MJS415A jumper and pin connector assembly
This version combines one DS1021 connector with one DS1027 jumper component. The assembly has 2.54mm pin spacing and square pin sections of 0.64mm × 0.64mm, with the drawing marking a ±0.05mm pin-size tolerance. The pin extension is 3.00mm; overall axial dimensions are 11.5mm to the upper edge and 10.5mm to the inner reference surface.
