## Aerospace Proximity Sensors IHM Series 

## Datasheet 

## FEATURES 

- 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 wirelead (pigtail) configurations 

## 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, hermetically sealed 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) 

- 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 

- Thrust reverser actuation system (TRAS) (stowed or deployed status) 

- Doors (open/closed position, locked status) 

- Cargo loading latch detection (palet locked) 

- Evacuation slide door-lock mechanism 

- Flight controls (flap/slat, spoilers) 

- Landing gear (uplock, downlock, & Weight On Wheels (WOW)) 

## DIFFERENTIATION 

- Diagnostic capability:  Integral Health Monitoring: sinks 9 mA ±1 mA or <1 mA on fault detection 

- Honeywell has developed an innovative method to hermetically seal wire-lead (pigtail) configurations 

- 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
