M12 Waterproof Cable Connector Industrial Robot A Code 5 Core PCB Plug Connector Socket
The M12 On-Site Terminable Connector (also known as an M12 field-wireable plug, M12 attachable connector, or M12 screw-terminal plug) is a cable-end component that can be assembled in the field, serving as the counterpart to a standard factory-overmolded M12 cordset. Rather than buying pre-made cables with predetermined lengths, you supply your own cable, strip the insulation, secure the wires into the contact carrier using a screwdriver (or via soldering/crimping), and fasten the connector body onto the cable with an M12×1.0 threaded locking ring.
It meets the requirements of IEC 61076-2-101 (sensor/actuator) and IEC 61076-2-109 (X-coded Ethernet), is compatible with any standard M12 panel receptacle or mating plug, and attains IP67 sealing when tightened with the appropriate O-ring and cable gland.
This solution is ideal for maintenance teams, custom machine builders, and system integrators who cannot wait 2-4 weeks for tailored overmolded cordsets or need to repair damaged sensor cables quickly on the shop floor.
- Cut any cable to precise lengths on site—eliminates fixed length limitations and leftover cable remnants
- Quick field repairs—restore damaged sensor cables in minutes instead of waiting for replacements
- IP67 sealed when mated with dual O-rings for protection against dust, oil mist, coolant spray, and immersion
- Keying prevents wrong connections with mechanically distinct keyways for various applications
- Multiple current ratings: 4A (2-5 pin), 2A (6-8 pin), 1.5A (12/17 pin), with T-code supporting up to 12A/60V DC
- Flexible termination options: screw-clamp, solder, or insulation displacement without specialized tools
- Available in straight or right-angle configurations with plastic or metal housing options
- Reduced inventory requirements compared to pre-molded cordsets

Versus pre-molded M12 cordsets: No factory lead time for custom lengths, 50-60% fewer stock-keeping units, field-repairable, no wasted cable offcuts
Versus open screw-terminal plus heat shrink: Coded keying prevents miswiring, IP67 sealed, vibration-proof threaded lock, industrial mating life
Versus low-cost generic field plugs: IEC-standard dimensions mate with every major brand, gold contacts resist corrosion in humid environments
Versus bulkhead-only M12: Cable-end design—free-hanging, drag-chain capable, not restricted to panel mounting
- Factory automation: proximity and photoelectric sensors, valve islands, IO-Link masters, conveyor encoder cables
- Industrial Ethernet: D-code 100 Mbps PROFINET/EtherNet/IP, X-code Gigabit camera and controller drops
- Machine building and retrofit: custom machinery, laboratory automation, semiconductor handlers where standard cordset lengths do not fit
- Field repair and maintenance: cut and re-terminate damaged sensor cables on the production floor
