Connection Terminal: Rated Voltage Up to 600V AC/DC

Component Specifications

Definition

A connection terminal is a critical electromechanical component within speed control interfaces, designed to establish and maintain electrical continuity between conductors, cables, or wires and the control circuitry. It ensures low-resistance, vibration-resistant connections that facilitate signal integrity and power transmission for precise motor speed regulation in industrial machinery.

Working Principle

The terminal operates by providing a clamping mechanism (such as a screw, spring, or insulation displacement contact) that mechanically secures a conductor. This creates a metal-to-metal contact interface, allowing electrical current or control signals to pass from the connected wire to the terminal block or PCB, thereby integrating the conductor into the speed control circuit.

Materials

Terminal body: PA66 (Polyamide 66) or PBT (Polybutylene terephthalate) for insulation; Contact elements: Copper alloy (e.g., brass or bronze) with tin or silver plating for corrosion resistance and conductivity; Clamping screws: Steel with zinc plating.
