OnRobot Soft Gripper tool SG-a-H

The SG-a-H is a silicone gripping tool for the OnRobot Soft Gripper. It is an accessory and works only with the Soft Gripper base part (item 103546, sold separately); without the base part it cannot grip. The SG-a-H is the star-shaped tool with a hard silicone end. It has the highest payload of the three tools: OnRobot gives up to 2.2 kg, measured with a 65 mm ABS cylinder, and the real value depends on the shape, softness and friction of the item.

The grip dimensions are 11 to 75 mm with a grip depth of up to 38 mm. The tool weighs 0.168 kg including its smart-lock, measures 76 mm by 112 mm in diameter and supports up to 32 grips per minute. The tool attaches to the base part with a quick-lock and smart-lock mechanism and can be exchanged. It is made of two-component silicone rubber that complies with FDA 21 CFR 177.2600 (tested for non-fatty foods) and EC 1935/2004, is rated for 2,000,000 operation cycles and is dishwasher-safe. Sharp edges on a workpiece can damage the silicone. Compared with the soft SG-a-S, the hard end gives more payload; compared with the finger-shaped SG-b-H it covers smaller objects.

Typical applications

• Pick and place of round and compact food items, bakery items and bottles
