Shielded 8-Position Right-Angle Receptacle for Panel-Mount Signal Runs
It belongs to the HR212 series of circular connectors, which are built for signal-level interconnect in equipment where EMI control and a positive snap-in mate matter more than high pin count. The shell is shielded and carries a ground feature, so the shield path ties into the board ground plane through the solder tails — a detail that saves a separate ground wire in the harness. The 8-position count matches a common 8-conductor signal cable, and the keyed orientation ensures the plug only goes in one way — useful in multi-connector panels where a mis-mated pair would short a control line. The snap-in fastening holds the pair together without a threaded coupling ring, so field removal is tool-less.
Rated 100VAC / 140VDC, this connector sits in the signal-voltage range — think 24 VDC control loops, sensor networks, or low-voltage DC power distribution inside an enclosure. It is not a mains-power connector. Gold at that thickness handles hundreds of cycles without the fretting corrosion you get with tin on tin in low-current signal circuits.
Mounting and Shielding — Board Layout Notes
That orientation is standard for panel-mount receptacles where the cable enters from the side of the enclosure. The shielded shell with tin finish and the ground feature mean the PCB footprint should include a ground-plane connection to the shell solder tabs — without it, the shield is floating and the EMI benefit is lost.
Comparing the 8-Position to the 10-Position HR212 Sibling
The closest same-series alternative is the HR212-10RC-10SDL(74), a 10-position receptacle in the same HR212 family. Both share the 100VAC/140VDC rating, gold-plated contacts, shielded shell, and keyed snap-in mating. The decision between them is purely positional: 8 circuits vs 10 circuits.
