More Information

Overview Manuals Selection Installation Service Checks Applications

Features:

  • Gripping motion: Uses two parallel jaws to hold and release a workpiece along a straight path.
  • Pneumatic actuation: Applies double-acting air control across the opening and closing cycle.
  • Application boundary: Requires gripping force to be checked at the actual pressure, jaw length and workpiece position.
DHPS-20-A is used in automated handling where parallel jaw travel supports repeatable pickup, transfer and release of a defined part.

The gripper body and the custom jaw tooling act as one mechanism; tooling mass, gripping-point distance and part geometry all affect the usable holding margin.

Matching DHPS-20-A with Festo part number 1254046 helps maintenance teams retain the intended stroke, mounting and pneumatic interface when replacing an installed unit.

Apter Power supports exact-model document review, quotation, and procurement for the Festo DHPS-20-A Parallel Gripper.

  • Force calculation: use actual pressure, jaw length, part mass, acceleration, and safety factor.
  • Stroke: verify 6.5 mm per jaw covers the full tolerance range.
  • Tooling: confirm jaw mass, geometry, mounting, and center of gravity.
  • Mounting: use the documented interface and keep the gripper body aligned.
  • Air supply: verify pressure, cleanliness, tubing, valves, and exhaust behavior.
  • Sensing: confirm compatible position sensing and cable routing where required.
  • Leak check: inspect fittings, tubing, piston seals, and pressure stability.
  • Motion check: verify equal jaw travel, smooth motion, and absence of collision.
  • Acceptance: test the intended part at controlled speed and record secure hold and release.
  • Part handling: parallel gripping in automated transfer and assembly.
  • Machine tending: supported loads within the calculated force envelope.
  • Maintenance: exact-part replacement where DHPS-20-A or 1254046 is specified.
Description
On an automated handling station, DHPS-20-A provides two-jaw parallel gripping for a workpiece that must be picked, transferred and released on a repeatable path. Its double-acting pneumatic motion supports controlled opening and closing from the machine valve circuit.

The usable grip from DHPS-20-A depends on more than supply pressure. Jaw length, tooling mass, gripping-point distance, part geometry, acceleration and mounting orientation all influence whether the workpiece can be held with an adequate safety margin.

For replacement, DHPS-20-A should be matched with Festo part number 1254046 and the installed mounting, jaw interface, tubing and sensing arrangement. Preserving those interfaces reduces rework and collision risk during restart.

Technical notes
For DHPS-20-A, isolate and vent pneumatic energy, restrain the workpiece, and confirm both jaws are free before service. Match Festo part number 1254046, pressure range, stroke, mounting, jaw interface, sensor provisions, tubing, and application load; stop if the gripper or tooling can release the load unexpectedly.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
A longer custom jaw is planned for DHPS-20-A. Can the existing pressure setting be accepted without recalculation?
No. Recalculate the holding margin using the actual gripping-point distance, pressure, jaw and part mass, acceleration, orientation and the approved safety factor.
The gripper label is damaged but Festo part number 1254046 is readable. Is that enough to identify DHPS-20-A?
Use the part number with the mounting, stroke, jaw interface and sensor arrangement to confirm the identity; do not rely on enclosure appearance alone.
DHPS-20-A reaches the part but one jaw stops early. What should be inspected first?
Check tooling alignment, contamination, mechanical damage, air pressure and flow, tubing restrictions, sensor interference and whether the part enters squarely.
Can DHPS-20-A be operated above 8 bar to compensate for a heavier workpiece?
No. Keep operation within the documented 2 to 8 bar range and redesign the tooling or gripping method if the required force is not available.
What must be secured before technicians remove jaw tooling from DHPS-20-A?
Secure or remove the workpiece, isolate and vent the pneumatic supply, and verify both jaws cannot move before loosening tooling or mounting fasteners.
How should DHPS-20-A be accepted after replacement?
Cycle the gripper first without a part and then with the intended workpiece, confirming full jaw travel, sensing, pressure stability, secure hold, controlled release and collision-free motion.
