"The Honeywell SR4 series hall-effect position sensors come in a sealed threaded housing. They respond to the magnetic field of permanently positioned magnets or electromagnets, responding to either an alternating north or South Pole or to South Pole only. A wide variety of digital unipolar, latching, and linear magnetic types are available in a number of sensitivities depending on the application requirements. They can easily be easily interfaced with common electronic circuitry such as microprocessors, integrated logic, discrete transistors, and SCRs with compatible voltage specifications.Body Style = BarrelMounting Style = Cable MountSupply Voltage = 4.5 - 30 V dcTerminal Type = ScrewMaximum DC Voltage = 0.4VSwitching Current = 20 mALength = 25.4mmWidth = 12.45mmDimensions = 25.4 x 12.45 mmMaximum Operating Temperature = +85°C"
