Viable for military and defense apps, the HSTAR 750 Series hermetically-sealed position sensors serve as single- or multi-channel devices depending on redundancy and reliability requirements. Most perform in quad-channel systems for military aircraft as well as land vehicles, serving as feedback devices on active suspensions for load and artillery-platform leveling. Options for HSTAR 750 units include metric threaded cores, smaller diameters, and low-mass cores. On special order, the sensors are available for immersion in pressurized fluids and exposure to radiation at 3x107 Rads for 40 years. The 19-mm diameter, ac-operated sensors are available in ranges of ±1.25 mm to ±250 mm. MACRO SENSORS, Pennsauken, NJ. (856) 662-8000.
