Product Specifications

Technical details and manufacturing context for Power & Signal Connectors

Definition
Power & Signal Connectors are critical electrical interface components within servo motor systems that facilitate the transmission of high-current power for motor operation and low-voltage control signals for precise positioning and feedback. They ensure reliable electrical connections between the servo driver and motor while protecting against environmental factors like vibration, moisture, and electromagnetic interference.
Working Principle
These connectors establish secure electrical pathways through mating pin/socket contacts. Power contacts carry high current from the driver to the motor windings, while signal contacts transmit control commands (position, velocity, torque) and receive feedback signals (encoder data, temperature). Proper mating ensures low-resistance connections and maintains signal integrity through shielding and proper grounding.

Frequently Asked Questions

What are the key benefits of using copper alloy contacts in power and signal connectors?

Copper alloy contacts provide excellent electrical conductivity, corrosion resistance, and mechanical durability, ensuring reliable power transmission and signal integrity in demanding industrial environments.

How do these connectors ensure secure connections in machinery applications?

Our connectors feature robust locking mechanisms and strain relief components that prevent accidental disconnection and protect against vibration, shock, and cable stress common in machinery operations.

What plating options are available and how do they affect performance?

We offer nickel or gold plating on contacts. Nickel provides good corrosion resistance at lower cost, while gold plating offers superior conductivity and oxidation resistance for critical signal transmission applications.

Can I contact factories directly on CNFX?
