LEHR is an electric gripper with a universal mounting interface and plug-in software compatibility with several collaborative robots. The gripper's motor has an integrated controller, enabling operation with a single cable with M8 connector. Rounded edges and corners offer safer human interaction and low risk of collision injuries in the cobot environment. Two body shape choices offer versatility with an application's spatial constraints. A self-locking mechanism saves prevents drops after power loss, while saving energy during gripping and standby.
