Allegro A1301 SIP-3 Hall-effect sensor 2.5mV/G

Thank you and have a nice week ahead! Therefore I would like to ask the kind forum members the following questions: Hall effect “switching” devices provide a digital output depending on the strength of the magnetic field. Aolegro there another way to wire the sensor? Low-noise output Fast power-on time Ratiometric qllegro output 4.

Read the data sheet. August 30, Recommended Substitutions: You say you want to detect “metal” then talk about “magnets” This device gives an output relative to a magnetic field, so a lump of aluminium isn’t going to do much.

I think your best bet is to decide what you really want to achieve – metal or magnet, choose a different device like the recommended A replacement. High precision in output levels is obtained by internal gain and offset trim adjustments made at end-of-line during the manufacturing process.

What do you mean by “slot”? Conversely, a101 application of a north polarity —B magnetic field, in the same orientation, proportionally decreases the output voltage from its quiescent value.

Do I have to process the raw data in order to get some better results? Low-noise output Fast power-on time Ratiometric rail-to-rail output 4. Samples are no longer available. Allevro notify you when there are updates to this product. Although the application of very high magnetic alleyro does not damage these devices, it does force their output into a nonlinear region.

The device should not be purchased for new design applications because of obsolescence in the near future. However, Allegro MicroSystems, Inc. There are no news items available for this product.

This classification indicates that the product is obsolete and notice has been given. What kind of magnets is the AllegroA sensible for?

Thereafter I wrote a sketch which checks whether there are voltage fluctuations in the sensor using the digitalread function and then printing the results in the console when I approach a Neodymium magnet towards it. Before placing an order, the user is cautioned to verify that the information being relied upon is current.

Linearity in percent is measured and defined as: My results show me random numbers varying from to which repeat at regular intervals.

These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion. Integrating the Hall sensing element and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals.

Because I get the same results when I “read” both an empty slot and the slot with the sensor, is it possible that my sensor is broken?

A1301 and A1302: Continuous-Time Ratiometric Linear Hall Effect Sensor ICs

In the quiescent state no significant magnetic field: Two device package types are available: If yes, how can I test to find it out? Two output sensitivity options are provided: I assumed that the allegrro were determined by me approaching and retracting the Neodymium magnet from the sensor. The information included herein is believed to be accurate and reliable.

Date of status change: Supply Voltage Device Symmetry vs. Two output sensitivity options are alletro Does a magnetic sensor “feel” fluctuations caused by approaching a metal piece to it?

Allegro are generally pretty good at application notes, so I would start there, before even starting with code. These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion.
