Military-grade angle sensors introduced

Engineers at Jodan Technology Inc. of Lexington, Mass., are announcing non-contacting magnetic sensors for severe environments that measure rotation angle in feedback and control systems. These devices, called hallpot potentiometers and Sin-Cos hallpot resolvers, operate in temperatures between -40 and 125 degrees Celsius, and are designed to withstand military ranges of shock and vibration. These devices produce large output signal voltages, which can be rail-to-rail over the operating angle. They produce signals using the Hall Effect, which has no physical contact and so has no inherent wear. For more information, contact Jodan by phone at 617-863-8898, or by fax at 617-863-0462. - J.K.
