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 end of the locking ramp raises slightly, only enough to clear the contact locking window. See Figure 2, Detail C.

Rev B CAUTION Be careful not to over-extend the locking ramp. If the end of the locking ramp is raised too much, it will NOT return to its original position; and the receptacle 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, pull back on the wire to ensure that the locking ramp has 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 defective product. 5.
