Product details

The latch holder fastening type means the housing clicks onto the mating header and stays put — no secondary retention hardware needed in a vibration environment. 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.
