DESCRIPTION
The LDC0851 is a close range inductive switch ideal for contactless, simple switch applications such as presence detection and event counting. 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. The differential implementation prevents false triggering over environmental factors such as temperature variation or humidity effects.
