Product catalog summary

Introduction
The HF3DP series is a high-precision three-finger parallel gripper designed for industrial applications. It features a double-acting type operation with air as the media. The gripper is available in three bore sizes: 16mm, 20mm, and 25mm, each with specific operating pressure ranges and proof pressures.

Specifications
The gripper operates within a pressure range of 0.15 to 0.7 MPa and can withstand a proof pressure of up to 1.05 MPa. It functions optimally within a temperature range of 0 to 60°C and does not require lubrication, although mechanical sliding parts do. The repeatability is ±0.01 mm, and centering accuracy is ±0.05 mm.

Materials and Construction
The gripper is constructed from materials such as aluminum alloy, stainless steel, carbon steel, and synthetic rubber. Key components include the body, head cover, piston rod, magnet, and various seals.

Order Codes
Order codes are structured based on bore size, operation type, and sensor switch type. Sensor switches are available in both horizontal and vertical lead wire configurations.

Gripping Forces and Moments
The effective gripping force varies with the grip point length and operating pressure. The document provides detailed graphs illustrating these relationships for each model.

Handling Instructions and Precautions
To ensure optimal performance, fingers should be designed to be as short and light as possible. A speed controller is recommended to minimize impact forces. Shock absorbers should be used to prevent sudden stops that could dislodge workpieces.

Sensor Switches
Sensor switches are available in solid-state types with indicator lamps. They can be mounted using a flat blade screwdriver, and the tightening torque should be carefully controlled.

Dimensions
Detailed dimensions are provided for each model, including specifications for mounting threads and locating holes.

Conclusion
The HF3DP series grippers are designed for precision and reliability in industrial settings, with a focus on minimizing wear and maximizing gripping accuracy.

When attaching fingers on the levers, design them as short and as light as possible. If the fingers are longer and heavier, the impact force when opening and closing will increase and cause a decrease in the gripping accuracy and/or wear and damage to the sliding portion. Also, to prevent the workpiece from falling down or being damaged, and to reduce the metal contact noise when gripping, plastic or rubber materials should be attached to the fingers at the...

• Open/closed stroke differential (Open/closed angle differential) The stroke differential (angle differential) between the point where the lever on one side moves and turns the switch ON and the point where the switch is turned OFF as the lever travels in the opposite direction. • Operating position repeatability When the lever on one side moves in the same direction, operating position repeatability is defined as the range of the deviation of the position where the switch is turned ON or turned OFF. • Three-finger type linear guide specification (air hands) Insert the switch into the switch...
