from another size.

Example code: A4D400.06.R7/E2. The size number is not always the actual side plate diameter: for example, size 320 here corresponds to 325 mm. Specify whether hoses are required when enquiring.
Dimensions in millimetres. Dimension A depends on the electrical suffix; B to E depend on the size. The catalogue states that 2D drawings and STEP models are available on request.

Cable arrangement: the TU 4+E hose/cable assembly catalogue shows three arrangements in 5/16″ R18: central (12x1 mm² screened), lateral (12x1 mm² screened), or central inside the hose (12x0.5 mm² screened), at 210 bar. These are separate assemblies to assess; they are not automatic replacements for the R7/R8 combinations above.
Tell us the number of hydraulic lines, cable voltage and number of conductors, usable length and the machine to be equipped.
