Catalog excerpts

OPH is a sealed two finger parallel gripper featuring high process reliability, suitable for handling of rough or dirty workpieces. Advantages • Robust and lightweight housing made of hard-coated aluminum alloy. • Lip seal at the round jaw guidance for permanent, secure gripper sealing. • Wedge-hook design for high power transmission and synchronized gripping. • Compact dimensions for minimal impact in customers' applications. • Mounting from two sides in three screw directions for universal and flexible gripper assembly. • Integrated permanent magnets for direct monitoring of piston movement. • Slots for mounting and positioning of magnetic field sensors. • Air supply via hose-free direct connections or fitting screw connections. SPECIFICATIONS Model Air Consumption Per Cycle (Dual Stroke) Closing Force Per Jaw @ 6 bar Opening Force Per Jaw @ 6 bar Recommended Workpiece Weight* Weight Repeatability Opening Pressure Working Temperature Noise Emission (Sound Pressure) * Recommended workpiece weight is calculated for force-fit gripping with a static Coefficient of Friction of 0.15 and a Safety Factor of 3 against workpiece slippage. SECTIONAL DIAGRAM Guidelines for the selection of a gripper model Selection of the correct gripper model depends on the workpiece's weight, the friction coefficient between the fingers and the workpiece and the required motion of the application. Due to inertial forces associated with motion, the gripper model should feature a holding force from 10 to 20 times the workpiece's weight. If the application presents high acceleration/deceleration or impact during the motion then a further safety margin should be considered.
