Hello
Could you explain what the (AT) unit of measure means? It is used to describe the Operating Range.
Thank You
Patrick
Greetings,
It stands for Ampere Turns and is a measure of switch sensitivity to magnetic field, describing the field strength required to actuate the switch in terms of the product of the number of windings on a test coil (electromagnet) and the current flow through that coil.
Datasheet footnotes are often a good place to discover resources on such topics, because the numbers in a datasheet don’t mean very much at all unless the conditions of measurement are also stated. See excerpt below for example.
