Texas Instruments LDC0851 Highly Accurate Inductive Switch
Texas Instruments LDC0851 Highly Accurate Inductive Switch is a close range inductive switch ideal for contactless and robust applications such as presence detection, event counting, and simple buttons. The switch is triggered when a conductive object comes within close proximity of the sensing coil. Hysteresis is included to ensure a reliable switching threshold immune to mechanical vibration. The differential implementation prevents false triggering over environmental factors such as temperature variation or humidity effects. Inductive sensing technology provides reliable and accurate sensing even in the presence of dirt, oil, or moisture making it ideal for use in harsh or dirty environments.Features
