PJ521 orders connector type, contact count, plating, colour, material and support ears. Its body measures 12.2mm wide, 12.85mm deep and 14.4mm high. The drawing shows both ear configurations. Tail diameter is Ø0.45mm with a 3.3±0.3mm projection. Section references are 2.54±0.1mm and 2.3±0.1mm; the locating-line-to-body reference is 6mm. The top detail identifies 3.35mm and 2.2mm offsets.
PJ521A orders connector type, contact count, plating, colour and material. Overall width is 15.75±0.15mm, depth is 20.57±0.15mm and height is 16±0.15mm. The body detail also shows a 13.21±0.15mm width and 15mm section height. Tails project 4-4.5mm; section contact-row and locating references are 2.54±0.1mm and 8.89±0.1mm.
PJ521B orders connector type, contact count, plating, colour and support ears. The opening-face outline is 15.7mm wide by 15.88mm, with a 13.45mm inner width reference. Body length along the section is 16.38mm, and the tail projection is 3.3mm. Its drawing keeps the 2.54mm row spacing and 8.89mm locating reference separate from the 1.02mm mating-contact pitch.
PJ521C orders connector type, contact count, plating and colour. Body width is 13.2mm, depth is 18mm and height is 11.65mm. Contact-face width is 9.88mm; section opening references are 6.75mm and 6.83mm. Tail and locating-post projections are 3.30mm, with a separate 1.65mm contact-support reference. The locating line is 7.88mm from the body end.
