SMC 11-MDHR3-10E-M9P | Clean Room 3-Finger Rotary Actuated Air Gripper MHR3 Series Size 10 E-Type Auto-Switch

The SMC 11-MDHR3-10E-M9P is a clean room specification 3-finger rotary actuated air gripper from the MHR3 series. Part number decoded: MDHR3 = MHR3 series double acting 3-finger, 10 = size 10 (10mm jaw opening), E = E-type finger style, M9P = pre-mounted auto-switch (NPN solid-state). The MHR3 extends the MHR2 rotary gripping concept from two fingers to three, providing 120-degree triangulated gripping for superior cylindrical part handling.

Why choose 3-finger over 2-finger gripping? Three fingers provide self-centering triangulated contact that automatically centers cylindrical, spherical, and hexagonal workpieces regardless of initial orientation. Two-finger grippers can grip these parts but may allow the workpiece to rotate between the jaws. The 120-degree spacing of the MHR3's three fingers creates three-point contact that positively locates the workpiece center axis. This is essential for clean room applications handling precision pins, optical fiber ferrules, lens assemblies, vials, and other cylindrical components where angular orientation and centering accuracy matter.

The MDHR3-10E-M9P provides 3-finger rotary gripping with NPN auto-switch at size 10. For 2-finger rotary gripping at the same size, the MDHR2-10E provides the two-jaw alternative. For larger 3-finger capacity, consult SMC for MHR3 size availability. For parallel 3-finger gripping without rotary action, the MHS3 series provides linear 3-jaw grippers. The E-type finger geometry is optimized for specific workpiece shapes. Clean series (11-) fluorine grease. RoHS compliant.
