  • Compatible with many brands of assembly system



HYDRAULIC SPEED CONTROL precision hydraulic control of the melt velocity. Critical to achieve maxi­mum weld strength in staking, inserting and shear joint applications.

LINEAR OPTICAL ENCODER Ability to weld by collapse and absolute distance through out 7 inches of stroke with .0005 of an inch resolution. (requires DPC III or IV Plus w/ distance module)

PRE-TRIGGER and END-of-WELD LIMIT SWITCHES Pre-trigger provides ability to initiate weld (sonics on) phase of the cycle prior to contacting part. Great for staking applications. End of weld provides ability to weld to predetermined position in the stroke, simple absolute distance.

38mm, or 51mm  or 63mm and 76mm air cylinder

OPTICAL cycle activation switches
