| Honeywell - banned for life over customer firewall |

A new design for a client had two candidates of PCB mounted pressure sensors. One was a Honeywell HSCMRNN001PG2A3. The other was an Amphenol Nova sensor. In PCB designs I always use 3D step files, never extruded approximations for fitment reasons, orientation and footprint verification. I could not find the Honeywell 3D step file anywhere online, so I emailed Honeywell in Australia, the US, and also filled in various forms on their website. The Honeywell website could not recognise their own part number when it is searched on. No response in two weeks from anyone, except one out-of-office email saying "On sick leave, response will be delayed." without any forwarding information. Maybe the employee was sick of Honeywell. This company is crap. You might as well be speaking to a brick wall. I have found over the last 30 years, Honeywell usually has important data missing from their datasheets, in this case no i2c resister information on the datasheet. In one case a few years ago their wrong data caused $1,200 worth of damage, as well as selling faulty parts that they refuse to take back. They also have poor part number, engineering control and documentation, and a bloated website with little useful information. The final straw was with this sensor. I spoke to my client and they have agreed to dismiss Honeywell as a supplier. Honeywell will lose significant sales as a result, now and in the future. Honeywell is now BANNED FOR LIFE. I don't think Honeywell employees care. Amphenol wins hands down. From the start all the data was available and detailed including the 3D step file. Even the i2c register data was all on their datasheet. Their sensor is a third of the price of the Honeywell sensor. But it does raise the question of how does one get to speak to a useful human in a "Your call is important to us" company, when the company builds a firewall between them and their customers? I heard Apple, Google and Facebook also fall into the customer firewall category. Bosch Sensortec is definitely in that domain. |

they are open loop gain companies now. closed loop feedback is too hard apparently If you think anyone cares in a congomolarate, you are wrong! maybe sales a little bit. But the status quo is to 'look for new jobs while you work here' for most big companies anyway. They really want nomad-style mercenaries to work there IMO. |

there's drawings in the datasheet, step files are nice but people got by with drawings for many many decades why do you expect i2c resistors to be in the datasheet? they are part of the i2c spec |

You cannot pull that stuff out of your head and no-one should not have to spend days trying to hack it. It is unique to the specific device. But of course it isn't in the effing datasheet. As for models, most of the products I design have tight enclosure or other physical constraints. I need to get it right the first time. Furthermore, I deal with industrial designers or mechanical engineers who need accurate information and rightly so. Your mobile phone was not created by someone using extruded models - they use proper CAD models. IMO, these days anyone using extruded models these days is either lazy, too busy, lazy, on too tight a deadline, lazy, sloppy, or just plain lazy. Having a PC or graphics card too slow to render a 3D board image, not enough RAM, or not disk storage these days is nonsense. 20 years ago, it was an issue, but not now. |
