The DC control tool is a reliable robotic spindle system engineered for precise, accurate and repeatable torque control. The high performance automation fastening system allows manufacturers to optimize the assembly area, reduce labor costs and increase productivity. The robotic screwdriver system features built-in error-proofing data and screw counter. Multiple fastening strategies can be implemented for sensitive or of difficult assembly joints. Increase productivity as one tool can be programmed to do the job of multiple conventional tools; saving time, maintenance cost, space & training. Note: The E/C and A/C models are equipped with a bit cushion. Each AD robotic spindle screwdriver is supplied with the standard 3 meter length spindle cable set. The driver cable connects the AD-Series robotic screwdriver to the ADC controller. Model:AD150R02-A Drive Size:1/4" F/Hex Range: 38.4 - 274.6 cN.m ,3.4 - 24.3 lbf.in, 4 - 28 kgf.cm.
