M12 Y-coded male rear mount socket connects a compatible external hybrid cable to separate signal and power wiring inside the equipment housing. Select the rear fastened version when the panel design provides access and clearance for the rear mounting hardware.
The Y3 arrangement contains four signal contacts and two power contacts. Y4 contains four signal contacts and four power contacts. Both use a 0.5 A signal-contact rating, while their power-contact ratings are 12 A and 6 A respectively.
Choose an unwired M12 hybrid solder socket for termination during assembly or the 0.3 m pre-wired version for routing to internal connection points. Confirm the configuration, mounting thread and mating connector together.
Key Features
- Hybrid signal and power connection: Combines separate circuits in one M12 panel interface.
- Rear fastened installation: For equipment housings designed around a rear mount receptacle.
- Male Y-coded interface: Connects to a matching Y3 or Y4 female connector.
- Y3 configuration: Four signal contacts plus two power contacts, with a 12 A power-contact rating.
- Y4 configuration: Four signal contacts plus four power contacts, with a 6 A power-contact rating.
- Shielded construction: As listed for this product version.
- Solder termination: Available unwired or with 0.3 m leads.
- PG9 or M16 mounting: Two panel thread options.
