The IAI Mini 3-Finger Gripper combines the flexibility of electric motion control with the compact footprint required for modern automation equipment. Available in both the ROBO Cylinder® and ELECYLINDER® platforms, this gripper delivers precise workpiece handling, adjustable gripping force, and multiple positioning capabilities that are difficult to achieve with traditional pneumatic grippers.
Designed for inspection stations, centering operations, assembly systems, and robotic end-of-arm tooling, the Mini 3-Finger Gripper helps manufacturers improve process consistency while reducing compressed air consumption.
- Compact design simplifies installation on robotic tool heads and machine end effectors.
- Up to 70 N of gripping force provides secure handling of a wide range of components.
- 30 mm total gripping stroke accommodates larger part size variations.
- Electric control enables programmable speed and force adjustments.
- Multiple positioning options eliminate the need for mechanical tool changes.
- Suitable for delicate, fragile, and precision-manufactured parts.
- Reduced maintenance compared to pneumatic gripping systems.
Available Models
RCP6-GRTR9
- Multi-point positioning capability
- Ideal for flexible automation and variable product handling
EC-GRTR9
- Two-position operation
- Excellent replacement for air grippers and pneumatic cylinders
The GRTR9 platform delivers approximately three times the gripping force and stroke capacity of the previous generation model while maintaining a compact package size.
Features
Mini 3-Finger Electric Gripper Features
Compact Design for Space-Constrained Equipment
The Mini 3-Finger Gripper was designed for installations where space is limited. Its compact dimensions allow mounting directly on robot wrists, Cartesian robots, gantries, and machine tooling.
High Gripping Force
Despite its compact size, the gripper delivers up to:
- 70 N maximum gripping force: This allows secure handling of components while maintaining precise control over gripping pressure.
- Long Stroke Capability: The gripper provides 30 mm total stroke (15 mm per finger). The extended travel accommodates greater variation in part sizes while reducing the need for dedicated tooling.
Programmable Speed Control
Adjust motion characteristics to:
- Improve cycle times
- Reduce impact on delicate parts
- Optimize machine performance
- Improve process consistency
High Positioning Accuracy
Electric actuation enables repeatable positioning performance, helping ensure consistent gripping results across production runs.
Reduced Maintenance
Unlike pneumatic systems that depend on valves, regulators, fittings, and air preparation components, electric grippers reduce common maintenance points and simplify troubleshooting.

Why Choose a Mini 3-Finger Electric Gripper?
Replace Pneumatics with Greater Control
Many automation systems still rely on pneumatic grippers because of their simplicity. However, pneumatic systems typically offer limited control over gripping force and position.
The Mini 3-Finger Gripper provides programmable motion control that allows engineers to optimize handling performance for each product being processed.
Advantages Over Pneumatic Grippers
Precise Force Control
Instead of relying on air pressure adjustments, gripping force can be programmed digitally and adjusted in percentage increments.
- Reduced part damage
- Improved handling of fragile components
- Greater process repeatability
- Faster product changeovers
- Multiple Positions Without Additional Hardware
Improve Throughput and Reduce Changeover Time
Manufacturers increasingly need automation systems capable of handling multiple product variants.
The Mini 3-Finger Gripper helps achieve this by allowing:
- Software-based adjustments
- Product recipe changes
- Programmable gripping force
- Multiple gripping positions
This reduces downtime associated with manual setup changes.
Inspection and Centering Applications
The three-finger design is particularly effective for:
- Round parts
- Cylindrical components
- Optical assemblies
- Precision-machined products
The symmetrical gripping action improves centering accuracy and repeatability.
Lower Total Cost of Ownership
Compared with pneumatic gripping systems, users may achieve:
- Reduced energy consumption
- Fewer maintenance requirements
- Less tooling complexity
- Improved process quality
- Lower scrap rates
Future-Proof Automation
As manufacturers move toward Industry 4.0 initiatives, electric actuators provide greater connectivity, programmability, and data visibility than traditional pneumatic solutions.
The Mini 3-Finger Gripper supports these goals by bringing precision motion control directly to the point of handling.
