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. The LDC0851 does not require an MCU to operate, allowing for a simplistic solution.
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. The solid state switching eliminates the failures due to reed, mechanical, or contact switching. Unlike competitive products, the LDC0851 does not require magnets, nor is it affected by DC magnetic fields.

The LDC0851 evaluation module demonstrates inductive sensing technology to accurately detect the presence of a conductive target passing a fixed threshold. The evaluation module includes a perforated and interchangeable 4-layer PCB where both the sensing coil and reference coil are stacted for (...)
The inductive sensing calculator tools provide two Excel spreadsheets to assist in the design process for inductive-to-digital converter (LDC) devices. These tools provide coil design assistance as well as some device-specific configurations.
