Hi checking if there is interest here for a product like this, as I deal with a bunch of customers in the industrial market segment.Popular type switches in this segment are Hirschmann RS20 and on the lower end we see here and there Mikrotik Netpower 16P. Increasingly we are seeing the Chinese heavily enter this segment and there is quite a bit of pushback in this vertical against their equipment.
Most are L2 only and usually feature a some form of console power in the enclosure for troubleshooting.
Switches can usually take multiple dc blocks and have poe power out on most of the ports to power up wifi/iot/surveillance. Units usually sit in no enclosure and have some form of rating against dust/water.Connectivity back to the IDF/MDF usually via sfp+ ports.
