How much distance it can detect and when test this sensor with 120mt when I place the magnet it detects only up to 1cm why?
@Melexis_Sensors9 күн бұрын
The distance IC/magnet heavily depends on the choice of the magnet. But for a general answer you can expect a distance between 5 and 25 mm (and more if you would design a magnet for it). Here is an application note that could help www.melexis.com/en/documents/documentation/application-notes/application-note-how-to-use-a-magnetometer-in-a-position-sensor-application

Hello, how would this sensor differ from the 90363? I'm doing a DIY project and found this sensor for sale at a local store, but the guide I'm following talks about the 90363, which is unavailable here. Thanks.
@Melexis_Sensors2 ай бұрын
Hi, it won't be possible to simply replace the MLX90363 with the MLX90393. The MLX90393 is a completely different IC. The MLX90393 can only provide X/Y/Z data and uses a reduced and simpler command set, whereas the MLX90363 can also directly provide the angle for rotary, linear position, or joystick applications.

Why aren't encoders made with magnetic tape and tape reading heads, like in audio cassettes?
@BrunoBrajon8 ай бұрын
Fun fact: when the audio cassette industry faded, some companies producing the magnetic tape needed to reinvent themselves. Therefore, they used a very similar technology to become the main providers of magnetic scales for encoders. The working principle is quite close actually even though the encoding of the position is different and in this case the 'reading head' is a more advanced triaxis hall sensor.

- Absolute or incremental? I'm guessing absolute, looking at the "Vernier" arrangement of the poles at 2:14. - How about (in)sensitivity to radial displacement? - Where does one procure the patterned (ring) magnets? -Readout speed? What peak-angular-speed is legible?
@BrunoBrajon8 ай бұрын
- Good guess. The encoder is absolute. - Due to the bigger size of the Master track which is providing the accurate angle, the effect of the crosstalk coming from the Nonius track is reduced with consequent improved robustness against radial wear-out (which normally causes crosstalk variation). - Magnet can be customized according to specific design rules. Distribution strategy is still being defined. - Noise performances are specified for 1ms refreshing rate. For intermediate product, readout period is 80us. For the final product it will be possible to readout angle and speed at periods as small as 15-20 us.
@AdityaMehendale8 ай бұрын
@@BrunoBrajon Thanks!! Is there a limit on the angular speed of the rotor? A dentist's drill (for example) runs at ~100k RPM i.e. ~1e4 rad/s. I can imagine that the sensors might have trouble reading the angle (albeit with aliasing) as the rotor-magnet would travel almost 50 deg in an 80us window.
@BrunoBrajon8 ай бұрын
@@AdityaMehendale The sensor includes look-ahead angle correction for very high-speed applications. The maximum speed of rotation the sensor can work at depends on the number of pole pairs on the Master track. In general Max rotation speed is equal to 200krpm/Number of polepairs on the Master track. With the magnet shown in the video, this is equal to 25 krpm

PCB less solution makes big advantage in cost first of all. Other big benefits are vibration proof, easiness of assembly process, much more compact size. This IC is hybrid like mentioned in the video - for example it contains additional decoupling capacitors, so no need to add them externally. In case PCB is present, you need to protect it by polymer compounds from moisture and to improve mechanical properties to match automotive requirements, here this is not needed. PCB less solution is very attractive for sensors like magnetic or pressure, especially in automotive hursh environment.

50% of what? The ratio of the dT between the (sensor and the background) and the (sensor and target) shall influence the nature of the distribution as depicted at 2:09. ..or do you somehow ensure that the b/g is at the same temperature as that of the sensor (dT_1 = 0) before carrying out this experiment?
@vsp_tof Жыл бұрын
50 percent of normalized graph. We are not interested in absolute values returned from the sensor in this experiment that is why normalisation is done. Ideally the temperature of the object should be high enough to have clear graph. Normalized graph is not much sensitive from the temperature value itself. Definitely, object should be hot enough to be easily distinguished from the background and same time not to saturate the sensor. And yes, as any FIR sensor, it has its internal temperature sensor for compensation. You are right, ideally sensor temperature should be as background, but for most cases with proper object temperature selection, this requirement is not so strict.

I know this video is a bit dated and for a singular product, but does Melexis offer anything for simultaneous 6dof (xyz linear and xyz rotation) movement? If not, in what way could a set of chips (not necessarily the 90395, any product) be utilized to handle simultaneous 6dof movement? I remember years ago, if not over a decade at this point, Fraunhofer IIS had their HallinOne sensor that, in theory at least, could handle 6dof, though I've never been able to find a standalone IC for their product. Fraunhofer also has a IC diagram showing how individual sensors are placed within the chip, IIRC 12 sensors in various orientations, are Melexis products designed in a similar way, in theory at least, compared to the HiO sensor? I'm only asking for a better understanding of the IC package itself, I found the HiO design interesting, though Fraunhofer never really explained the data side of their implementation, so I'm curious if Melexis has a similar or different approach to 3D magnetic sensing.
@Melexis_Sensors Жыл бұрын
The MLX90395 measure the magnetic field in three directions (X, Y, and Z), using horizontal Hall elements combined with and integrated magnetic concentrator, and outputs these measurements as a digital value relative to the magnetic field strength. . The actual position (angular or linear displacement) can be calculated using the data that is provided by the sensor. More information on our IMC (integrated Magnetic Concentrator) can be found here: www.melexis.com/en/tech-talks/triaxis-position-sensing-solution
@xaytana Жыл бұрын
@@Melexis_Sensors This doesn't really answer my question of if the chip is capable of simultaneous 6dof or not, and none of your materials explain if this is possible either. It's really as simple as a yes or no answer, yes it can do simultaneous 6dof, or no the chip is limited to a certain degree of freedom. I just want to know if I can have both a spatial position of a magnet and 3D rotation (better described as a quaternion) of said magnet, simultaneously. Or does your product lack the amount of sensors that would make this possible. I.e. is this similar to the Fraunhofer IIS product, which does true spatial measurements with a higher number of sensors (IIRC 12 sensors), or is it more similar to the products that Texas Instruments and Infineon produce where it's only one sensor per axis and thus has a more limited degree of freedom?
@Melexis_Sensors Жыл бұрын
@@xaytana Thanks for reverting back, please allow us to give a bit more background to the previous answer. As already indicated in your previous reply you were using a reference of the HallinOne approach from Fraunhofer. This HiO cell is nothing more than a combination of 2 vertical hall sensors and 1 horizontal hall to measure the 3 different magnetic field components. In our Melexis solution we are not using vertical hall technology but we are using our IMC technology in combination with planar hall technology our concentrator allows us to convert horizontal field lines into a vertical component which we then use to measure the 3 different field components. So both principles (HallinOne or our Triaxis technology) will give you the raw data signals for the 3 different field components. The Integrated Magnetic Concentrator is offering a certain gain and is resulting in better performance (offset and sensitivity) compared with vertical hall technology. So to answer your question our chip will provide the data for Bx,By and Bz allowing you to use the 3 vectors (simultaneously) for further post processing.
