1 Specifications

CGC series are collaborative electric gripper, The number(CGC-number) represents the

maximum gripping force of the gripper. The gripper is equipped with a pair of parallel fingertips,
which runs symmetrically during the movement. The main structure of the gripper is a smooth
rectangular structure. It is equipped with an 8-core communication interface, as shown in Figure 1.1.
It has the following characteristics:

Controllable force/position/speed

: The gripper can program and adjust the grip position,

grip force and speed.

Multiple communication modes

: The gripper supports Modbus RTU protocol and IO mode

control. Other communication protocols such as Ethernet and ETHERNET can be transferred
through protocol converter.

Gripping Detection

: The combination of force control and position control is adopted in the

gripping process.

Gripping feedback

: The state of the gripper can be read by programming, and can also be

judged according to the indicator of the gripper.

Fingertips can be customized

: Fingertips can be replaced according to situation, which is

suitable for precision machining, parts assembly, and other fields.
