S
HIPMENTS
4
All incoming shipments should be checked for damage during
transportation. The inspection should occur while the freight carrier is
present at your location. Any damage should be properly noted on the
delivery receipt.
4
When using a fork lift or hand cart, be careful not to bump the outside
of the packaging as this may damage the magnet wire.

TORAGE
4
Avoid double stacking the wire pallets.
4
Store packages on their original pallets and keep unused spools safely
stored in their original packages until needed. Store the wire package
in a dry, non-corrosive location. Keep the wire protected from dust
and other contaminants.
4
Spools should be placed back into their original packaging and
maintained in a manner to prevent damage with other items,
including other spools.

Fine Wire Handling Suggestions

ANDLING
4
Do not stack spools outside of the original Essex packaging.
4
When removing spool from its original packaging, be sure that it can
be freely removed without the risk of touching anything, including the
packaging itself.
4
To protect the wire enamel, do not remove the spool wrapper until
ready to load the spool onto the winding equipment. Use extreme
caution when removing the tape from the wrapper and place
wrappers back in cartons for reuse.
4
Care should be taken when handling spools near jewelry, metal
objects, or chemicals; contact may damage the wire enamel.
4
Avoid placing your fingers too far into the packaging handling slots;
contact may damage the wire enamel.
4
Carry the spools by using the provided hand holes or handles.

4
Check top flanges for any damage; use very fine grit sand paper to
remove minor nicks on the flanges.
4
If the spool is to be returned to its original packaging for later
usage, please secure the loose end by tying it to the flange.
4
Keep the spool as straight as possible when inserting into a
payoff shroud.
4
Maintain proper tension control during wire payoff.

Fine Wire and Ultra Fine Wire Manufacturing Locations.
Note: This table is provided as a general guide only; the appropriate winding
tensions may vary depending on a number of factors including product application.
The type of winder, payoff device, and type of coil may vary the tensions to be used.
In general, use the minimum tension that provides a good winding. Some minor
variations in the softness of the wire from one lot to another may also dictate minor
adjustments in winding tension.
1. Using the yield strength of fully annealed wire as a point of reference, tensions
beyond these may cause excessive stretching and high coil resistance.
2. Maximum recommended tensions are based upon 10,000 p.s.i. for copper.
3. Theoretical dimensions for sizes 45 AWG and finer.
Note: Start-up acceleration surge can produce tensions well in excess of
production tensions and need to be taken into consideration.
