Paxini PX-6AX GEN2 Fingertip (PX6AX-GEN2-DP-M2826)

Paxini PX-6AX GEN2 Fingertip (PX6AX-GEN2-DP-M2826)

It belongs to Paxini’s PX-6AX GEN2 family marketed as a professional-grade ITPU multi-dimensional tactile sensing unit—and is intended for dexterous robotic hands, adaptive grippers, and embodied intelligence systems that require tactile feedback beyond traditional force sensors or motor current estimation.

Within the GEN2 lineup, DP-M2826 is classified as a fingertip sensor  and is listed with physical dimensions of 27.9 × 25.7 × 14.4 mm (L×W×H). This form factor is optimized for integration at the distal end of a robotic finger, where contact typically begins and where tactile feedback can most directly influence grasp stability and fine manipulation.

Design and Features

Fingertip-optimized tactile geometry

The DP-M2826 is designed to function as a compact, fingertip-mounted tactile module, offering a balance between small footprint and a meaningful contact surface area. Paxini’s official store listing specifies:

• Model: PX6AX-GEN2-DP-M2826

• Dimensions (L×W×H): 27.9 × 25.7 × 14.4 mm

Fingertip tactile sensors are typically selected when robotic handling requires:

• early contact detection (“first touch”) to prevent collisions,

• pinch grasp stability on small or thin objects,

• fine correction during insertion, alignment, and placement tasks,

• controlled micro-sliding and rolling for repositioning objects inside the grasp.

Multi-dimensional tactile perception outputs

Paxini describes the PX-6AX GEN2 series as supporting multiple tactile output representations (depending on configuration), including:

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

• 3D resultant force (net interaction force),

• 3D torque / moment output (optional).

This is relevant in dexterous robotics because real-world grasping requires more than “pressure magnitude.” Directional loading, contact location shifts, and rotational effects can indicate slip onset, uneven grasping, or object tilt.

Environmental sealing and interference tolerance

PX-6AX GEN2 is positioned for robotics environments that may include dust, splashes, repeated contact, and electromagnetic noise from nearby motors and power electronics. Paxini’s published GEN2 parameters include:

• IP68 dustproof/waterproof protection

• anti-stray magnetic field capability 

Technology and Specifications

Published GEN2 system parameters (platform-level)

Paxini’s official GEN2 specifications describe the PX-6AX GEN2 tactile platform with the following parameters:

• Tactile signal count: 360 channels

• Measurement range:

  • Normal force: 0–25 N

  • Tangential force: ±10 N

• Sampling frequency: 1,000,000 Hz (as listed)

• Maximum output frequency: 1000 Hz

• Spatial resolution: 1 mm

• Accuracy: < 1%FS

• Safety overload: 200%

• Impact overload: 300%

• Operating temperature: 0–50°C

• Lifetime: > 3 million measurements (industrial-grade usage life)

• Ingress protection: IP68

In robotics integration, these specifications support two common goals:

1. High-speed touch feedback for responsive control (grip stabilization, slip suppression).

2. High-density sensing for fine contact interpretation (where, how, and in what direction forces occur).

Model-specific dimensions (DP-M2826)

For the DP-M2826 fingertip module, Paxini lists:

• 27.9 × 25.7 × 14.4 mm (L×W×H)

This size makes it suitable for many robotic finger designs where the fingertip must remain compact while still delivering meaningful tactile data.

Surface coverage and contact behavior

Paxini’s GEN2 documentation also notes tactile surface coverage as including the front face, full front end, and both sides, which is valuable when contact occurs on an edge or side during grasping and manipulation.
Additional platform features such as dynamic temperature compensation and torque sensing support are also described for GEN2.

Applications and Use Cases

Dexterous hands and fingertip manipulation

The DP-M2826 is best suited to robotic systems where the fingertip is the most important sensing point, including:

• dexterous multi-finger hands performing precision grasps,

• adaptive industrial grippers handling mixed objects,

• research platforms studying contact-driven manipulation strategies.

In practice, fingertip touch sensing improves manipulation performance in scenarios where vision alone is unreliable, such as occlusion, glare, low light, or cluttered bins.

Slip detection and grip stabilization

Slip often begins at the fingertip interface through small tangential force shifts and micro-motions. With GEN2’s published tangential measurement range (±10 N) and high-rate output (1000 Hz max output frequency), tactile feedback can support fast grip adjustments before the object is lost.

Assembly, alignment, and insertion tasks

Tactile fingertip sensing is widely used in:

• peg-in-hole style alignment,

• connector insertion and seating verification,

• controlled surface contact during part placement.

In these tasks, contact feedback helps the robot identify the moment of touch, maintain safe forces, and avoid scraping or jamming.

Embodied intelligence and learning-based control

Embodied intelligence workflows frequently combine tactile signals with proprioception and vision for learned policies. Paxini’s GEN2 family is positioned as a dense, high-rate tactile interface that can support data collection and policy learning for robust object handling across shape and material variation.

Advantages / Benefits

High tactile density for richer contact information

With 360 tactile signal channels, GEN2 is designed to provide more informative touch feedback than single-point sensors, supporting better:

• contact localization,

• detection of uneven loading,

• tracking of contact transitions.

Fast output for responsive control loops

GEN2’s maximum output frequency of 1000 Hz can support responsive tactile control behaviors such as slip suppression and gentle placement adjustments.

Industrial durability and safety margin

Published overload tolerance (200% safety overload, 300% impact overload) and long lifetime (>3 million measurements) support repetitive contact cycles typical of robotics trials and production-like testing.

Environmental protection (IP68)

IP68 sealing supports broader operational environments, including systems that face dust exposure and occasional moisture risk.
