PFH-mn General notes about the seres Operatng prncple: Double pston rack and pnon prncple Housng materal: Alumnum alloy, anodzed Base jaw materal: Steel Actuaton: pneumatc, wth fltered compressed ar as per ISO 8573-1:2010 [7:4:4]. Warranty: 24 months Scope of delvery: Bracket for proxmty swtch, centerng sleeves, O-rngs for drect connecton, assembly and operatng manual wth Declaraton of Incorporaton. Grppng force mantenance: possble wth SDV-P pressure mantenance valve 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.the maxmum permssble fnger length apples untl the nomnal operatng pressure s acheved. Wth hgher pressures, the fnger length must be reduced proportonally to the nomnal operatng pressure. 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. Valve swtchng tmes, hose fllng tmes, or PLC reacton tmes are not a part of ths and are to be consdered when cycle tmes are calculated. Applcaton example Assembly unt for ntermedate sleeves wth varous dameters. The unt s equpped wth a collson sensor to prevent damages. 1 PFH 2-fnger parallel grpper wth workpece-specfc grpper fngers 2 OPS-plus collson and overload sensor 4
