000843 Issue 2 GAPS & HAPS SERIES Aerospace Proximity Sensors DESCRIPTION FEATURES Honeywell has over 30 years experience Industry-leading indirect lightning designing and delivering accurate and and dielectric ruggedness: Meets reliable proximity sensors that are the increased requirements of currently used in a variety of military and todays composite aircraft and most commercial aircraft. challenging applications including landing gear, thrust reversers, and flight Honeywell has two new platforms of controls proximity sensors: General Aerospace Proximity Sensors (GAPS) and Harsh Enhanced vibration ruggedness: Aerospace Proximity Sensors (HAPS), Capable of withstanding extremely high VALUE TO CUSTOMERS formerly known as the IHM Series. Both vibration applications Enhanced vibration and EMI platforms incorporate Honeywells specifications help to increase revenue Environmentally rugged: Fully hermetic patented Internal Health Monitoring (flight hours) and reduce cost to serve packages provide long-term reliability in functionality, however the products (system maintenance) very harsh environments by eliminating have some technical differences the potential for contamination of Hermetic sealing helps increase that allow them to be used in various the sensor from the application revenue (flight hours), reduce cost to aerospace applications. GAPS can be environment. In addition, Honeywell serve (maintenance), & reduce cost of used in less harsh areas of application has developed an innovative method to goods (spares) with some differences of electrical and environmentally seal wire-lead (pigtail) environmental characteristics when Platform approach helps to increase configurations compared to HAPS. Whilst, HAPS revenue and reduce cost to serve Internal Health Monitoring Capability: Aerospace Proximity Sensors are Health monitoring helps to increase Optional third output state to indicate configurable, non-contact, hermetically revenue, reduce cost to serve, and the health of the sensor (whether sealed devices designed to sense the reduce cost of goods it is healthy or failed). Reduces presence or absence of a target in harsh- maintenance time, reduces delayed Supplier stability helps to reduce cost duty aircraft applications. flights, and lowers overall maintenance to serve (troubleshoot with original The GAPS and HAPS platforms provide cost across the life of the aircraft supplier) on/off outputs and can be configured with Non-contact design: Utilizes non- Current install base helps to reduce an optional health monitoring output to contact technology to sense the cost to serve (proven performance and the host system. The sensing mechanism presence or absence of a target MTBF) is based on the familiar Eddy Current Killed regardless of the dirty, harsh Oscillator (ECKO) principles however, environment in which it is placed, Honeywell has designed and implemented eliminating mechanical failure the patented FAVCO (Fixed Amplitude mechanisms, reducing wear, minimizing Variable Current Oscillator) technology downtime, increasing durability, and which enables the Honeywell sensors to increasing reliability have the health monitoring (IHM) features. See Figure 5 to compare the ECKO and PORTFOLIO FAVCO technologies. The GAPS and HAPS Honeywells GAPS and Series helps to reduce downtime and HAPS Series is part of a maintenance costs due to a unique circuit comprehensive line of that can detect any internal failures and aerospace sensors, switches, display a fault output instead of a false and value-added solutions. positive or false negative.
