IWR6843: is it possible to use mmwave in place of light curtain (for hand protection)?

Part Number: IWR6843

Light curtain for hand protection devices are sil2 devices. and the resolution of that devices are 30mm. I wonder if we can use mmwave in place of light curtain(hand protection)? can we create 2d scan zone?

Also is there a SIL-2 version of iwr6843boost card?

  • Hi Erdem,

    I'll need to discuss this with my team, we should have an answer for you next week.

    Hi Erdem,

    Our IWR6843 devices are targeted for SIL-2.

    Need some more clarification on 30 mm resolution requirement: Is it min. distance from sensor, or min. distance b'n two objects to distinguish them apart or are you referring to accuracy.

    Thanks

    Hello Yogesh,

    Thank you for your answer. 

    Please check the explanation

    Resolution (R) is also called Minimum Object Sensitivity (MOS) or Detection Capability. This is the smallest diameter (object) that a safety light curtain system is capable of detecting with absolute certainty. This figure describes the resolution of the safety light curtain system:

    R = P + E where:

    P = distance between the axis of two adjacent beams. E = diameter of the beams.

    By the way i need to correct my question. The light curtain's safety category is SIL1(categori 2 PL c) not SIL2 for my application. And the minimum resolution is 20mm not 30mm.

    Hi Erdem,

    We are still looking into it. Will come back in a day.

    Thanks

    Hi Erdem,

    You may need to carry out experiment similar to:

    http://dev.ti.com/tirex/explore/node?node=AJWaDzkjXCZGhvD9P6WzBg__VLyFKFf__LATEST

    This will be clearly tell if your requirement will be met or not with the restrictions you may have. 

    Thanks

    Hi Erdem,

    Let me know if you need any support in running the experiments or have any concerns.

    Thanks

    Hello Yogesh,

    Thank you for your support. I have checked the link you gave me. I guess iwr1443 and iwr6843 are working as an area scanner. Defining a 2d scannig area is not possible.like the image seen below.  

    Could you tell me the response time for the out of box application. and can i use the same code(out of box code) with sil-2 iwr1443/iwr6843?

    Regards 

    Erdem

    Hi Erdem,

    Will comeback on response time for OOB demo. 

    For any safety related questions , please contact your local TI sales who can provide more details 

    Thanks

    Hi Erdem,

    Currently we do not have data on response time. It is dependent on the chirp config. Could you please provide the response time requirement that you are looking for.

    Thanks

    Yogesh
