| 1 mm accuracy IC sensor |

| Klemken:
Hello, anyone knows of any distance IC sensor (max size similar to a TQFP48 package), touchless (laser, tof ,reflective,... ), with accuracy of +/- 1 mm. Distance i need to sense is 1 mm to 100 mm. I checked ton of site but best i found in this size had accuracy of +/- 5mm. Thanks for any help in advance. Kind regards. |

Given your size requirement, I kind of doubt you'll find anything like that. Example of sensors that could match your accuracy/range requirements: https://www.sensopart.com/en/products/distance-sensors/distance-sensors/ft-25-ra-170-pnsul-m4m.html Definitely not small and likely rather expensive. Many of the usual sensors are closer to +/-5mm, and I'm personally not aware of any that would entirely fit within a TQFP48 envelope. If you can disclose your application, we may be able to find some alternative ideas... |

Would attaching a pattern on the other surface and using a camera be an option? |
