What a Warehouse Floor Does to Interconnect

Dust and Wash-Down

A mobile robot lives at floor level, where dust, debris and cleaning water collect. Sealed mated interfaces are the difference between a five-year deployment and a recurring service call.

Docked Every Shift

The charge interface is mated and unmated more often than anything else on the machine, and usually without a human aligning it. Gatherability matters more than precision.

Tolerance Stack-Up

Chassis, mounting plate and PCB tolerances all accumulate at the connector. Floating board-to-board absorbs that stack instead of transferring it into the contacts.

Part of a Fleet

One robot is a machine; fifty are a network. Industrial Ethernet back to fleet control has to stay clean while the vehicle moves through a building full of interference.

Duty Cycle Is the Design Constraint

Autonomous mobile robots and automated guided vehicles carry warehouse logistics, manufacturing flow and facility automation. They depend on high-efficiency batteries, intelligent motor drives and sensor arrays precise enough to navigate a floor that changes through the day.

Unlike a humanoid, an AMR is not fighting for millimetres inside a limb. Its problem is repetition and environment. It runs multi-shift, docks to charge on a cycle no operator supervises, absorbs vibration through a rigid chassis, and does all of it in a space being swept, washed and driven through.

Amphenol supplies rugged, compact interconnect across every subsystem of the mobile robot — controllers, charging, battery management, LiDAR and camera-based vision — with the sealing and latching that environment demands.

Minitek® Pwr 3.0 BMI

Blind-mate interface for the charge dock

A 3 mm blind-mate power system carrying up to 12 A per circuit. The BMI geometry gathers over ±2.54 mm of misalignment, which is what makes it suitable for an interface the robot has to find by itself, on a dock, several times a day, with no one guiding it in.

Current: up to 12 A per circuit
Gatherability: ±2.54 mm blind mate interface
Circuits: 4 to 24 dual row, right-angle and vertical
Hot plug: supports FMLB for hot-plug applications
Protection: fully isolated terminals, scoop-proof housing
Polarisation: keyed geometry prevents mismating
Materials: UL 94 V-0 LCP, RoHS and lead-free

FloatCombo™ 0.50mm with Power Pin

Floating hybrid board-to-board for stacked controllers

Floating board-to-board that absorbs accumulated chassis and board tolerance rather than passing it into the contacts, combining four independent power pins with high-speed signal. Amphenol names robotics directly among its target applications alongside automotive ADAS and BMS.

Float: X/Y ±0.80 mm, Z ±0.60 mm (stack height under 15 mm)
Power: 5 A per pin across 4 independent power contacts
Signal: 20 to 140 contacts, up to 16 Gb/s (PCIe® 4.0)
Stack height: 8.0 mm to 30.0 mm
Vibration: USCAR-2 T3V2 qualified
Temperature: −55 °C to +125 °C including T-rise
Assembly: anti-fool design with guides for blind mating

Featured Products — Networking and Sensing

ix Industrial™ IP6X Push-Pull, NDH Series

Sealed Cat6A Ethernet for fleet networking

Cat6A industrial Ethernet on the IEC 61076-3-124 interface, sealed to IP65, IP66 and IP67 and UV resistant. A two-stage push-pull latch keeps the link mated through vibration, and the sealed plug still mates with standard IP20 ix Industrial receptacles, so one interface covers inside and outside the chassis.

Standard: IEC 61076-3-124 ix Industrial™ interface
Speed: Cat6A Ethernet
Sealing: IP65, IP66 and IP67; UV resistant
Latch: two-stage locking, impact and vibration resistant
Compatibility: mates with standard IP20 receptacles
Form factor: small and lightweight, vertical or horizontal
Termination: field-terminable plug kits or factory assemblies

Single Pair Ethernet (SPE) IP20

One pair for data and power to every sensor

IEC 63171-6 Ethernet to LiDAR, cameras and actuators over a single pair, with PoDL carrying power on the same conductors. Fewer, thinner runs inside the chassis, and no protocol conversion gateway between the sensor and the navigation stack.

Speed: 1 Gb/s to 40 m, 10 Mb/s to 1 km
Power: 4 A rating supporting PoDL
Shielding: 360° through the mated pair for EMI immunity
Latch: thumb-actuated metal latch prevents accidental unmating
Mounting: right-angle and vertical PCB receptacles with board-locks
Termination: field-terminable IDC plugs
Standard: IEC 63171-6, cross-vendor compatible

BrightConnX™ MRD Series IP67 Circular

Sealed circular for external I/O and payload

IP67 sealed circular connectors and cable assemblies for anything that leaves the enclosure — payload power, external sensors, safety devices. A quick- release metal thumb latch gives positive locking that still unmates by hand, and finished assemblies ship in 1 m and 3 m standard lengths.

Sealing: IP67 in the mated condition
Current: up to 10 A
Positions: 2 to 9, across Size A and Size B shells
Housings: all-plastic, or metal locking bodies for durability
Latch: quick-release metal thumb latch
Assemblies: 1 m and 3 m standard, double-ended or pigtail
Options: panel or cable mount, finger-proof, dust caps

Frequently Asked Questions

It depends where the interface sits. Inside a closed chassis, IP20 parts such as SPE IP20 or standard ix Industrial receptacles are usually enough. Anything on an external face — payload connections, charge contacts, exposed sensors — wants IP67, which protects against dust and water including immersion while mated. The ix Industrial IP6X NDH series is useful precisely because its sealed plug still mates with standard IP20 receptacles, so one pinout covers both.

Minitek® Pwr 3.0 BMI gathers over ±2.54 mm through its blind mate interface, and the same BMI option is available on Minitek® Pwr 4.2. That figure is the one to design the dock mechanics against: it sets how accurately the robot has to position itself before the connector takes over and finds its own alignment.

Because chassis, bracket and PCB tolerances all add up at the connector, and a rigid part transfers that stack straight into the contacts. FloatCombo™ absorbs ±0.80 mm in X and Y and ±0.60 mm in Z at stack heights under 15 mm, which lets a controller board mate to a backplane reliably on an automated line rather than needing hand alignment.

SPE carries Ethernet over one pair instead of two or four, at 1 Gb/s up to 40 m or 10 Mb/s up to 1 km, and PoDL puts up to 4 A of power on the same conductors. On a mobile robot that means each LiDAR or camera needs one thin run rather than separate data and power cables — less mass, less volume in the cable chase, and no protocol conversion gateway in between.

No — in Minitek® Pwr 3.0 BMI it stands for Blind Mate Interface. It is a mechanical feature describing the connector’s ability to self-align during mating. Battery management sense and balance lines are a separate part of the design, covered by the fine-pitch wire-to-board ranges.

Yes. BrightConnX™ MRD assemblies ship in 1 m and 3 m standard lengths in every insert arrangement, double-ended or as a single-ended pigtail, with custom lengths available from the factory. The ix Industrial and SPE ranges offer both factory-certified assemblies and field-terminable kits, which is often the better answer for service spares.

FloatCombo™ is USCAR-2 T3V2 qualified and rated from −55 °C to +125 °C including temperature rise. The ix Industrial IP6X latch is a two-stage design specified as impact and vibration resistant, and the BrightConnX™ MRD circular housing is described as shock and impact resistant for industrial use.
