The Hirose LF07WBR-6S is a 6-position circular receptacle with female sockets, part of the LF series. The zinc alloy shell with nickel finish and PPS insert handles industrial and telecom environments where moisture or washdown is a concern. Solder cup termination means you can re-pin it on site with a soldering iron, no crimp tool required.
Field Repair and Wiring
Solder cup contacts let you terminate wires directly — strip, tin, and solder into the cup. The 2 A per-contact rating and 30 VAC / 42 VDC voltage ceiling mean this is a signal and low-power control connector, not a power feed. The bayonet lock mates with a quarter-turn and holds under vibration — what's really failing here is usually a corroded contact in a lesser-sealed shell, not the lock itself.
This receptacle mates with the LF07WBR-6P, a 6-position plug with male pins in the same shell size 7. Both use the same bayonet lock and IP67/IP68 seal — the pair crosses into the harness you've got if you're already running LF series. The bulkhead - rear side nut mounting secures it through a panel cutout; the O-ring seals at the panel face, not the threads.
