Shielded 8-Position Right-Angle Receptacle for PCB Edge Mounting
The Hirose HR12-10RC-8SDL(71) is an 8-position shielded receptacle with female sockets, designed for through-hole right-angle mounting on a PCB. It belongs to the HR12 series, a compact circular connector family suited for signal and low-power interconnects in equipment where EMI containment matters. Key features include a snap-in fastening mechanism, board lock for secure PCB retention, and a ground feature that ties the shield to the board ground plane. This connector is used in applications like industrial control panels, test equipment, and medical devices where a shielded, keyed circular interface is needed in a right-angle board-mount format.
The 100VAC / 140VDC voltage rating sets the insulation class — fine for signal-level circuits and low-voltage DC power rails, but not for mains or high-voltage bus work. The tin contact finish is a practical choice for moderate mating cycles; tin oxidizes over time but wipes clean on insertion, so it holds up for occasional disconnect/reconnect in a controlled environment. The -15°C to 60°C operating range limits this connector to indoor or climate-controlled enclosures — it won't survive a freezer or a hot warehouse roof. The shielded construction means the shell is electrically continuous, so the ground feature can bleed shield current to the PCB ground plane — important for signal integrity in noise-sensitive designs.
