Paxini PX-6AX GEN2 Fingertip Pad (PX6AX-GEN2-IP-L5325)

Paxini PX-6AX GEN2 Fingertip Pad (PX6AX-GEN2-IP-L5325)

It belongs to Paxini’s PX-6AX GEN2 tactile sensor family—marketed as a professional-grade tactile perception platform supporting multi-dimensional measurement outputs and dense tactile channels for dexterous manipulation.

Unlike “fingertip” modules that emphasize a compact terminal contact point, a fingertip pad sensor is optimized for broader, more stable contact across the finger’s pad area, which is often the primary load-bearing surface during sustained grasping. For the PX6AX-GEN2-IP-L5325, published dimensions are 52.5 × 24.7 × 9.3 mm (L×W×H), placing it among the larger GEN2 pad-form tactile modules intended to provide a wider contact surface for contact-rich robotic handling.

Design and Features

Fingertip pad form factor for stable, surface-based grasping

The PX6AX-GEN2-IP-L5325 is categorized as a fingertip pad tactile sensor. In many robotic hands, the pad region provides the most reliable, repeatable contact during:

• grasping larger objects,

• holding items for extended periods,

• pushing and pressing actions,

• controlled sliding or repositioning within the hand.

The L5325 geometry supports these interactions by offering a longer tactile footprint while maintaining a relatively low profile thickness. Paxini-compatible listings specify its size as:

• 52.5 × 24.7 × 9.3 mm (L×W×H)

Multi-dimensional tactile perception outputs

Paxini’s PX-6AX GEN2 specification page describes tactile outputs (configuration-dependent) including:

• 3D distributed force arrays (spatial pressure/force distribution),

• 3D resultant force (net contact force),

• 3D torque/moment (optional).

For fingertip pad applications, distributed force mapping is especially valuable because pad contacts often involve:

• multi-point pressure patterns,

• shifting load distributions as the object tilts,

• partial contact during rolling or pivoting,

• continuous contact during pushing.

Environmental sealing and interference tolerance

PX-6AX GEN2 sensors are positioned for real-world robotics usage with published features such as:

• IP68 dustproof/waterproof protection

• anti-stray magnetic field capability

• long cycle durability with over 3 million measurement cycles (as stated in GEN2 parameters)

These characteristics are commonly associated with deployments where the tactile sensor must withstand repetitive contact and operate near motors, drives, and industrial electronics.

Technology and Specifications

Model-specific mechanical dimensions (IP-L5325)

The PX6AX-GEN2-IP-L5325 fingertip pad sensor is listed with:

• Dimensions (L×W×H): 52.5 × 24.7 × 9.3 mm

The comparatively wider sensing area supports more stable contact with flatter surfaces and improves tactile feedback during continuous grasps.

GEN2 platform performance parameters

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

• 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

In tactile manipulation, the combination of normal + tangential force sensing is often used to detect micro-slip, evaluate grasp friction, and regulate grip force with minimal damage to objects.

Surface coverage and compensation features

Paxini also describes GEN2 as supporting:

• surface coverage across front face, full front end, and both sides,

• dynamic temperature sensing compensation,

• torque perception support (“supports arbitrary rotation axis perception”), depending on configuration.

For fingertip pad sensors, broad surface coverage is particularly useful because pad contact can occur off-center or along edges when manipulating irregular shapes.

Applications and Use Cases

Dexterous robotic hands for stable “pad-first” grasps

Many robotic grasp strategies rely on the fingertip pad, not only the fingertip point. The PX6AX-GEN2-IP-L5325 is well-suited to:

• power grasps (holding with larger contact patches),

• secure transport (reducing slip while moving objects),

• compliant holding of fragile items through tactile feedback loops.

With a larger sensing area, tactile pad sensors can make it easier to maintain stable pressure distributions and reduce localized stress on delicate surfaces.

Slip detection and friction-aware grasping

Slip detection is often tied to tangential force changes and evolving contact distribution. GEN2’s published tangential force range (±10 N) and output frequency (1000 Hz) support rapid detection of unstable conditions, enabling the controller to:

• increase grip force slightly,

• adjust finger posture,

• re-center contact to stabilize the object.

This is important in object handling where friction is uncertain—such as glossy packaging, coated parts, or smooth plastic housings.

Controlled pushing, pressing, and surface interaction

A fingertip pad tactile sensor is commonly used in:

• pushing objects into fixtures or trays,

• pressing buttons, latches, or compliant interfaces,

• sliding along a surface to locate edges or alignment features.

Pad contact sensing can reduce the risk of over-pressing and can confirm when the target surface has been reached.

Contact-rich learning in embodied intelligence

Tactile sensing is frequently integrated into embodied intelligence pipelines where robots learn manipulation behaviors from multimodal signals. A pad sensor provides stable, repeatable contact feedback that supports:

• grasp stability learning across object variations,

• continuous-contact manipulation (pushing and rolling),

• exploration tasks when vision is occluded.

Advantages / Benefits

Larger sensing area for higher grasp stability

The 52.5 mm length and 24.7 mm width provide a broader contact region compared with compact fingertip-only sensors. This can improve:

• stability under load,

• detection of distributed pressure patterns,

• robustness when grasping flatter or larger objects.

Dense tactile channels (360) for informative contact mapping

GEN2’s 360 tactile signals support richer perception than single-point pressure sensors, enabling contact localization and monitoring of pressure distribution changes over time.

High-rate tactile output for responsive control

A 1000 Hz maximum output frequency can support closed-loop tactile control behaviors where the robot continuously adapts to small contact changes.

Durability and overload headroom

GEN2’s published overload tolerance (200% safety overload, 300% impact overload) and durability claim (>3 million measurement cycles) support repeated contact tasks in testing and deployment environments.

IP68 protection for real-world environments

IP68 sealing reduces exposure-related failures from dust and water ingress, improving operational reliability in industrial or field robotics.
