Frequently Asked Questions
What are the enclosure panel cutout specifications and maximum thickness for this M12 C-code male plug?
This M12 C-code male connector requires a D-shaped panel cutout with an anti-rotation flat width of 13.5mm (+0.1/-0mm). The borehole diameter is Ø15.3mm (+0.1/-0mm) for the PG9 thread variant and Ø16.1mm (+0.1/-0mm) for the M16x1.5 thread variant, supporting a maximum enclosure panel thickness of 3.0mm.
What is the primary difference between M12 A-Code and C-Code connectors in industrial equipment?
M12 C-Code connectors utilize a dual keyway polarization specifically engineered for AC sensor, actuator, and power-switching circuits, preventing accidental cross-mating with standard single-keyway A-Code DC sensors or D-Code Ethernet devices.
What electrical ratings and pin counts are supported by this M12 C-code PCB plug?
According to Table 1, the 3-pin and 4-pin C-code configurations deliver up to 4A at 250V DC, whereas the 5-pin configuration supports 2A at 60V DC and the 6-pin configuration provides 2A at 30V DC, all compliant with IEC 61076-2-101.
How does the rear mount design achieve IP67 environmental sealing?
The receptacle achieves IP67 ingress protection through a black silicone O-ring seated against the exterior panel wall combined with complete black epoxy resin potting encapsulating the rear PCB solder pins, operating reliably across a temperature range of -40°C to +80°C.
Overview and Application Notes
The M12 C-Code Male Rear Panel Mount Device Connector Plug is engineered with straight through-hole DIP PCB solder pins for industrial AC actuator controls, dual-keyway sensors, and field device bulkhead interfaces. Designed in compliance with IEC 61076-2-101 standards, this connector series offers 3-pin, 4-pin, 5-pin, and 6-pin configurations with PG9 or M16x1.5 panel mounting threads. Featuring an overall body length of 19.8mm, high-grade nickel-plated copper alloy housing, and rear black epoxy potting, it ensures dependable IP67 waterproof ingress protection in harsh industrial automation environments.
