Equipment designers often need to route main power together with low-current control or communication circuits. A combined power and signal connector can reduce the number of separate interfaces while keeping the system connection point easier to organize.
Why one interface can simplify the system
Using separate connectors for power and signals can add routing complexity, panel openings and assembly steps. A combined configuration can support a more compact interface when the system needs power plus auxiliary circuits at the same connection point.
Catalogue-backed mixed-contact configurations
CONNIXTECH’s self-locking catalogue includes an M16 2+4PIN configuration listed at 10A+3A / 60V and an M20 3+9PIN configuration listed at 16A+3A / 300V+60V. These entries demonstrate the value of defining power and signal requirements together rather than selecting a power-only connector first and adding a separate signal interface later.
Map each circuit before selecting the arrangement
Before selecting a combined connector, identify which circuits are power, control, monitoring or communication. Review the required contact count, current level, operating voltage and cable construction. This helps ensure the connector arrangement supports the real system architecture.
Review cable and enclosure integration
The connection should fit the enclosure, cable outlet direction and service process. Consider cable diameter, bend allowance, strain relief and the route to internal terminals or boards. For a combined power and signal connection review, browse the Product Centre or send an inquiry.
