Frequently Asked Questions
Q1: What are the main features of the RM-EGB Comapct Electric Finger?
RM-EGB compact electric finger is a highly integrated unit with a built-in controller, featuring four preset force levels and three preset stroke levels. Installation and commissioning are simple and require no parameter settings, making it ideal for directly replacing pneumatic grippers of the same compact size.
Q2: What communication/control methods does the RM-EGB Comapct Electric Finger support?
The EGB supports two control methods: I/O and Modbus RTU.
- For the I/O control method, it provides 3 inputs and 3 outputs, supports NPN or PNP, and offers a wide range of I/O control combinations. Users can directly trigger I/O signals to change preset force, stroke. For example, four preset force levels can be selected directly through I/O, minimizing both learning cost and usage cost.
- RM-EGB also supports Modbus RTU (485), allowing users to modify the gripper's motion parameters through an upper computer via Modbus RTU communication.
If other communication methods are required, please refer to RobustMotion's other intelligent electric actuator series.
Q3: What does "four force levels available" mean for the RM-EGB Comapct Electric Finger?
Taking RM-EGB-06 as an example, its maximum force is 40 N.
- In I/O control mode, force can be set to four levels—10 N, 20 N, 30 N, or 40 N—by triggering different I/O combinations.
- When controlled via Modbus RTU, the adjustable force range is 10–40 N.
Q4: What is the opening and closing speed of the RM-EGB Comapct Electric Finger?
RM-EGB is available in different motion speed specifications. RM-EGB-06H-16D is the high-speed version. Its maximum opening and closing speed is 0.1 s for opening and 0.1 s for closing, which is theoretically faster than pneumatic grippers of the same specification.
Q5: What is the allowable load for the RM-EGB?
The allowable load of the gripper depends on the length of the tooling or fixtures and the weight of the load. Please refer to the product catalog for detailed specifications.
Q6: What kind of motor does the RM-EGB adopt?
Servo motor.
Q7: Does the RM-EGB have a braking function?
No. It does not include a mechanical self-locking (brake) mechanism.
Q8: In the automation equipment industry, can the RM-EGB provide high gripping force in a compact size to reduce equipment footprint?
Yes. RM-EGB delivers high force output in a compact size, making it suitable for applications with space limitations.
Q9: What other advantages does the RM-EGB offer besides high-speed opening and closing?
RM-EGB Comapct Electric Finger not only serves as a direct replacement for pneumatic grippers but also incorporates a drop-detection function that conventional pneumatic grippers do not have. It provides immediate signal feedback whenever a workpiece is not gripped or is dropped.
Q10: What are the main application scenarios for RM-EGB Comapct Electric Finger?
RM-EGB Comapct Electric Finger is used in a wide range of automation applications across industries such as 3C, optics, and medical aesthetics. It is ideal for tasks like synchronized gripping and transferring of electronic components in compact spaces during processes such as loading and unloading.
