LDENC LDEHNC Linked Pneumatic Internal Grippers, Standard and Y18 Extended Thread
Linked pneumatic internal-expansion grippers with standard or Y18 extended mounting threads. Select bare A3/A4/A5 jaws or blue silicone-pad base jaws, with or without an included magnetic switch.
Working medium: air. Aluminum-alloy cylinder bodies are intended for robot-arm and injection-molding handling fixtures. Linked jaws are illustrated gripping internally. Each configuration is sold separately. Supplied use illustrations do not establish a rated lifting capacity; workpieces and machine fixtures are not included.

Dimensions, fitting and source differences
The exact-model original drawings retain all numeric dimensions, lines and product geometry. The source specifies an M5 air inlet with a 6-M5 barb fitting for 6 mm tubing; request and confirm a 4-M5 alternative for 4 mm tubing when needed. The drawings label an M10 mounting thread, with Y18 extended-thread versions. Confirm actual thread pitch and mounting clearance before installation.
LDEHNC Y18 padded base: the SKU table specifies 13-24 mm, while its dimension footer and selection chart state 15-24 mm. The option label follows the SKU table, and the conflicting source range is disclosed here; confirm the actual minimum gripping diameter before ordering. Standard LDEHNC padded base is specified as 15-24 mm.
Control and operating requirements
LDEHNC configurations include a magnetic switch or detection cable as pictured. The source shows a sensor mounting groove and describes checking workpiece pickup through a PLC or relay. Confirm voltage, wiring, connector, output type and controller compatibility for the actual switch. LDENC options have no switch included.
Supplier marketing mentions a 1 kg holding-force reference and more than one million cycles, but supplies no pressure, workpiece, load direction or test basis. These are unverified supplier statements, not a confirmed safe working load or lifetime rating. Confirm grip stability, actual opening, air pressure, mounting and application requirements before use.
