Honeywell IHM Aerospace Proximity Sensors
Honeywell IHM Series Aerospace Proximity Sensors are customizable, non-contact, hermetically sealed devices designed with advanced technology over the classic ECKO (Eddy Current Killed Oscillator) topology that was once the standard in aerospace applications. The IHM sensors include a unique circuit that can identify any internal defects and display a fault output instead of a false positive or false negative, reducing downtime and maintenance. These IHM aerospace proximity sensors feature an operating temperature range from -55°C to +115°C and are available in supply voltage ranging from 12Vdc to 28Vdc. Ideally, IHM sensors are used in TRAS (Thrust Reverser Actuation System), flight controls, landing gear, and evacuation slide door-lock mechanism.
