content: I hope this is a good subsection for this question.Have any of you guys interfaced "MNO2 & MNO2B MediceLs" sensors?https://prod-edam.honeywell.com/content/dam/honeywell-edam/sps/siot/en-us/products/sensors/gas-sensors/7-series/documents/sps-siot-citytech-mno2-sensor-datasheet.pdfThe datasheet mentions additional information:"This document should be used in conjunction with the Product Data Handbook (mtoxops.pdf) and the Product Safety Datasheet (PSDS 5 for MNO2, PSDS 5B for MNO2B)."While I wait for the Honeywell support to react, I thought I give it a shot and ask if anybody has those documents at hand. My google-foo is too weak and I can't find these documents online.Thanks in advance!Edit: I first posted this in the Metrology section. Since this section may be better suited, I asked the mods to reposition it. Thanks, Simon!

content: I am still looking for any kind of information around the MNO2 & MNO2B MediceLs. Component order code is AF7F4-400. I am especially looking for a document "mtoxops.pdf" and characterization documentation analog to aq7so2 and/or recommended application interface (schematics).To access this kind of "privileged information", Honeywell asks you to register with their "sps-support.honeywell.com". That portal seems to have technical issues.When I contacted the address that is supposed to solve those issues, a (I guess) human asked me to try again. I then provided a screenshot of the crashed site.That started some gears to grind into action, some repairs happened and I was asked to try yet another sign-in.Well, that worked. Now I could interact with a "chatbot". That abomination didn't recognize any keywords, neither product order code, nor document names.At that point I told Honeywell that I will forward my "findings" to my client, who then may decide how to procede.No way to contact a human that is willing to actually help out and all the "support" is a buggy chatbot. I remember better days regarding customer support.

content: I finally got the go to rework a pre-amp board for this cell. We never got any feedback from the manufacturer. My client is still looking into this topic.From the datasheet:"Important Note: Connection should be made via recommended mating parts only."At the moment I am looking for a search term for recepticle contacts for the cell's pins. Pins are shown in the datasheet as 1mm diameter, 3.4mm long.The old PCB has vias, where those recepticles are soldered into place. Before somebody asks - my client has no BOM's anymore.Edit2402221526: We use Mill-Max 7406-0-15-15-18-27-10-0, available from distris, e.g. Mouser.

content: Update: my client has changed their sales contact. A very excited head of development sent me this text today, with the "Doc. Ref.: mtoxops.pmd Issue 5.0" attached:->Check out those timestamps:Query: Thursday, February 22, 2024 12:31 PMAnswer: Thursday, February 22, 2024 13:42 PM<-While I am not a liberty to share the contact's details, I can at least let you guys know that there are more intrepid sales reps around - who actually help the client.The document itself is rather helpful and promptly showed me an unnecessary limition in a previous prototype implementation. Good stuff!Best of all - I confirmed that no NDA applies to that document! Enjoy.
