MCXJ vs MCXJR connector from SMA for Japan ISDB-T MCXP

In the naming convention of MCX connectors:

1. MCXJ: Represents the male connector (Plug), featuring a center pin and a smooth outer sleeve (designed to be inserted into the female connector). So some client also call MCXJ to MCXP.
2. MCXJR: Represents the female connector (Jack), featuring a center receptacle (socket) and an outer sleeve with spring-loaded contacts (designed to accept the male connector).

Key Differentiators:

• Suffix “R”: Typically denotes “Reverse,” indicating a gender reversal from the base model. If MCXJ is male, MCXJR becomes female.
• Physical Features:
  • Male (MCXJ): Protruding center pin; smooth outer sleeve.
  • Female (MCXJR): Recessed center receptacle; outer sleeve with spring contacts for secure mating.

Notes:

• Naming may vary slightly between manufacturers; always verify with the product datasheet.
• MCX connectors are push-on (non-threaded) types—ensure proper alignment and gentle pressure during mating.

Summary: MCXJ is male (Plug), MCXJR is female (Jack).
