The zinc housing with silver finish mounts to a panel or bulkhead, and a dust cap is included to protect the ferrule when the port is unused. The ferrule alignment sleeve is glass-filled polyphenylene sulfide (PPS), rated UL94 V-0. Operating temperature spans -20°C to 75°C. ## Sourcing Reality — Obsolete Status The 501381-1 is marked Obsolete by the manufacturer. No official replacement order code is listed. If you are designing a new panel, consider a current-production ST simplex coupler from the same interface family to avoid an orphan port on the shelf. Both adapter ends are ST receptacles — this coupler mates with any standard ST connector. The simplex configuration handles one fiber channel per coupler.","metaTitle":"501381-1 ST Simplex Coupler, Multimode, Panel Mount","metaDescription":"501381-1 ST simplex multimode coupler, panel mount bulkhead, -20°C~75°C, UL94 V-0.
