Enhanced vibration and EMI specification; hermetic sealing; design to meet requirements of today’s composite aircraft

September 2017: Aerco, the distributor and stockist of electrical and electronic components servicing hi-rel markets, is now stocking Honeywell’s IHM Series Aerospace Proximity Sensors, which boast industry-leading indirect lightning and dielectric ruggedness, plus enhanced vibration and EMI specifications to meet challenging applications found in today’s composite aircraft.  Highly accurate and reliable, Honeywell IHM Series Aerospace Proximity Sensors are non-contact devices designed to sense the presence or absence of a target, providing on/off output, plus they can also be configured with an optional health monitoring output to the host system.

Honeywell IHM Series Proximity Sensors have a hermetically-sealed, all-welded stainless steel construction for 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 IHM Series 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. 

Honeywell has over 30 years’ experience designing proximity sensors for military and commercial aircraft, and designed the IHM Series with its patented FAVCO (Fixed Amplitude Variable Current Oscillator) technology circuit. The sensor is considered an improvement on traditional ECKO (Eddy Current Killed Oscillator) topology, which was the previous standard for aerospace applications. Honeywell IHM Series Aerospace Proximity Sensors detect and display a greater percentage of internal failure modes than competitive products. Examples of suitable aircraft applications include: status of doors (open/closed/locked); cargo loading latch detection (pallet locked); evacuation slide door-lock mechanism (correct actuation); flight controls (flap and slat skew/position and spoiler position); landing gear (uplock, downlock and Weight on Wheels) and Thrust Reverser Actuation System (TRAS) (stowed or deployed status).

The Honeywell V Series of waterproof, sub-miniature switches that is now available from Aerco provides a cost-effective sensing of presence or absence of an object.

Watertight to IP67, the V Series provides a wide selection of actuators, terminations and wire connections, offers a wide range of current ratings from 0.1 to 10.1A and is approved to UL/CSA, cUL, ENEC and CE.  It is the only V-switch in the industry rated up to 10 amps.

These characteristics, together with their small size and weight and high levels of reliability, make the switches highly suitable for high-current applications where spillage or water could be a factor such as are found in off-road vehicles, lawn mowers, snowmobiles, construction and agricultural machinery, industrial, office, medical and communication equipment, computers, electrical tools, heating and ventilation controls and marine systems.

Specific models can be supplied with wires pre-­attached to reduce installation times.

The Honeywell NBP series of board-mount pressure sensors is now available from Aerco.  Designed to provide a high resolution, high quality cost-effective sensor for medical and industrial applications, these sensors are ideal for users who want to provide their own compensation, calibration and amplification. 

The NBP series measures absolute or gauge pressures.  The absolute versions have an internal vacuum reference and an output value proportional to absolute pressure.  The gauge versions are referenced to atmospheric pressure and provide an output proportional to pressure variations from atmosphere.   These sensors are intended for use with non-corrosive, non-ionic gases, such as air and other dry gases and for non-corrosive, non-ionic liquids.  All products are designed and manufactured according to ISO 9001.

Measuring only 7mm x 7mm, sensors in the NBP series are smaller than most board-mount pressure sensors and therefore are easier to place on densely-populated PCBs or in small devices.  Highly durable, they are ideal for tough environments and have an operating temperature range from -40 °C to 125 °C

They are available with either gel or non-gel coating and in numerous package styles, pressure ranges, housings and porting options and therefore provide a high degree of design flexibility allowing simple integration into many medical and industrial applications.
