Novotechnik has introduced the Contelec Vert-X 21 LP series of low power sensors. These noncontact angle sensors consume 300 µA of current at a power supply level of 3.3 V. Other specifications include 0 to 360° measurement range, 12-bit resolution, repeatability to 0.1°, and maximum hysteresis of 0.2°. Power supply is 1.8 to 5.5 V. Vert-X 21 LP series sensors are offered as a three-wire angle sensor or as a programmable version with up to two switch outputs, custom measurement angle, start and end-point settings, custom characteristic curve, and/or sense of rotation. Compact designs are less than 1 in (25.4 mm) in diameter, sealed to IP65, and offer life of more than 360 million movements. Applications include robotics, battery-powered devices, joy sticks, and control valves.
