Paxini PX-6AX GEN2 Fingertip (PX6AX-GEN2-DP-S2716)

Paxini PX-6AX GEN2 Fingertip (PX6AX-GEN2-DP-S2716)

It is part of the Paxini PX-6AX GEN2 tactile sensor family often described as an ITPU (Integrated Tactile Perception Unit) platform designed to support dexterous robotic hands, adaptive grippers, and embodied intelligence systems that require tactile feedback beyond simple pressure detection.

The DP-S2716 is categorized as a fingertip sensor  and is listed with compact dimensions of 27 × 16.7 × 13 mm (L×W×H), making it a smaller-format option within the GEN2 fingertip lineup.
In practical robotics design, compact fingertip tactile sensors are commonly used where the finger geometry must remain slim while still providing high-value touch information for grasp reliability, slip detection, and gentle handling.

Design and Features

Compact fingertip geometry for dexterous integration

The defining feature of PX6AX-GEN2-DP-S2716 is its small fingertip form factor, which supports installation on robotic fingers with limited surface area or tight spacing between digits. Paxini lists the DP-S2716 size as:

• 27 × 16.7 × 13 mm (L×W×H)

This compact geometry can be advantageous in robotic hands that require:

• narrow fingertip profiles for reaching into confined spaces,

• multi-finger coordination where fingertips must avoid interfering with each other,

• precision pinch grasps on small objects such as components, fasteners, or tools.

Multi-dimensional tactile perception (force + contact behavior)

The PX-6AX GEN2 platform is presented as a multi-dimensional tactile system capable of output representations such as:

• 3D distributed force arrays (contact distribution across the surface),

• 3D resultant force (net contact force),

• 3D torque / moment (optional).

This matters for robotic manipulation because grasp success depends not only on “how much force,” but also:

• where contact is happening,

• whether contact is shifting (rolling/tilting),

• whether tangential forces are increasing (often associated with slip risk).

Environmental protection and stable sensing in real deployments

Paxini positions GEN2 as suitable for robotics environments that include dust exposure, repeated contact cycles, and real-world handling conditions. GEN2 features include:

• IP68 dustproof/waterproof protection

• anti-stray magnetic field capability

• a long service-life claim of over 3 million measurement cycles

Technology and Specifications

Model-specific dimensions (DP-S2716)

Paxini’s official listing identifies PX6AX-GEN2-DP-S2716 as a fingertip variant with:

• Dimensions (L×W×H): 27 × 16.7 × 13 mm

This positions it as a more compact fingertip option compared with larger GEN2 fingertip variants (e.g., DP-L3530 and DP-M2826), enabling tactile sensing in slimmer finger designs.

GEN2 platform-level performance parameters

Paxini’s official GEN2 specification page lists the following product parameters for PX-6AX GEN2 tactile sensing:

• Tactile signal count: 360 channels

• Measurement range:

  • Normal force: 0–25 N

  • Tangential force: ±10 N

• Operating temperature: 0–50°C

• Measurement sampling frequency: 1,000,000 Hz (as listed)

• Maximum output frequency: 1000 Hz

• Spatial resolution: 1 mm

• Safety overload: 200%

• Impact overload: 300%

• Accuracy: < 1%FS

• Ingress protection: IP68

Surface coverage and temperature compensation behavior

Paxini also describes GEN2 as covering contact on the front face, full front end, and both sides, which is relevant for fingertip interaction where objects often touch edges rather than a single flat surface.
GEN2 additionally lists features such as dynamic temperature sensing compensation, supporting more consistent tactile interpretation across varying conditions.

Applications and Use Cases

Dexterous robotic hands and multi-finger grasping

Fingertip tactile sensors are widely used in dexterous robotic hands because the fingertip is where touch begins and where control decisions can most directly prevent grasp failure. The DP-S2716 is suited to:

• precision pinch grasps on small objects,

• multi-finger manipulation where compactness matters,

• regrasping (micro-adjustments to improve stability),

• gentle handling that requires touch-confirmation rather than trial-and-error force ramps.

Slip detection and stability control in uncertain friction conditions

Slip onset frequently appears as changing tangential forces and shifting contact distribution. With GEN2’s published tangential range (±10 N) and maximum output frequency (1000 Hz), tactile-based strategies can support grip stabilization when handling:

• smooth or glossy surfaces,

• coated packaging,

• irregular objects with shifting centers of mass.

Assembly, insertion, and alignment tasks

In structured manipulation—such as fitting, aligning, or inserting parts—tactile feedback enables:

• confirming first contact,

• maintaining safe force while searching for alignment,

• detecting jamming or misalignment early,

• verifying seating and placement stability.

Compact fingertip sensors such as DP-S2716 are often useful in tight assemblies where the finger must fit into narrow clearances.

Embodied intelligence and tactile dataset collection

Embodied intelligence workflows frequently combine vision + proprioception + touch to learn robust manipulation policies. Paxini’s GEN2 family is positioned as a high-density tactile input that can support training data for contact-aware policies, especially when vision is uncertain (occlusion, glare, low-light).

Advantages / Benefits

Space-efficient fingertip tactile sensing

With a listed size of 27 × 16.7 × 13 mm, DP-S2716 is one of the more compact GEN2 fingertip variants, supporting tactile integration even in slim finger designs.

High tactile signal density (360 channels)

GEN2’s 360 tactile signals can provide richer contact interpretation than single-point sensors, helping identify uneven loading, shifting contact zones, and early instability.

High-rate output for real-time control

A 1000 Hz maximum output frequency can support fast closed-loop behaviors such as grip correction and safer contact transitions.

Durability and protection for repeated-contact use

GEN2’s stated IP68 sealing, 200% safety overload, 300% impact overload, and >3 million measurement cycles support repeated tactile interaction in testing and deployment conditions.
