Sealed Circular Receptacle for Harsh Environments
The Hirose LF07WBR-6P is a 6-position circular receptacle with male pins, part of the LF series, designed for applications requiring a rugged, sealed interconnect. The metal shell and bayonet lock provide a durable, vibration-resistant mate, while the IP67/IP68 rating means the mated pair is dust-tight and submersible — suited for outdoor telecom, industrial controls, and marine equipment where moisture or washdown is a concern. The 2 A per-contact current rating and 30 VAC / 42 VDC voltage limit place this squarely in signal-duty territory — it is not a power connector. Termination is via solder cups, so the installer solders wires directly into the contact cups — no crimp tool required. This makes it a practical choice for field repair, prototype runs, or low-volume builds where a crimp tool investment is not justified.
The IP67/IP68 rating is the defining feature of this connector. IP67 means it survives immersion in 1 m of water for 30 minutes; IP68 is a deeper, longer submersion test agreed between supplier and user. For a panel-mounted bulkhead receptacle with a rear-side nut, the seal works at the panel face — the O-ring compresses against the panel, not the threads. The shell finish is nickel, which provides a consistent ground path through the bayonet lock ring when mated.
Mating and Panel Mounting
This receptacle mates with the LF07WBR-6S, which is the 6-position female socket version of the same shell size 7. The bayonet lock gives a positive mechanical connection that resists vibration and accidental disconnection — the lock ring rotates and clicks into a detent, so the mate is confirmed by feel. The bulkhead mounting with a rear-side nut means the connector is secured from inside the panel, with the mating face protruding through the cutout. The shell size 7 insert accepts the 6 contacts in a circular pattern. The keyed orientation prevents mis-mating — the insert is rotationally keyed so the male pins only align with the female sockets in one position.
Comparison: LF07WBR-6P vs LF07WBR-3P
The LF07WBR-3P is the 3-position version of the same shell size 7 receptacle. The key difference is circuit count: 6 positions on the -6P vs 3 positions on the -3P. The -3P also carries a higher current rating of 5 A per contact and a higher voltage rating of 125 VAC / 175 VDC, because the lower pin density leaves more creepage distance between contacts.
