EGP General notes about the seres Operatng prncple: Rack and pnon prncple Housng materal: Alumnum alloy, coated Base jaw materal: Steel Actuaton: servo-electrc, va brushless DC servomotor Warranty: 24 months Scope of delvery: Enclosed pack wth centerng sleeves, mount for proxmty swtch, assembly and operatng manual wth Declaraton of Incorporaton. Grppng force: s the arthmetc total of the grppng force appled to each grpper jaw at dstance P (see llustraton). Fnger length: s measured from the reference surface as the dstance P n drecton to the man axs. Repeat accuracy: s defned as the spread of the end poston durng 100 consecutve strokes. Workpece weght: s calculated for force-ft grppng wth a coeffcent of statc frcton of 0.1 and a safety factor of 2 aganst workpece slppage at acceleraton due to gravty g. For form-ft or capture grppng, there are sgnfcantly hgher permssble workpece weghts. Closng and openng tmes: are purely the tmes that the base jaws or fngers are n moton. PLC reacton tmes are not a part of ths and are to be consdered when cycle tmes are calculated.

Please contact us for further nformaton: SCHUNK techncal hotlne +49-7133-103-2696 Optons and specal nformaton Manually adjustable grppng force: Wth an ntegrated rotary swtch, the grppng force can be adjusted n two stages for the EGP 25-100% and 50%, and n four stages for EGP 40, 50 and 64-100%, 75%, 50%, and 25%. Optonal status montorng va external sensor system: The status of the grpper can be montored by external senors. Optonal adapter plates: Space-savng frontal mountng of the grpper s enabled by optonal adapter plates. KA connecton cable: Connecton cables wth an angled or a straght female connector can be ordered n varous lengths to connect the grpper wth the power supply and hgher-level control system. Speed Verson S: for faster closng and openng tmes due to the use of a dfferent gear rato. The opton of a grppng force adjustment s no longer avalable. 5
