The end cap and ferrule capture the cable jacket and braid during the crimp cycle; the insulator centers the dielectric and center contact. Having all four pieces in one BOM line simplifies kitting — no separate ferrule or insulator to source. The connector accepts RG-174, RG-188A, RG-316, LMR-100, and M17/119-RG174 — all 50 Ohm cables. The center contact is crimped, and the shield is crimped via the ferrule.","metaTitle":"Amphenol RF 919-387P-51A MCX Plug, 50 Ohm, 6 GHz, Crimp","metaDescription":"Amphenol RF 919-387P-51A MCX plug, male pin, 50 Ohm, 6 GHz max, crimp termination.
