12-Position Sealed Circular Plug for Low-Voltage Power and Signal
The Hirose HR30-7PB-12S is a 12-position (power) circular plug from the HR30 series, designed for applications where a compact, push-pull locking connector must survive wet or dusty environments. It carries an IP67/IP68 rating — dust-tight and submersible — making it a fit for marine electronics, medical equipment, and industrial sensors that see washdown or occasional immersion. The shell size 7 body houses 12 female sockets rated 2 A per contact at 30VAC or 42VDC, with gold-plated mating surfaces for corrosion resistance over repeated connect cycles.
Push-Pull Locking with Built-In Backshell and Strain Relief
The push-pull fastening mechanism lets you mate or unmate the connector with a single axial pull — no coupling nut to turn, which matters in tight cable bundles or panel cutouts where wrench clearance is zero. The housing comes with an integrated backshell and strain relief, so the cable exit is protected against pull-out and flex fatigue without ordering a separate accessory. The keyed orientation prevents cross-mating with other HR30 insert arrangements.
Solder Cup Termination — Field-Terminable, No Crimp Tool
Termination is solder cup — each of the 12 contacts has a cup that accepts a tinned wire end, soldered in place. This is a field-service-friendly approach: you don't need a specific crimp tool or die set, just a soldering iron and heat-shrink. The trade-off is that consistent solder fill and strain relief are up to the assembler; a cold joint or oversized solder blob can compromise the IP seal at the wire exit.
IP67/IP68 and UL94 V-0 — Sealed for Washdown, Flame-Rated for Enclosures
The mated connector pair is rated IP67/IP68 — dust-tight and submersible.
Mating Connector and Cross-Reference Notes
The mating half for this plug is a HR30-series jack (female receptacle) with the same shell size 7 and 12-position insert arrangement — for example, the HR30-8J-12S(71) is a documented jack that shares the same 12 (power) position count, 2 A rating, and IP67 rating. The HR30-7P-12S(71) is a functionally similar plug variant with a slightly different cable opening range (0.244" to 0.276" / 6.20 mm to 7.00 mm) and a documented contact finish thickness of 8.00 µin (0.203 µm) on the mating side. For a 6-position alternative in the same shell size, the HR30-6PB-6S drops to 6 power contacts and carries a higher voltage rating of 100VAC, 140VDC.
