HF

Product catalog summary

Overview: The document provides technical specifications and details for the HF Series Wide Opening Parallel Hand, specifically models HF-2MS, HF-3MS, HF-4MS, and HF-5MS. These are pneumatic grippers designed for various industrial applications.

Specifications:

Working Pressure: 0.3 to 0.7 MPa
Lubrication: Not required or Turbine Oil Class 1 (ISOVG32)
Ambient Temperature: 5 to 60°C
Total Jaw Stroke: Varies by model
Repeatability: ±0.03 mm
Weight: Varies by model

Key Features:

High grip force to body weight ratio due to efficient design using two cylinders.
Easy mounting with three gripper mounting and two jaw mounting surfaces for flexible layout.
No adjustment needed for multi-purpose applications due to long jaw stroke and parallel clamping.
Optional slide bearing for fixtures requiring locating and parallel accuracy.
Switch slots available for sensing jaw position, with direct switch mount capability for up to two switches.

Parts and Materials:

Body and various components made from aluminum and stainless steel.
Seals and other parts include piston seals, side seals, and rod seals.

Performance Data:

Graphs illustrate grip force in relation to external finger lengths and air pressure for each model.
Optimal grip force ranges are specified for each model, e.g., HF-2MS (40N to 70N), HF-3MS (60N to 170N), HF-4MS (120N to 300N), HF-5MS (200N to 700N).

Ordering Information:

Models are available with various options for sensors and mounting configurations.
Specific symbols and codes are used to denote different configurations and options.

Layout Drawings: Detailed layout drawings are provided for each model, indicating dimensions, mounting holes, and air port locations.
