MHY2-20D Gripper

Product Positioning
The MHY2-20D is a 180° pivot opening type cam gripper from the SMC MHY2 series, featuring double-acting design. This series is characterized by its lightweight and compact cam mechanism, unique wide-angle opening (180°), and excellent foreign matter resistance. It is specifically designed for automation applications requiring simplified pick-and-place actions and space savings, and is widely used in fields such as electronic component assembly, small parts handling, packaging sorting, and medical devices.

Core Highlights: 180° Wide Angle, Lightweight Cam Structure, Foreign Matter Resistance

• 180° Opening/Closing Type, Simplifies Pick-and-Place Actions: Achieves a wide 180° opening/closing angle (open side 180°, close side -3°) using a unique cam mechanism.
  • This characteristic significantly simplifies workpiece picking and placing actions. In some applications, it eliminates the need for complex robot arm trajectory planning, making it easy to grasp and release workpieces and improving production efficiency.
• Cam Drive, Lightweight and Compact: Utilizes a cam drive mechanism, resulting in a compact structure that achieves lightweight and small bore size.
  • The MHY2-20D weighs only approx. 320g, significantly reducing the load inertia on the end effector, contributing to high-speed, high-precision motion control.
• Built-in Magnet, Smart Control: A built-in magnet allows for easy selection of auto switches, which can be mounted in 4 positions for non-contact detection and feedback of the open/close positions.
  • Note: This model MHY2-20D (standard) comes without auto switches (i.e., No auto switch (built-in magnet)); they must be selected separately (e.g., -M9BL, -M9BW).
• Double-Acting Drive, Clear Gripping Moment: Employs double-acting design where compressed air controls both opening and closing actions.
  • Bore size Φ20mm, gripping moment at 0.5MPa is 1.10 N·m, sufficient for stable gripping of small to medium-sized workpieces.
• Foreign Matter Resistance Design, Strong Adaptability: The finger opening/closing parts are specially designed to effectively prevent the ingress of fine particles, enhancing reliability and life in dusty or contaminated environments.
• Wide Operating Condition Adaptability, Maintenance-Free Lubrication: Operating pressure range 0.1~0.6 MPa, max. operating pressure 0.6 MPa, min. operating pressure 0.1 MPa.
  • Ambient/Fluid temperature -10~60°C.
  • Port size M5×0.8.
  • Non-lube type, pre-lubricated at factory, no additional oil supply needed for long-term operation, reducing maintenance costs.

Summary: The Lightweight, Compact Choice for 180° Wide-Angle Pick-and-Place
The MHY2-20D Cam Gripper perfectly addresses the core requirement in automated gripping for “wide-angle action that is also compact, reliable, and durable” through its three key technological advantages: the 180° wide-angle opening/closing design simplifying pick-and-place actions, the cam drive achieving lightweight and compactness, and the foreign matter resistance design enhancing environmental adaptability. Its 1.10 N·m gripping moment ensures stable gripping of small to medium workpieces, the built-in magnet reserves intelligent control capability, and the M5×0.8 standard port simplifies system integration. Choosing the MHY2-20D means equipping your automated equipment with a wide-angle, lightweight, reliable, and durable “pick-and-place arm”—an ideal choice for achieving efficient and precise gripping operations in the electronics, packaging, and medical fields.
