Datasheet
FEATURES
DESCRIPTION
Honeywell has over 30 years’ experience designing and
delivering accurate and reliable proximity sensors that are
currently used in a variety of military and commercial aircraft.
Honeywell’s patented IHM Series Aerospace Proximity Sensors
are configurable, non-contact devices designed to sense
the presence or absence of a target in harsh-duty aircraft
applications. The IHM Series provides on/off output, and can be
configured with an optional health monitoring output to the host
system. The technology Honeywell uses in the IHM Series is
considered an improvement on traditional ECKO (Eddy Current
Killed Oscillator) topology that previously had been the standard
in aerospace applications. The IHM Series helps to reduce
downtime and maintenance costs due to a unique circuit that
can detect any internal failures and display a fault output instead
of a false positive or false negative.
VALUE TO CUSTOMERS
• Enhanced vibration and EMI specifications help to increase
revenue (flight hours) and reduce cost to serve (system
maintenance)
• Hermetic sealing helps increase revenue (flight hours), reduce
cost to serve (maintenance), & reduce cost of goods (spares)
• Platform approach helps to increase revenue (speed
to market) and reduce cost to serve (lower engineering
investment)
• Health monitoring helps to increase revenue (flight hours),
reduce cost to serve (maintenance), and reduce cost of goods
(spares)
• Supplier stability helps to reduce cost to serve (troubleshoot
with original supplier)
• Current install base helps to reduce cost to serve (proven
performance and MTBF)
Sensing and Productivity Solutions
• Industry-leading indirect lightning and dielectric ruggedness:
Meets the increased requirements of today’s composite
aircraft and most challenging applications including landing
gear, thrust reversers, and flight controls
• Superior vibration ruggedness: Capable of withstanding
extremely high vibration applications
• Environmentally rugged: Fully hermetic packages provide
long-term reliability in very harsh environments by eliminating
the potential for contamination of the sensor from the
application environment. In addition, Honeywell has developed
an innovative method to hermetically seal wire-lead (pigtail)
configurations
• Integral Health Monitoring Capability: Optional third output
state to indicate the health of the sensor (whether it is healthy
or failed). Reduces maintenance time, reduces delayed flights,
and lowers overall maintenance cost across the life of the
aircraft
• Non-contact design: Utilizes non-contact technology to
sense the presence or absence of a target regardless of the
dirty, harsh environment in which it is placed, eliminating
mechanical failure mechanisms, reducing wear, minimizing
downtime, increasing durability, and increasing reliability
POTENTIAL APPLICATIONS
• Cargo loading latch detection (palet locked)
• Doors (open/closed position, locked status)
• Evacuation slide door-lock mechanism
• Flight controls (flap/slat, spoilers)
• Landing gear (uplock, downlock, & Weight On Wheels (WOW))
• Thrust reverser actuation system (TRAS) (stowed or deployed
status)
DIFFERENTIATION
• Diagnostic capability: Integral Health Monitoring:
sinks 9 mA ±1 mA or <1 mA on fault detection
• Fire detection/integrity: Explosion proof RTCA/DO-160G
Section 9, Cat E&H
• Operational shock: RTCA/DO-160G Section 7, Cat B
• Crash safety: RTCA/DO-160G Section 7, Cat B
• Radio frequency emission: RTCA/DO-160G Section 21, Cat M
• Lightning induced transient susceptibility: RTCA/DO-160G
Section 22, Cat B3K3L3
