MLX92442
2 and 3-wire Induxis® latch & switch
Central to the MLX92442 is its heavily integrated and miniaturized standard packaging. Compared to other inductive solutions, Melexis's design innovates by fully integrating the coils and interface within the chip, removing the need for engineers to develop bulky PCB and coil solutions for their application.
Besides reducing the BOM component count, Melexis induxis® solution helps to streamline development time. Both factory and end-of-line programming are supported, and the smart switch/latch operation is established by simply defining the applications’ shape and motion.

New technology. Engineering samples available in limited quantities
Regarding assembly design, the standard packaging allows for simple system integration. This factor helps to maintain mechanical tolerances in assemblies, as only the inductive sensor and conductive safety element need to be considered within air gaps up to 1.5 mm.
With industry-standard two or three-wire interfaces, a wide operating voltage of 3.5 V to 18 V, a working temperature window of -40°C to 150°C, and ISO26262 ASIL A compliance, the MLX92442’s design considerations are minimal. Furthermore, for safety-critical applications requiring heterogeneous redundancy, the inductive technology provides a highly reliable option with minimal design requirements that can operate next to the Hall effect and mechanical solutions.
The solution is available in through-hole VK packaging or surface-mount SOIC packaging.
