Rated for 200 mating cycles, it is suited for test equipment, industrial networking, and legacy telecom links where the FSMA interface is still in service. ## Construction and Cable Fit The body is copper alloy with nickel plating, the ferrule is stainless steel, and the boot is black. Accepts a 3.1 mm cable diameter — a specific fit, not a range. ## Lifecycle: Obsolete — Sourcing the 504566-7 The 504566-7 is officially listed as Obsolete. No direct replacement or cross-reference is recorded in the TE OPTIMATE series. For a potential alternative, a review of the FSMA interface standard and the specific cable diameter is recommended.","metaTitle":"TE Connectivity 504566-7 FSMA Plug, Multimode, Obsolete","metaDescription":"TE Connectivity 504566-7 OPTIMATE FSMA plug, multimode, 3.1mm cable, 200 mating cycles.
