Xmost M12 B-coded male rear mount PCB connector links an external PROFIBUS cable assembly to the circuit board inside industrial communication equipment. The male B-coded interface accepts a compatible female cable connector, with straight rear contacts providing PCB dip-solder termination.
Designed for rear fastened installation, this M12 panel mount connector suits enclosures with a defined panel-to-board position. Its rear mount outline differs from the front mount version and should be used when checking housing clearance and PCB placement.
Three panel mounting threads are available. Grounded or ungrounded construction and shielded or unshielded options allow the connector to be specified for the equipment’s fieldbus interface.
Key Features
- Rear fastened construction: For equipment housings designed around a rear mount panel connector.
- Male B-coded connection: Mates with compatible 5-pin M12 B-coded female PROFIBUS cable connectors.
- Direct PCB termination: Straight insertion contacts support dip soldering to the internal board.
- Multiple mounting threads: Choose M12 × 1.0, PG9 or M16 × 1.5.
- Grounding and shielding options: Match the connector construction to the equipment design.
- Listed 4 A / 60 V ratings: Electrical specifications for the 5-pin configuration.
