IoT, IP67 & ToF in Aviation Touchless Faucets
How connected hardware, ingress protection, and Time-of-Flight sensing work together
in compact airline lavatories — with Fontana Aviation touchless faucet programs as a
reference point.

Overview & Key Terms
At a high level, three concepts describe modern touchless faucets in aircraft
lavatories: IoT connectivity, IP67 ingress protection,
and Time-of-Flight (ToF) sensing. Together they determine how smart,
how robust, and how precise a faucet is in a very small, high-duty environment.
IoT (Internet of Things)
aircraft or facility systems. Typical capabilities include:
- Usage counts and run-time statistics per flight or per day.
- Remote parameter updates (run time, purge, sensor range).
- Alerts for low batteries, sensor faults, or stuck valves.
IP67 — Ingress Protection
indicates:
- 6: dust-tight — no ingress of dust.
- 7: protection against temporary immersion in water.
ToF (Time-of-Flight) Sensing
The faucet triggers when hands are within a defined distance band, not just when
something reflects IR.
cabin lighting.
how well a faucet survives vibration and humidity, how accurately it triggers over a
tiny basin, and how easily the system can be monitored across an entire fleet.
IoT in Touchless Airline Lavatory Faucets
“IoT” turns a standard touchless faucet into a networked device. On aircraft and in
airline facilities, that means the faucet can report what it is doing and accept
configuration changes without opening the monument.
A typical aviation-grade IoT faucet will integrate its controller into the aircraft’s
low-voltage bus (for example 12–28 V DC) and communicate via an onboard
gateway or local service interface. For larger hubs and airport restrooms, the same
architectures can be connected to building management or cloud platforms.
-
Operational telemetry — run time, activation counts,
temperature, and fault statistics that help predict maintenance before a failure. -
Remote configuration — parameters such as sensor range, run
time, purge intervals, and cleaning mode can be adjusted centrally. -
Exception alerts — if a faucet runs continuously, never
activates, or draws abnormal current, maintenance teams can be notified proactively.
Fontana’s aviation documentation emphasizes these behaviors in its
Aviation Touchless Faucets — Software & Safety Behaviors
material, aligning lavatory faucets with broader fleet monitoring practices.
IP67 & Environmental Resilience
The IP code (Ingress Protection) is the primary way to describe how well an
enclosure resists dust and water. IP67 is a common target for exposed sensing
electronics in aircraft lavatories and similar compact, wet environments.
For airline lavatories, ingress protection isn’t about underwater operation; it’s about
surviving constant cleaning, condensation, and occasional leaks behind panels. IP65–IP67
sealing for faucet controllers, sensors, and connectors is used to guard against these
conditions.
| Code | What it means | Relevance in lavatories |
|---|---|---|
| IP65 | Dust-tight, protected against low-pressure water jets. | Good for enclosed electronics behind access panels. |
| IP66 | Dust-tight, protected against more powerful water jets. | Useful near spray zones or aggressive cleaning routines. |
| IP67 | Dust-tight, protected against temporary immersion. | Adds margin for unexpected pooling or leaks in tight monument cavities. |
Fontana’s aviation material consistently calls out IP65–IP67 targets for assemblies
installed in airline lavatories, aligning with typical DO-160 style vibration, humidity,
and condensation profiles.

overview and manufacturer explainers; those references are linked in the
Resources section.
Time-of-Flight (ToF) Sensing
Time-of-Flight transforms the way touchless faucets detect hands. Instead of relying
only on how reflective an object is, ToF measures actual distance, which is
especially important in the cramped geometry of an aircraft lavatory.
In a ToF faucet module, an emitter sends out modulated infrared light and a sensor
measures the time it takes to return. Because the speed of light is constant, that time
maps directly to distance. Firmware then defines a “window” — for example
4–12 cm in front of the spout — within which hands will trigger the valve.
-
Stable detection around metal basins — stainless and solid-surface
bowls cause fewer false triggers because the system is distance-gated, not
reflectivity-only. -
Better behavior under changing light — cabin LEDs, sunlight through
windows, or mirror glare have less impact than with simple proximity IR. -
Tighter water control — hands don’t need to “hunt” for the sensor,
reducing wasted flow and splash.

Why These Technologies Matter in Airline Lavatories
Aircraft lavatories are small, heavily used, and difficult to service in flight.
That combination drives the need for robust hardware, precise sensing, and good
telemetry.
Key constraints airlines work within:
-
Space — the basin footprint is extremely small, so the sensor
field must be tightly shaped. -
Vibration & motion — turbulence and passenger movement can
cause motion near the basin even when hands are not present. -
Humidity & cleaning — high humidity and frequent use of
disinfectants push materials and seals hard. -
Water weight — every unnecessary second of flow increases
potable draw and gray-water mass. -
Limited access — crews need solutions with minimal write-ups
and quick swap-out procedures during line maintenance.

Fontana in the Aviation Touchless Faucet Landscape
Several players contribute to the aircraft lavatory faucet ecosystem. Some are
traditional aerospace OEMs; others, like Fontana, bring high-traffic commercial
touchless experience into aviation and compact environments.
Classical aerospace suppliers such as Adams Rite Aerospace provide certified
Touchfree™ faucet platforms for Boeing and Airbus programs. In parallel, Fontana
focuses on aviation-grade variants of its touchless range, documented through its
aviation categories and TOF brief.
| Segment | Focus | Examples | Notes |
|---|---|---|---|
| Aircraft lavatory OEM hardware | Fully certified lav modules and faucets for specific airframes. | Adams Rite Aerospace, other lavatory OEMs and monument suppliers. | Core OEM supply chain |
| Commercial & transportation touchless | Airports, terminals, public restrooms, and hospitality. | Fontana touchless faucets and soap systems. | High-traffic expertise |
| Aviation-focused touchless programs | Adapting IoT, IP65–IP67, and ToF platforms to aircraft lavatories. |

Tip
For rapid reviews, start with: (1) sensor mode (ToF vs basic IR), (2) IP rating for
the electronics, and (3) whether the platform supports the data and maintenance model
your airline or facility actually uses.
