SMC MHY2-25D Finger Double Action Pneumatic Gripper
1. Product Overview
The SMC MHY2-25D is an angular-style double-action pneumatic gripper from SMC’s MHY2 series, engineered for precise gripping of small to medium-sized cylindrical, spherical, or irregular workpieces in industrial automation systems. It features a 25 mm bore diameter and a scissor-type linkage mechanism that drives two fingers to open and close in a synchronous angular motion, with a maximum opening stroke of 28 mm. This gripper is optimized for applications such as electronic component handling, small-part assembly, and robotic pick-and-place tasks where space is limited and flexible workpiece adaptation is required. The double-acting design enables independent control of gripping and releasing actions via compressed air, while compatibility with magnetic switches supports real-time position feedback for seamless integration into PLC-controlled production lines. Its durable, corrosion-resistant construction ensures long service life and reliable performance under standard industrial operating conditions.
2. Main Functions
| Function | Detailed Description |
|---|---|
| Angular Synchronous Gripping | Scissor-linkage mechanism drives two fingers to open/close in a symmetric angular motion, adapting to round, cylindrical, or irregularly shaped workpieces without requiring custom jaw pads. |
| Double-Acting Bidirectional Control | Uses compressed air for both gripping (finger closing) and releasing (finger opening) actions, eliminating return springs and enabling adjustable gripping force via pressure regulation. |
| Magnetic Position Feedback | A built-in magnetic ring in the piston allows installation of magnetic proximity sensors, providing open/closed status signals for system synchronization and safety interlocks. |
| Space-Saving Installation | Compact, lightweight design with centralized air ports supports direct mounting on robotic end-effectors, linear slides, or small fixtures, optimizing layout in dense automation setups. |
| Versatile Workpiece Compatibility | Accommodates workpieces with diameters ranging from 0 to 28 mm (maximum opening) via the angular finger motion, suitable for both internal and external gripping of small components. |
| High Repeatability | Precision-machined linkage and guide components ensure consistent finger positioning accuracy, meeting the requirements of high-precision assembly and inspection tasks. |
3. Technical Features
- Scissor-Linkage Angular Design: The scissor mechanism converts linear piston motion into angular finger movement, providing a wide gripping range while maintaining compact overall dimensions.
- Durable Corrosion-Resistant Construction: Main body and finger links are made of hard-anodized aluminum alloy; piston rods and fasteners are crafted from SUS304 stainless steel for wear and corrosion resistance.
- Adjustable Gripping Force: Gripping force ranges from 80 N to 450 N (at 0.2–0.7 MPa operating pressure), allowing customization for delicate or rigid workpieces without damage risk.
- Broad Operating Conditions: Functions reliably at an air pressure range of 0.2–0.7 MPa and an ambient temperature range of -10°C to 60°C, compatible with filtered compressed air (particle size ≤5 μm).
- Sensor Integration Flexibility: Compatible with SMC D-M9 series magnetic switches, which can be mounted on the gripper’s side grooves without additional brackets, simplifying setup and maintenance.
- Maintenance-Free Operation: Sealed internal components and pre-lubricated linkages eliminate the need for regular lubrication, reducing downtime and operational costs.
- RoHS Compliance: Meets international environmental standards, free of restricted hazardous substances, making it suitable for eco-friendly manufacturing facilities.
