3-Position YL Receptacle Housing
It uses a 4.50 mm pitch, giving each circuit enough spacing for moderate current without crowding the crimp terminals. The housing is free-hanging (in-line), mates with the corresponding YL series pin header, and secures the connection with a latch holder that locks audibly when fully seated.
Fit and Termination
This is a crimp-style housing — the contacts are ordered separately (JST part number SYF-01T-P0.5A or equivalent YL crimp terminal). The single-row, 3-position layout accepts male pin contacts, and the white PA66 body provides a -25°C to 90°C operating range.
Position Count Options
The YL series offers the same 4.50 mm pitch and latch-lock design in 2-position (YLR-02VF), 4-position (YLR-04VF), and 6-position (YLR-06V) variants. The 3-position YLR-03VF sits between the 2- and 4-position siblings — useful when a harness needs exactly three circuits and a 4-position housing would leave an unused cavity that collects debris.
