The 4-position count in a dual-row arrangement (2 rows) is a common configuration for small sensor and actuator harnesses where the circuit count is fixed. The white color aids visual inspection of the latch engagement and wire seating during harness assembly. ## Position Counts in the YL Series The YL series receptacle housings are available in several position counts at the same 0.177\" (4.50mm) pitch. The 4-position YLR-04V is the smallest dual-row option; the 6-position YLR-06V (and its VF variant) adds two circuits in the same row layout for harnesses that need more I/O. The pitch and latch style are identical across the family, so the same crimp terminal and mating header are used — only the cavity count changes.","metaTitle":"JST YLR-04V YL Series Receptacle Housing, 4 Position, 4.50mm","metaDescription":"JST YLR-04V YL series 4-position receptacle housing, 0.177\" (4.50mm) pitch, free-hanging, crimp termination.
