Melexis release IMC technology in its Latch & Switch product range

Using the lateral field rather than the perpendicular field.

Melexis, a global microelectronics engineering company, announced the rollout of its Integrated Magnetic Concentrator (IMC) technology to multiple devices within its Latch & Switch product range.

Melexis’ Latch & Switch sensors use the magnetic Triaxis technology that allows the measurement of the lateral magnetic flux component.

As a result of the inclusion of IMC technology, wheel speed sensing on motorcycles can now be performed using a single two-wire switch sensor with integrated capacitor (MLX92242 or MLX92241) and a traditional magnet. This approach uses the lateral field rather than the previous method of using the perpendicular field.

As brushless DC (BLDC) motors become an increasingly popular choice for many applications including blowers, cooling fans and pumps, more sophisticated control is required. Melexis say that by integrating an IMC into products, such as the MLX92211, surface mount sensing is available, thereby simplifying the production process and reducing the space required.

With devices such as the MLX92231, the MLX92291, the MLX92211, the MLX92232 and the MLX92292, which are commonly used in automotive applications such as transmission selectors (gear shifts) and HMI interfaces, the inclusion of an IMC allows the magnet to be placed beside the sensor. As a result space can be saved and new applications enabled, where previously there was not enough room for a magnetic sensing solution.
