What Is the SMC MHZL2-25D Pneumatic Gripper?

The SMC MHZL2-25D is a compact pneumatic parallel gripper from the SMC MHZ series. It uses compressed air to open and close two parallel jaws for gripping, holding, and releasing components in automated pick-and-place, assembly, and material handling applications. The "25" designates the bore size (25mm), and the "D" indicates a double-acting configuration for positive control in both opening and closing directions — essential in robotic end-of-arm tooling and fixed automation workstations.

In short: An SMC 25mm bore pneumatic parallel gripper — picks, holds, and releases parts on robotic arms and automated assembly stations using compressed air for rapid, repeatable gripping cycles.

Key Features

1. Double-Acting (D) Operation

What it means: Air pressure drives both the open and close strokes — spring return is not relied upon.
Why it matters: Consistent gripping force in both directions, faster cycle times, and the ability to hold position against external forces.
Result: Reliable part handling without the risk of spring fatigue or inconsistent spring-return gripping force.

2. 25mm Bore Compact Body

What it means: The 25mm pneumatic cylinder diameter balances grip force with compact dimensions for tight spaces.
Why it matters: End-of-arm tooling must be as light and compact as possible — every gram of gripper mass reduces robot payload capacity.
Result: Good gripping force-to-weight ratio for small to medium component handling.

3. Parallel Jaw Motion

What it means: Both jaws move symmetrically, centering the gripped part regardless of its width.
Why it matters: The part centerline remains constant — critical for precision placement in assembly and insertion operations.
Result: Accurate, repeatable part positioning without the offset correction needed with single-moving-jaw grippers.

Key Specifications

Typical Applications

• Electronics Assembly: Gripping small PCB assemblies, connectors, and components for insertion and placement in automated electronics manufacturing.
• Laboratory Automation: Handling vials, tubes, and microplates in automated liquid handling and sample preparation workstations.
• Consumer Product Assembly: Picking and placing small plastic and metal components in high-speed consumer goods assembly lines.
• Packaging Pick-and-Place: Transferring products into blister packs, cartons, and trays on automated packaging lines.

Frequently Asked Questions

"What gripping force can I expect from the 25mm bore?"

Gripping force depends on operating air pressure — at the typical 0.5-0.6 MPa (72-87 PSI), a 25mm bore gripper produces approximately 30-50N of grip force per jaw at the fingertips. The exact force varies with jaw length (finger design) — longer jaws reduce force due to leverage. Use SMC sizing software or the datasheet force graphs for your specific jaw geometry.

"Can I use this gripper with a vacuum instead of compressed air?"

No. Pneumatic grippers require positive compressed air pressure to operate — vacuum will not generate the force needed to actuate the piston. The air supply should be clean, dry, and filtered (5-micron filter recommended) with appropriate lubrication if required by the application duty cycle. Most SMC grippers are factory-lubricated and do not require continuous oil-mist lubrication.

"What sensors are available for jaw position detection?"

SMC MHZ series grippers accept compatible magnetic auto-switches (reed or solid-state) mounted in the sensor grooves on the gripper body. These detect the jaw open or closed position for PLC feedback. Switches are typically sold separately — verify the correct SMC switch model (D-M9 series or compatible) for the MHZL2 body.
