5. Integration Options

Finger Options

• Basic Type: Standard parallel motion.
• Flat Type Fingers: Reduced height for narrow-clearance picking.
• Narrow Type: MHQ2 compatible type for streamlined mounting.

Body & Piping Options

• Side Tapped Mounting: Tapped holes for lateral installation.
• Through Holes: Allows mounting in the opening/closing direction.
• End Boss Type (E): Side ported for double/single acting.
• Axial Porting (W/K/M): Available with One-touch fittings for coaxial or standard tubing, or M5 ports for axial air supply.

Clean Room Compatibility

The Series 11- variant is a vacuum-type relief port model (Grade 2) designed to prevent particulates from spreading into clean room environments.
