Q1: Are crimp terminals included inside the factory bulk packaging of part number 794954-2?
A: No. Part number 794954-2 refers exclusively to the empty plastic receptacle housing. The matching female crimp contacts must be selected and ordered as separate line items based on your specific wire gauge requirements.
Q2: Why is the 794954-2 classified as a 2-row connector when it only has 2 total positions?
A: The connector features a 2 x 1 matrix orientation, meaning it has 1 column and 2 rows. This vertical stacking layout minimizes the horizontal footprint on wire-to-board or wire-to-wire connections where space is constrained.
Q3: What are the strict limitations regarding wire insulation diameters for this VAL-U-LOK housing?
A: To ensure correct terminal insertion and secure retention within the nylon housing cavities, the wire insulation outer diameter must fall strictly within the range of 1.2 mm to 3.1 mm (0.047 in to 0.122 in).
