Rated for -25°C to 90°C operation, the PA66 housing handles the thermal range of an indoor industrial cabinet or consumer appliance enclosure. For a full harness build, order the contacts and the mating header (the YLP-series pin header) alongside this receptacle. The YLR-04VF and the YLR-06VF are identical in every dimension except position count: 4 positions vs 6 positions. Same 0.177\" (4.50 mm) pitch, same 2-row layout, same latch holder, same PA66 housing in white. The choice comes down to how many circuits your harness needs — 4 or 6. No difference in current handling per contact or environmental rating.","metaTitle":"JST YLR-04VF YL Series Receptacle Housing, 4 Pos, 4.50 mm","metaDescription":"JST YLR-04VF YL series 4-position receptacle housing, 4.50 mm pitch, latch holder, free-hanging crimp termination.
