New Reliable Parallel Gripper FESTO 560200 HGPT-20-A-B-G2 Designed For Demanding Pneumatic Handling Application

The FESTO 560200 HGPT-20-A-B-G2 is a parallel gripper designed for demanding pneumatic handling applications where stable jaw guidance, reliable gripping force, and compact integration are required. Official FESTO product data identifies this model as part of the HGPT series, size 20, with two gripper jaws, double-acting pneumatic drive, parallel gripping function, 4 mm stroke per gripper jaw, and a product weight of 155 g. FESTO also specifies that this version includes gripping force back-up during closing, which is one of the defining functional differences of the -G2 variant.

In practical automation terms, the HGPT-20-A-B-G2 is built for machine builders and industrial users who need a gripper that is more robust than a light-duty miniature gripper, but still compact enough for installation on handling axes, transfer units, assembly stations, and end-effectors. The HGPT family is described by FESTO as a heavy-duty parallel gripper line, and the technical documentation for the series shows that the -G2 versions can be used as grippers with closing gripping force retention, as grippers with supplementary gripping force, or even effectively as single-acting grippers, depending on the application requirement.

Key Technical Data

The core values above come from FESTO’s official product page and datasheet for part number 560200, with the product weight explicitly shown as 155 g on FESTO’s regional product listing. The broader HGPT series catalog also confirms the product family structure and the specific role of -G2 models.

Product Positioning and Functional Role

The HGPT-20-A-B-G2 is not a generic low-cost air gripper. It is part of a gripper range intended for heavier-duty pneumatic gripping tasks, where stable jaw guidance and dependable gripping behavior matter more than minimum purchase cost. FESTO’s HGPT documentation describes the family as heavy-duty parallel grippers, and that positioning is important because it reflects the product’s intended use: repetitive industrial handling, not just simple lab automation or very light pick-and-place work.

Its parallel gripper function means that the two jaws move linearly toward and away from each other, which is the preferred motion style for many industrial parts because it provides symmetrical gripping and predictable force application. This is especially useful in assembly automation, workpiece transfer, packaging, and machine loading tasks where the part needs to remain centered during pickup and release. FESTO’s official data confirms the parallel jaw motion and the presence of two gripper jaws, both of which define the handling behavior of this model.

The Meaning of the G2 Version

The -G2 suffix is one of the most important points for this model. FESTO’s HGPT series documentation states that HGPT-...-G2 versions provide closing gripping force retention. In practical terms, this means the gripper can maintain force in the closing direction even if pneumatic pressure is interrupted, depending on the application setup. The series documentation further explains that the integrated spring in -G2 models allows them to be used as single-acting grippers, as grippers with supplementary gripping force, or as grippers with gripping force retention. That is a meaningful functional advantage in applications where accidental pressure loss could otherwise allow the part to slip or fall.

This matters particularly in vertical handling, in transfer applications with valuable components, or in systems where product security during pressure fluctuation is an engineering concern. Not every application needs this function, but when it is needed, it is a real selection factor. The HGPT-20-A-B-G2 is therefore more than just a standard double-acting gripper; it is a version optimized for applications that benefit from closing-direction grip retention.

Mechanical Characteristics and Precision

Official FESTO data lists the stroke per gripper jaw as 4 mm, which places this size-20 standard variant in a practical middle range for handling medium-small parts. This is enough jaw travel for many industrial gripping tasks without making the body unnecessarily large. The same official technical data lists maximum interchangeability of 0.2 mm, maximum angular jaw backlash of 0.1°, maximum jaw backlash Sz of 0.02 mm, and repetition accuracy of 0.04 mm. These are important numbers because they indicate that the HGPT-20-A-B-G2 is intended for repeatable industrial handling, not only raw gripping force.

In machine-building terms, repeatability matters because grippers do not work in isolation. They interact with feeders, nests, fixtures, conveyors, and other motion modules. If the jaw guidance is loose or inconsistent, gripping quality deteriorates and downstream positioning errors increase. The published backlash and repetition figures suggest that the HGPT-20-A-B-G2 is engineered for stable performance in repeated automation cycles. That is exactly what users expect from a heavy-duty industrial parallel gripper.

Weight and Integration Value

A key requirement in your request is product weight, and for this model FESTO’s official regional product data lists a product weight of 155 g. That figure is useful because it places the gripper clearly in the compact industrial class. At 155 g, the HGPT-20-A-B-G2 is light enough to be mounted on small-to-medium handling axes, compact gantries, and robot end effectors without imposing excessive moving mass, while still indicating a more robust structure than miniature micro-grippers.

This balance is often exactly what machine designers need. A gripper that is too light may lack stiffness or gripping capability for real industrial duty. A gripper that is too heavy increases inertia and can reduce system speed. The HGPT-20-A-B-G2 occupies a useful middle ground: compact, but not fragile; light, but not insubstantial. That conclusion is an engineering interpretation, but it is consistent with the 155 g weight, size 20 format, and heavy-duty series positioning published by FESTO.

Sensing and Installation

FESTO lists the mounting position as optional, which gives flexibility in machine integration, and the HGPT documentation states that position sensing is performed via proximity switch or position sensor. That matters because modern automation equipment almost always needs confirmation of jaw state or actuator position for sequence control and fault handling. A gripper designed with standard sensing compatibility is easier to integrate into PLC-based systems and easier to maintain over time.

The series documentation also shows that HGPT grippers are intended for a wide range of handling and assembly technology combinations, which fits their role as robust pneumatic grippers rather than niche special-purpose devices.

Typical Application Areas

These applications are consistent with the published HGPT family positioning, the parallel gripper function, and the G2 closing gripping force retention feature.

Conclusion

The FESTO 560200 HGPT-20-A-B-G2 is a compact but industrially capable heavy-duty parallel gripper designed for pneumatic handling systems that need stable jaw guidance, repeatable motion, and added holding security during closing. Official FESTO data identifies it as a size 20 gripper with two jaws, double-acting pneumatic drive, 4 mm stroke per gripper jaw, 0.04 mm repetition accuracy, and a product weight of 155 g. The defining advantage of this exact version is the G2 closing gripping force back-up, which makes it especially suitable for applications where part retention during pressure loss or enhanced closing-side force is important. For machine builders, automation integrators, and maintenance users looking for a reliable pneumatic gripper in a compact format, the HGPT-20-A-B-G2 is a technically solid and application-focused choice.
