My boss gave me two of the item shown in the photograph.
I think its a DIN Rail end. Its connection to the DIN Rail is not spring loaded.
There are no wire contentions. Mi or Hi is on the device, like a logo.
My search of the internet was unsuccessful - I did not find the manufacturer or a part number.
Anyone know the manufacturer and part number?
DIN rail devices are quite standard and replaceable, and the one above seems to have the function of restraint against displacement in case of vibration. I had already used screwed end-clamps from Phoenix Contact.
