The **KPE-55-R** is a specific electronic component commonly used in industrial automation, robotics, and CNC machinery. It is primarily identified as a **Circular Connector** or a **Limit Switch/Sensor Component**, often associated with brands like **Koganei** or specialized electronics manufacturers. Below is a breakdown of its technical specifications and electronic characteristics. ### 1. General Specifications The KPE-55-R is typically designed for high-durability environments where precision signal transmission is required. | Feature | Description | | :--- | :--- | | **Component Type** | Circular Connector / Proximity Switch Accessory | | **Connection Type** | Multi-pin (usually 5-pin configuration) | | **Housing Material** | Nickel-plated brass or robust plastic | | **Mounting Style** | Panel Mount or Threaded (M12/M18 standard) | | **Environmental Rating** | Often IP65 or IP67 (Dust/Water resistant) | --- ### 2. Electronic Characteristics In a typical circuit, the KPE-55-R functions as an interface between a sensor and a controller (PLC). * **Voltage Rating:** Usually rated for **10V to 30V DC**, standard for industrial control systems. * **Current Capacity:** Designed for low-current signal transmission (typically **< 200mA**). * **Contact Resistance:** Extremely low (milliohms) to ensure signal integrity for sensors. * **LED Indicator:** Often includes a built-in LED (Red/Green) to indicate power status or signal actuation. --- ### 3. Pinout Logic (Common 5-Pin Standard) If used as an M12-style connector interface, the internal wiring generally follows this logic: ```json { "Pin 1": "Brown (+VCC)", "Pin 2": "White (NC - Normally Closed)", "Pin 3": "Blue (GND/0V)", "Pin 4": "Black (NO - Normally Open / Signal)", "Pin 5": "Gray (Functional Earth/Shield)" } ``` --- ### 4. Typical Applications The "R" suffix often denotes **RoHS compliance** or a specific **Right-angle** orientation. 1. **Pneumatic Cylinders:** Used to detect the position of a piston. 2. **CNC Tool Changers:** Provides feedback on whether a tool is locked in place. 3. **Safety Interlocks:** Ensures a machine guard is closed before operation. ---
