The **W2SP-1C3-R/N** is a specific model of an **Industrial Joystick** or **Micro-joystick**, commonly manufactured by companies like *Sakae* or similar industrial control specialists. These devices are designed for precision control in medical equipment, industrial machinery, and CCTV systems. --- ## Technical Specifications & Electronic Components The "W2SP-1C3-R/N" code refers to a multi-axis controller with specific electrical characteristics. Below is a breakdown of its primary electronic parts: ### 1. The Sensing Element (Potentiometers) The core electronic components are **Conductive Plastic Potentiometers**. Unlike standard carbon pots, these offer high resolution and a long life cycle. | Feature | Specification (Typical) | | :--- | :--- | | **Total Resistance** | 10kΩ (±15%) | | **Independent Linearity** | ±3% | | **Electrical Angle** | Approx. 40° to 50° | | **Power Rating** | 0.1W | ### 2. Axis Configuration The "W" and "2" in the prefix usually denote the structural design: * **X & Y Axis:** Controlled by two independent potentiometers mounted at 90-degree angles. * **Z-Axis (Optional):** Some models in this series include a "twist" function on the handle for a 3rd axis. ### 3. Switch Mechanism (1C3) The "1C3" suffix typically refers to the **Micro-switch** integrated into the unit: * **Type:** SPDT (Single Pole Double Throw). * **Function:** Often used as a "deadman switch" or a "top-button" trigger. * **Rating:** Usually rated for low voltage/low current logic signals (e.g., 5V DC). --- ## Wiring and Connections The device uses color-coded wires to represent the different axes and the push-button switch. ### Internal Circuit Diagram (Simplified) ```mermaid graph LR A[VCC +5V] --- B(Potentiometer X) A --- C(Potentiometer Y) B --- D[Signal X Out] C --- E[Signal Y Out] F[GND] --- B F --- C G[Switch Terminal] --- H[Button Out] ``` --- ## Part Number Breakdown | Segment | Meaning | | :--- | :--- | | **W2SP** | Series identifier (Miniature Industrial Joystick) | | **1C3** | Indicates 1 Micro-switch with specific terminal/contact type | | **R/N** | **R**: Spring Return to center / **N**: Dust-proof rubber cover (Nippon/Standard) | --- ## Typical Applications 1. **Medical Imaging:** Moving C-arms or ultrasound probes. 2. **Robotics:** Manual override for robotic arms. 3. **CCTV:** Pan-Tilt-Zoom (PTZ) camera operations. 4. **Heavy Machinery:** Remote control consoles for cranes or lifts.
