This is the receptacle crimp housing of Molex classic PicoBlade™ 1.25mm connector system, single row, 15-circuit (15P), natural white PBT plastic shell. It works with separately purchased female crimp terminals to complete cable-side wire harness assembly, and mates with PicoBlade series PCB headers to realize compact wire-to-board connection, or matches plug housing for wire-to-wire interconnection.
Built-in friction locking structure reliably retains crimp terminals inside housing to prevent terminal back-out under vibration. Polarized housing design avoids incorrect mating with PCB headers. Ultra-small 1.25mm center pitch greatly saves equipment internal layout space, ideal for low-current signal transmission in compact electronic equipment.
