DATA SHEET The 0717-4304-99 TrueTilt Sensor” represents a new advancement in electrolytic tilt sensor technology. Robust all metal construction provides durability as well as superior dimensional tolerances, which equates to excellent sensor-tosensor electrical performance. This sensor is ideal for economical, commercial market applications requiring high production quantities and first-rate accuracy. Angle Range Resolution Repeatability Applications Include Wheel Alignment Navigation and GPS Compensation Automotive Roll Over Game Controllers and Joysticks Medical and Physical Feedback Instruments Physical Dimensions Height Diameter – Cap Diameter Flange Lead Length Lead Diameter Lead Spacing (center to center) Sensor Test Circuitry Tests were conducted by exciting the outer electrodes of a single axis with an AC signal of 400 Hz and an rms voltage to produce the maximum current at null as per operating specifications. Output readings are taken between the center electrode and the center of the balanced resistors R1 and R2. Tests were conducted at a temperature of +25 C. See test circuitry in figure 3. Output curve is shown in figure 1. 60 Operating Range (max.)
