INTRODUCTION AMP* AMPINNERGY WTB (wiretoboard} connectors consist of Plug Housing 556879-[ ], Right-Angle Receptacle 556882-] ], and Vertical Receptacle 556881-[ ]. The plug housing accepts two sizes (18-16-14 and 12-10} of dual-beam contacts crimped onto stranded copper wire sizes 18-10 AWG. The receptacle contains preinstalled solder type contacts for pc (printed circuit) board application. Read these instructions thoroughly before starting assembly. For detailed application requirements, refer to AMP Application Specification 114-6044. Alf dimensions on this sheet are in meirie unils ad {with U.S. customary unils in brackets}. Reasons for reissue of this instruction sheet are provided in Section 4, REVISION SUMMARY. 2 DESCRIPTION (Figure 1) The connectors feature mounting flanges for attaching to the pc board and panel. The connectors are polarized to provide error-free mating, and the locking features prevent the connectors from accidentally disengaging. 3. INSTALLATION 3.1. Crimping Contact Refer to Figure 2 for wire size and dual-beam contact part numbers. Grimp each contact using the appropriate strip length and tooling according to AMP instruction sheet 408-3198. The crimped contacts must meet inspection requirements according to 408-3198. WIRE SIZE RANGE (AWG) CONTACT 18-14 556883-2 12-10 556880-2 Figure 2 3.2. Contact Insertion 1. Align crimped contact with the appropriate contact cavity in the plug housing so that the top of the contact slides against the internal housing latch. Refer to Figure 3. 2. Insert the contact until it bottoms in the housing. Contact must latch under the edge of the internal housing latch. 3. Pull back on wire to verify that the contact retains in housing.
