Littelfuse reed sensors in the 59145 series have an A or F suffix option. Looking at these parts they appear to be the same, what is the difference?
The difference is the end of the wire leads, A has Tinned leads (6.4±0.76)mm and F has Untinned leads (6.4±0.76)mm.
Magnets are sold separate for these sensors so don’t forget to order one of these also, Digikey parts 57145-000-ND and 57150-000-ND are two options to look at.
