RoHS compliant per the listing. ## 50-Position Density and Termination At 50 positions in two rows, this plug packs a lot of signal lines into a compact footprint — typical for I/O harnesses in industrial controls, test equipment, or medical devices where every millimeter counts. The solder eyelet termination means each wire is hand-soldered into a cup, giving the assembler direct control over the joint quality. Compare that to an IDC termination like the DX31A-80P(50) in the same DX family: IDC punches through insulation for mass-termination on ribbon cable, faster for production but harder to rework. Here, the solder eyelet is the right choice if you're building a harness with discrete wires and want the option to replace a single contact later. ## Sourcing and Status No official second-source cross-reference exists in the evidence, but the DX series includes other position counts and termination styles (like the DX31A-80P(50) with IDC or the DX40M-26P with solder eyelets at 26 positions) if the BOM allows a position change.","metaTitle":"Hirose DX40-50P(55) Miniature High Density Plug, 50 Position","metaDescription":"Hirose DX40-50P(55) Miniature High Density (HD) plug, 50 positions, 2 rows, gold contacts, solder eyelet termination, free hanging.
