AFX Termination

Small diameter heaters have small diameter terminal pins into which the lead
wire is crimped.  Generally, this is not a problem because the wattage is not
too high and the amperage is very low.   But if the application requires higher  
amperage-carrying ability or resistance to repeated flexing, larger diameter  
wire must be employed.

When small diameter pins exclude the use of larger gauge wire, the AFX
termination is an effective way to go.  A tapered pin is used to accommodate
the larger O.D. of the wire and the smaller end is welded onto the terminal pin.

One other benefit of this construction is that the wire is inserted into the termination
with the primary insulation.  When a wire is crimped into a terminal pin, that crimp
becomes the focus point for any flexing and stress on the wire.  But the AFX termination
includes the insulation and provides additional support for the wire with the insulation. 
It also displaces the focus of the stress to a point that includes insulation.

This is an ideal construction if you have a small diameter heater and the need for
higher amperage capacity or protection against finer wire breakage due to flexing
or cycling as in a packaging machine.
