Wilcoxon looks like it is part of Amphenol. Doesn't look like they have a relation to Meggitt.

Meggit bought Wilcoxon in 2013 and sold it Amphenol in 2017. I haven’t bought anything directly from Wilcoxon in 20 years, but their sensors are heavy duty and last forever, much longer than the PCB industrial sensors. Wilcoxon’s catalog looks substantially the same to me, based on what I’ve seen.

Wilcoxon.  Most reliable and shortest settling time I have ever had. And recently I have used IMI, Hansford Premium and CTC Premium accels. Wilcoxon wins hands down.

2140 is really quick on the draw and I don't know how many times I have had to recollect a point after ski slope with the non Wilcoxon accels. Model 786A if my memory serves me correctly. rgds  ps I don't sell them nor am I associated in any way.  My preference for a walk around route any day.

I use Wilcoxon as well and can't fault them, haven't used other brands for a long time.

Compression mode accels were the first generation as old as MCV's..like late 1940's.. and some vendors kept it long in to this millenium and some still use it, enhanced but still, some let you choose...... I know, I take them a part and look inside as I am like that.... I can post pictures adn use the corpses at training but I will not.

Oli, was it maybe a specific model? 
The datasheets of the most common models (786 general purpose, 780 compact version, 787 side exit, 786LF low frequency, HT786 high temperature) all say that they are shear mode.

So shear mode is considered better than compression? Why exactly?

I use to do sourveys on internal combustion engines with compression type, I had to swap accelerometer it gets hot and saturated very quickly, had to share my bottle of water with the accelerometer, use two accelerometers and constantly swap....


so basically compression mode are more sensitive to temperature and high settling time.

You bet in the classic style but there are design mods that improve on that.....
