https://docs.emtronaustralia.com.au/sensors/datasheets/rotary-switch-10-position/index.htmlDescription The Emtron Rotary Switch is a high quality 10 position Rotary Switch that produces a stepped output voltage for each change in switch position. The output voltage will swing between ground and the supply. The switch is terminated with the reliable and environmentally sealed Deutsch DTM connector. Features High quality single deck Grayhill rotary switch. Suitable for medium to high shock environments. Rotor contact: Brass, silver over nickel plate. Common ring: Brass, gold over silver over nickel plate. Max Supply Voltage: 5.00V to 20.00 Volts DC. NoteNOTE The supply MUST be regulated to generate a stable and consistent output voltage. Current supply: 4.5mA at 5.0V; 7.3mA at 8.0V The output voltage has linear stepping as the switch position changes. 5V Supply: Approximately 0.450V per position change (see calibration data below) 8V Supply: Approximately 0.720V per position change (see calibration data below) Calibration Data Output Voltage (V), 5.0V Supply Rotary Position Output Voltage (V), 8.0V Supply Rotary Position < 0.225 Fault < 0.365 Fault 0.451 1 0.727 1 0.901 2 1.448 2 1.350 3 2.175 3 1.815 4 2.924 4 2.238 5 3.610 5 2.702 6 4.350 6 3.142 7 5.055 7 3.597 8 5.763 8 4.039 9 6.428 9 4.481 10 7.100 10 > 4.770 Fault > 7.65 Fault Wiring Deutsch 3-Way Connector PinoutHugoen-us
