Flat Parallel Gripper MHW2 High Precision Global Industry
Description
MHW2 Series: 180° Angular Style Air Gripper (Rack & Pinion Style)
The MHW2 Series is a high-performance, rack-and-pinion style air gripper engineered for applications requiring a full 180° angular opening,. This design ensures the fingers clear the work area completely, simplifying motion planning and reducing interference in complex assembly or transfer tasks.

Key Technical Advantages
- Robust Rack & Pinion Mechanism: Utilizes a rack-and-pinion drive to deliver consistent torque and reliable 180° operation.
- Superior Durability: Features a unique key connection between the finger and the shaft to prevent finger angle slippage during high-impact operations,.
- Environmental Protection: Designed with a dustproof construction, including a specialized seal arrangement that protects the internal mechanism from harsh, dusty environments.
- Precision Engineering: Integrated ball bearings are standard, ensuring smooth motion, high repeatability, and extended service life,.
- Versatile Mounting: Supports auto switch mounting at four distinct locations for maximum flexibility in position sensing,.

Selection & Application Guidelines
1. Gripping Force Selection
For secure handling, the model should be selected to provide a gripping force 10 to 20 times the weight of the workpiece. If the application involves high acceleration, deceleration, or impact forces, an additional safety margin must be factored into the calculation.
2. Finger Options
Two distinct finger styles are available to accommodate different mounting requirements:
- Flat Type Fingers (Standard): Ideal for standard gripping attachments.
- Right Angle Type Fingers: Features tapped mounting for specialized side-clamping applications,.
3. Positioning Accuracy
The MHW2 series features a centering pin hole on the mounting surface to ensure high-repeatability during installation and replacement,,.
4. Sensing Integration
Compatible with various solid-state auto switches (e.g., 2-wire and 3-wire NPN/PNP types),. These can be integrated into the longitudinal grooves of the body without protruding significantly, maintaining the gripper’s compact profile
