What This Sealed Circular Connector Does
The Hirose HR30-6R-6P(71) is a 6-position male receptacle from the HR30 series, designed for panel-mount applications where a dust-tight and waterproof seal is required. It carries an IP67/IP68 rating, meaning it withstands immersion and high-pressure washdown — suited for marine electronics, industrial sensors, and medical equipment that see moisture or hose-down cleaning. The push-pull fastening lets you mate and unmate by hand without tools, while the keyed orientation prevents cross-plugging in multi-connector panels. The gold-plated mating surface (8.00 µin) gives reliable corrosion resistance across repeated mating cycles in humid or salt-spray environments. Termination is solder cup — you tin the wire and solder directly into the cup, no crimp tool required. Mounting is bulkhead-style with a rear-side nut, so the connector body stays fixed while the cable side mates to it.
How It Compares to Nearby Siblings
Both are active and interchangeable in the same shell — the contact material difference may matter for procurement if the BOM specifies brass vs copper alloy. For a higher per-circuit current, the HR30-6R-3P(71) drops to 3 positions but bumps the rating to 5 A per contact, trading channel count for power headroom. The direct mating half is the HR30-6R-6S(71), a 6-position female socket receptacle with the same shell and push-pull lock.
