Technical details and manufacturing context for Electrical Connection Head

Definition
The electrical connection head is a critical sub-component of sensors and probes that serves as the termination point for electrical wiring. It houses the terminals, connectors, or pins that establish the electrical pathway between the sensing element and the external measurement, control, or data acquisition system. Its primary role is to ensure a secure, reliable, and often environmentally sealed connection for signal transmission and/or power supply.
Working Principle
The connection head functions by providing a physical and electrical interface. Internal terminals are connected to the sensor's internal leads. External cables are then attached to these terminals via screw clamps, spring clamps, plug connectors, or solder points. This creates a continuous conductive path, allowing electrical signals (e.g., voltage, current, resistance) generated by the sensor to be transmitted out, or allowing power to be supplied to the sensor.
Common Materials
Thermoplastic (e.g., PBT, PPS), Stainless Steel, Brass, Nickel-Plated Brass
