Insertion force attenuates after tens of thousands of cycles and nobody can prove it? 3-station endurance machine runs independent programmes and stores load-attenuation curves automatically

The problem

Connector endurance runs of tens of thousands of cycles cannot be done by hand with consistent force, speed and stroke; insertion-force attenuation has no curve evidence and disputes follow; single-station machines queue one sample at a time; and dynamic contact impedance during cycling is beyond ordinary machines.

Capability

Three independent endurance modules with per-station control and 50kg load cells by three; cycle count 1-9999999 continuous or single; test stroke 0-90mm (max measuring stroke 150mm); speed 0-200mm/s (0.5-300mm/min adjustable); load ranges 5/10/20/50/100kgf selectable with 0.01 resolution and N/Lb/gf/Kgf conversion; displacement resolution 0.01mm with low/mid/high manual fine speeds; 360-degree floating head on the fixture with three auto-centring units and three multi-function fixtures; XY stage 0-80mm and Z axis 0-100mm manual fine adjustment; high-precision ball-screw drive with closed-loop servo motors; left-right space at least 230mm and up-down at least 300mm; 7-inch touch screen sets test type, direction, load range, stroke, origin, speed, total count, dwell time, waiting position and blank cycles; upper and lower limits stop the machine automatically; insertion-withdrawal stroke curves, load-attenuation life curves and reports with editable bilingual headers, exportable to Excel or Word; optional dynamic impedance system plotting load-impedance-stroke curves; overload protection, emergency stop, stroke limiters and software limits; frame approx. 1380x880x960mm, AC220V/50Hz, 1kW.
