Xmost M12 B-coded female front mount PCB socket provides a panel interface for PROFIBUS equipment and industrial fieldbus modules. It accepts a compatible M12 B-coded male cable connector and connects to the internal circuit board through straight PCB solder contacts.
This front fastened M12 panel mount socket combines a threaded external cable connection with board termination inside the enclosure. PG9 and M16 × 1.5 panel mounting options accommodate different housing designs.
The 5-pin B-coded connector is available with grounded or ungrounded construction and optional shielding. Specify grounding and shielding separately to match the fieldbus equipment’s connection requirements.
Key Features
- 5-pin PROFIBUS interface: B-coded female connection for compatible industrial fieldbus cable assemblies.
- Front mount construction: Front fastened panel installation with PCB contacts behind the enclosure.
- PCB dip-solder termination: Straight insertion contacts connect the socket to the equipment’s circuit board.
- Two panel thread options: PG9 or M16 × 1.5 mounting, with an M12 × 1.0 mating interface.
- Grounding and shielding choices: Grounded/ungrounded and shielded/unshielded versions.
- Listed electrical ratings: 4 A rated current and 60 V rated voltage.
