Product catalog summary

Overview

The DH Series 2-Jaw Pneumatic Parallel Grippers are designed for industrial automation, featuring self-centering jaws operated by double-acting pneumatic cylinders. They offer configurable stroke lengths, optional springs for normally closed (NC) or normally open (NO) operation, and front fastening via through screws. The grippers use FDA-H1 food-grade grease, making them suitable for hygienic environments.

Key Features

Double-acting pneumatic operation with optional NC or NO springs.
Stroke options: long or short to suit application needs.
Front mounting with through screws for secure installation.
High-efficiency force transmission mechanism for reliable gripping.
Optional magnetic sensors for piston position detection.
Optional inductive sensors (4 mm diameter) for detecting metal parts in jaws; adjustable position; not available on smallest models (DH19, DH22).
FDA-H1 food-grade grease compliant with food industry standards.

Sensors (Optional)

Magnetic sensors: Detect piston magnets; equipped with 3-wire flat cables and LED indicators for easy status monitoring.
Inductive sensors: Detect metal inserts in jaws; adjustable mounting; 2.5 m cables with M8 snap plug connectors; not compatible with smallest models.

Operating and Installation Notes

Compressed air must comply with ISO 8573-1:2010 [7:4:4] to ensure optimal gripper performance and durability.
Integrated sensor grooves and holders simplify installation of magnetic or inductive sensors.
Air ports are clearly marked for opening (A) and closing (C) functions to avoid connection errors.
Front mounting with through screws provides secure and flexible installation options.
Cycle times and air consumption vary by model and stroke; select gripper based on required speed and force.

Additional Mechanical and Pneumatic Details

Mechanical dimensions include detailed mounting hole sizes (M5, M8, M10, M12) and precision bore holes (Ø11, Ø14, Ø16 with h8 tolerance) for accurate integration.
Compressed air ports and pneumatic interfaces are designed for easy connection and maintenance.
Operating pressure ranges from 1.5 to 8 bar depending on model and configuration.
Operating temperature range is 5°C to 100°C, suitable for most industrial environments.

Performance Parameters Summary

Gripping forces at 6 bar vary by model, with opening force per jaw ranging approximately from 75 N to 1350 N and closing force per jaw from 68 N to 1200 N.
Total gripping forces can reach up to 2700 N opening and 2400 N closing for larger models.
Stroke lengths range from 4 mm to 26 mm in the DH series.
Cycle air consumption ranges from 2 cm³ to 97 cm³ per cycle depending on model and stroke.
Repetition accuracy is high at ±0.02 mm, ensuring precise and repeatable gripping.
Weights vary from approximately 87 g to 1770 g depending on model size and stroke.

Recommendations and Best Practices

Maintain compressed air quality per ISO 8573-1:2010 [7:4:4] to prevent premature wear and maintain performance.
Operate within specified pressure and temperature limits to ensure consistent gripping force and avoid damage.
Consider maximum working frequency and air consumption when designing pneumatic supply and control systems.
Utilize sensor integration features for enhanced automation control and feedback.

Summary

The DH Series 2-Jaw Pneumatic Parallel Grippers offer a versatile and reliable solution for industrial automation gripping tasks. With a range of sizes, stroke lengths, and force capabilities, combined with optional sensor integration and hygienic grease, these grippers support precise, repeatable, and clean operation. Detailed mechanical and pneumatic specifications facilitate accurate selection and integration into automated systems.
