Proximity sensors handle extreme environments

The sensors feature enhanced vibration and EMI specifications, which help to increase flight hours and reduce system maintenance.

A hermetically-sealed, all-welded stainless steel construction provides exceptional robustness and durability in harsh environments, eliminating any potential for contamination.

Due to their non-contact design technology, Honeywell IHM Series Proximity Sensors detect the presence or absence of a target regardless of the often very dirty conditions in which they operate, thereby eliminating mechanical failure mechanisms, increasing revenue and reducing maintenance costs by increasing Mean Time Between Failures (MTBFs) and so minimising downtime.

A further feature of the sensors is the optional third output state to indicate the health of the sensor (whether operating optimally or failed), which again reduces maintenance time and delayed flights, helping to lower overall maintenance costs across the lifetime of the aircraft.

As the IHM Series offers a platform approach, engineering investment in product is lowered, and speed to market is increased.

Suitable applications include cargo loading latch detection; door status (open/closed position; locked status); evacuation slide door-lock mechanism; flight controls (flat/slat, spoilers); landing gear (uplock, downlock and Weight on Wheels); and thrust reverser actuation system (TRAS) (stowed or deployed status).
