It carries a shell size 10 insert, gold-plated mating contacts at 8.00µin thickness, and a bayonet lock for quick quarter-turn mating. Rated 10 A per contact at 125 VAC/DC, it handles sensor power and signal lines in industrial and telecom cabling where water ingress is a real risk. ## Sealing and Mounting Reality The IP67/IP68 rating means the mated pair survives temporary submersion — the O-ring seals at the panel face, not the threads. The bulkhead - rear side nut mounting lets you install the receptacle from outside the enclosure and tighten the nut from behind, which keeps the panel gasket compressed evenly. The bayonet lock gives a positive mechanical mate that won't back off under vibration the way a push-pull can. Solder cup termination means field wiring with a soldering iron — no crimp tool required, but each of the 4 contacts gets individually soldered, so assembly time is higher than a crimp-and-insert design. ## Comparing the 4-Position Male to Its Siblings The LF10WBR-4P is the 4-position male-pin version. Its counterpart, the LF10WBR-4S, is the same shell size 10, same 10 A rating, same IP67 seal — but with female sockets instead of male pins. If your harness terminates in a female plug, the LF10WBR-4S is the panel-mount match. The LF10WBR-12P shares the same shell size 10 but packs 12 positions, which drops the per-contact current to 2 A and the voltage to 30 VAC / 42 VDC — the pin density trades power capacity for more signal lines in the same panel cutout.","metaTitle":"Hirose LF10WBR-4P Receptacle, Male Pins, 4-Position","metaDescription":"Hirose LF10WBR-4P circular receptacle, 4 male pins, gold-plated contacts, 10 A, 125 VAC/DC, IP67/IP68 sealed, solder cup termination.","metaKeywords":null},"attributes":{"series":"LF","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Circular Connectors","Circular Cable Assemblies"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Color":"Silver","Series":"LF","Package":"Tray","Features":"-","Shielding":"-","Orientation":"Keyed","Termination":"Solder Cup","Applications":"Industrial, Telecommunications","Shell Finish":"Nickel","Cable Opening":"-","Mounting Type":"Panel Mount","Connector Type":"Receptacle, Male Pins","Fastening Type":"Bayonet Lock","Product Status":"Active","Shell Material":"Zinc Alloy","Voltage Rating":"125VAC/DC","Insert Material":"Polyphenylene Sulfide (PPS)","Shell Size, MIL":"-","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Mounting Feature":"Bulkhead - Rear Side Nut","Primary Material":"Metal","Ingress Protection":"IP67/IP68 - Dust Tight, Waterproof","Base Product Number":"LF10WBR","Number of Positions":"4","Shell Size - Insert":"10","Current Rating (Amps)":"10A","Operating Temperature":"-25°C ~ 85°C","Contact Finish - Mating":"Gold","Backshell Material, Plating":"-","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"8.00µin (0.203µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.5700","priceTiers":[{"qty":1,"price":"$10.57000","currency":"USD"},{"qty":10,"price":"$9.51300","currency":"USD"},{"qty":25,"price":"$8.96120","currency":"USD"},{"qty":60,"price":"$8.73150","currency":"USD"},{"qty":120,"price":"$8.50167","currency":"USD"},{"qty":240,"price":"$7.58258","currency":"USD"},{"qty":480,"price":"$7.12302","currency":"USD"},{"qty":960,"price":"$6.29583","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d25cff7ae19175f493c92e5e69c51ad5.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/LF10WBR-4P/alternatives.json"},"ai":{"faq":[{"question":"What connectors mate with LF10WBR-4P?","answer":"The LF10WBR-4P is a male-pin receptacle.
