Differential Inductive Switch delivers accuracy and reliability.

Press Release Summary:



Using coil drawn on PCB, LDC0851 detects presence or absence of conductive material. Magnet-less operation simplifies implementation, and design is immune to nonconductive contaminants, such as oil, dirt, and dust. Suited for proximity, position, and motion sensing applications, such as rotational encoders, buttons, and door open/close detection, switch does not require any calibration during production, delivers better than 1% switching accuracy, and operates at <20 µA at 10 samples/sec.



Original Press Release:



Industry's First Differential Inductive Switch Delivers High Accuracy and Reliability



The LDC0851 detects the presence or absence of a conductive material by using a simple coil drawn on a printed circuit board (PCB). It provides designers a reliable, low-cost option for proximity, position and motion sensing applications such as rotational encoders, buttons and door open/close detection. In addition, the device does not require any calibration during production, saving time and cost during manufacturing.



Key features and benefits:

• Simplified design: magnet-less operation eliminates the complexity, size and cost issues in traditional implementations.

• High accuracy: delivers better than 1% switching accuracy, which is up to 10 times more accurate than designs than magnet-based sensor designs.

• Low power: operating at less than 20 µA at 10 samples per second, consumes less power - as much as five times less - than competitive optical sensors.

• High reliability: immunity to nonconductive contaminants, such as oil, dirt and dust, helps extend product life.
