The Hirose HR10A-7R-6PB(73) is a 6-position, panel-mount receptacle with male pins, part of the HR10A series of push-pull circular connectors. It uses a keyed orientation to prevent mis-mating, and the push-pull fastening allows quick connect and disconnect without tools.
Sizing the Contact Rating for Your Circuit
Each contact is rated 2 A — that is a signal-level current, not bus-level power. The 2 A per contact, combined with the 100VAC / 140VDC voltage rating, tells you this connector is meant for low-power signal or control circuits, not a main DC rail.
Mating and Mounting Details
This receptacle mounts through a bulkhead panel using the rear-side nut (shell size 7). The push-pull latch means the mating plug simply pushes in to engage and pulls out to release — no screw threads or bayonet lock. The keyed shell ensures the plug only goes in one orientation, so you won't accidentally reverse the wiring. Mates with the corresponding HR10A series plug (male pins on this side, so the plug carries female sockets).
How It Compares to Nearby Siblings
Compared to the HR10A-7R-4PB(73) (4 positions, same shell size 7, same 2 A rating), the 6-position version gives you two more circuits in the same panel cutout. If you need gold rather than silver on the mating contacts, the HR10A-7R-6PB(74) swaps to 8.00 µin (0.203 µm) gold plating — better for environments with more corrosive atmospheres or higher mating cycle requirements.
