State connector series, precision grade, gender, orientation or clocking, plating, mating torque, access and mating-cycle requirement at both ends. Define overall length, tolerance and the exact reference points used for measurement; attach a centerline drawing for formed or semi-rigid assemblies.
Separate minimum static and dynamic bend radius. Define movement plane, travel, torsion, cycle count, speed, clamp locations, strain relief, unsupported mass and keep-outs, and prohibit bending at the termination unless the supplier has qualified that geometry.
Ask for assembly-level S-parameter evidence in the delivered route and for dimensional inspection where shape is controlled. Any connector, length, bend or support change should trigger configuration review rather than inheriting the previous approval automatically.
