Figure 1
1. INTRODUCTION
EP-II contacts (reference part number 1744200-1) can
be extracted from the receptacle housing (2132781-5,
ref) using a commercially-available precision tweezer
with a
tip width of 0.38 mm [.015 in.] and tip thickness
of 0.25 mm [.010 in.] (approximately). Common
listings of this type of tweezer are Pattern 6, MM, or
SA, Type 6, 6-SA, or MM, and MM Boley style.
Read these instructions thoroughly before removing
any contacts from the receptacle housing.
NOTE
Dimensions are in millimeters [and inches]. Illustrations
are for reference only and are not drawn to scale.
Reasons for reissue of this instruction sheet are
provided in Section 5, REVISION SUMMARY.
2. DESCRIPTION
When properly grasping the locking ramp of the
receptacle housing, the tweezer is used to raise the
locking ramp from the contact locking window, allowing
the contact to be removed from the back (wire end) of
the housing. Refer to Figure 1.
3. EXTRACTION PROCEDURE
If the break-away contact retainer is installed in the
receptacle housing, remove the retainer before
attempting to remove any contacts.
CAUTION
Attempting to remove a contact with the break-away
contact retainer installed in the receptacle housing will
cause damage to the retainer.
1. Place the receptacle housing on a flat surface
with the locking ramps facing up.
2. Grasp the wire of the contact to be removed, and
push the contact toward the front (mating end) of
the receptacle housing so that the front of the
contact locking
window is away from the locking
ramp. See Figure 2,
Detail A.
3. While keeping the contact in place, position the
tweezer under the locking ramp so that the tips
straddle the contact locking window. See Figure 2,
Detail B.
DANGER
The tips of the tweezer are sharp. To avoid personal
injury or damage to the receptacle housing, be careful
when using the tweezer.
CAUTION
To avoid damage to the contact, make sure that the
tweezer tips straddle the contact locking window.
4. Slightly squeeze the tweezer, and slide the
tweezer tips along the locking ramp. Slowly pivot
the tweezer downward so that the endof the locking
ramp raises slightly, only enough to clear the
contact locking window. See Figure 2, Detail C.

CAUTION
Be careful not to over-extend the locking ramp. If the
end of the locking ramp is raised too much, it will NOT
returnto itsoriginal position; andthereceptacle housing
must be discarded.
5. While holding the locking ramp in position, gently
pull back on the wire until the contact is free. See
Figure 3. If the contact does not pull out freely, push
it back into the receptacle housing, and repeat the
extraction procedure.
CAUTION
DO NOT pull the wire in a harsh manner. If the locking
ramp is not raised enough to clear the contact locking
window, the locking ramp will be cut or sheared (see
Figure 3). If the locking ramp is cut or sheared, discard
the receptacle housing. The contacts may be removed
and re-used.
CAUTION
DO NOT raise the locking ramp to check for damage;
instead, after inserting a contact into that contact cavity,
pullback onthewire toensurethatthe lockingramphas
engaged the contact locking window. If the contact pulls
out, the locking ramp has been damaged.
4. REPLACEMENT AND REPAIR
The contacts, receptacle housing, and contact retainer
are not repairable. DO NOT used damaged or
