If the maximum pushing pressure (pushing movement) of the electric cylinder is greater than the sensor range, the maximum closed-loop pushing pressure is the maximum value of the sensor range;If the maximum pushing pressure (pushing motion) of the electric cylinder is less than the sensor range, the maximum closed-loop pushing pressure is the maximum pushing pressure of the electric cylinder.

In electric gripper or servo gripper, the motor controls the movement of the jaw through the electrical input of the robot controller. These robot arm end tools are increasingly appearing in the industrial market. Here are five advantages of using electric grippers compared with other types of robot grippers.

1. Control the position of the gripper fingers
    By using a coded motor and an appropriate control scheme, an electric fixture can be used to determine the position of the jaw. On the contrary, for traditional grippers, the full stroke must always be maintained. When using the electric gripper, you can flexibly use only the minimum necessary clearance to approach the part, and then make the minimum travel to pick it up. Partial opening and closing help to select a wider range of part sizes without affecting the production cycle.
2, Control grip and speed
    Since the motor current is directly proportional to the applied torque, the tooth force applied by the teeth can be controlled. The same is true of the closing speed. For example, this can be helpful when dealing with fragile parts.
3. No gas pipe: save power and maintenance costs
    Many companies are switching from pneumatic to electric to reduce operating costs.An important aspect of this transformation is to reduce the cost of pneumatic hardware and energy cost.
4. Test grip strength
     Using the encoder, you can determine whether the gripper picks up the part. Some electric grippers transmit this information back to the robot controller. In many applications, in order to prevent errors, the handle must be detected. Doing this at the gripper level avoids putting other sensors in the loop, simplifying integration and reducing overall costs.
5. Cleaner grip
    Some applications require a clean environment, otherwise air leakage may lead to pollution. In this case, the electric gripper is the only feasible solution to pick up parts.

A soft force servo gripper is a device that can grip an object with a soft, compliant force. This type of gripper is often used in applications where it is important to avoid damaging the object that is being handled. Soft force servos are also well-suited for applications where a high degree of dexterity is required, such as in robotics assembly tasks.

Soft force servo grippers typically use servo motor actuators to generate the forces needed to grip an object. The actuators are connected to a controller, which is used to generate the desired gripping force. The controller is typically either a dedicated microcontroller or a general-purpose computer.

The main advantage of soft force servo grippers is that they can apply a large amount of force without damaging the object that they are gripping. This is because the actuators used in these grippers are designed to generate a large amount of force without causing any permanent deformation to the object. This makes them ideal for applications where a high degree of accuracy is required, such as in assembly tasks.

Another advantage of soft force servo grippers is that they can be used in a wide range of applications. This is because they are available in a variety of sizes and shapes, and can be customised to suit the specific needs of the application.

The main disadvantage of soft force servo grippers is that they are more expensive than traditional grippers. This is because the actuators and controllers used in these grippers are more complex and expensive to manufacture.

Soft force servo grippers are widely used in a variety of applications, such as robotics, assembly, and packaging.
