The contacts are not included in this housing — you order the male pin crimp terminals separately and stuff them in after crimping. ## Mating Half and Terminal Reality This plug housing mates with a VAL-U-LOK receptacle header of the same 4.20mm pitch and 4-circuit count — the locking ramp on the plug engages the matching ramp on the receptacle side. The male pin contacts are crimp-terminated to the wire, then inserted into the housing cavities. Because the contacts are not included, the BOM needs a separate line for the terminals (TE part number for the pin contact, typically the 1-1703532 series or equivalent in the VAL-U-LOK family). The housing accepts the standard VAL-U-LOK crimp terminal, which handles 20-16 AWG stranded wire in the standard current range for the series. No secondary TPA retainer on this single-row version — the primary latch in the housing cavity holds the terminal.","metaTitle":"TE 2029177-4 VAL-U-LOK Plug Housing, 4 Pos, 4.20mm","metaDescription":"TE 2029177-4 VAL-U-LOK 4-position plug housing, 4.20mm pitch, locking ramp, white PA6.
