Why Use Ceramic?
Ceramics have superior mechanical, electrical, and thermal properties ideal for quality components. the durability of fine ceramics makes it ideal for mechanical and thermal loads that are abrasive and in chemically harsh environment.

Application Note

In robotics, an end-effector is a device or toll connected to the end of a robot arm. The structure of an end effector (see figure on the left and right), and the nature of the programming and hardware that drives it, depends on the intended task.

A robot arm can accommodate only certain end-effector task modes without changes to the ancillary hardware and/or programming. It is not possible to directly replace a gripper with a screwdriver head, for example, and expect a favorable result. It is necessary to change the programming of the robot controller and use a different set of end-effector motors to facilitate torque rather than gripping force. Then the gripper can be replaced with a driver head.
