The **KMMLS-CB2-R** is an industrial-grade control component, primarily categorized as a **Limit Switch** or **Positioning Sensor** often used in heavy machinery, conveyor systems, or automated production lines. Below is an explanation of its electronic and mechanical parts. --- ## 1. Core Component Breakdown | Component | Description | Function | | :--- | :--- | :--- | | **Contact Block** | The internal switching mechanism. | Bridges or breaks the electrical circuit. | | **Actuator (R-Type)** | Typically a roller lever or rod. | The physical part that touches the moving object. | | **Housing/Body** | Die-cast metal or reinforced polymer. | Protects internal electronics from dust and moisture (IP Rating). | | **Terminals** | Screw or plug-in connections. | Points where external wiring is attached. | --- ## 2. Electrical Specifications While specific ratings can vary by sub-manufacturer (like KACON or similar industrial brands), the standard electrical characteristics for this series typically include: ### Switching Capacity * **Voltage:** 125V / 250V AC (Standard) * **Current:** 5A to 10A (Depending on inductive vs. resistive load) * **Contact Type:** Usually **SPDT (Single Pole Double Throw)**, allowing for both Normally Open (NO) and Normally Closed (NC) configurations. ### Connectivity * **Insulation Resistance:** Usually 100MΩ minimum (at 500V DC). * **Contact Resistance:** 25mΩ maximum (initial value). * **Dielectric Strength:** 1,000V AC for 1 minute between non-consecutive terminals. --- ## 3. Operational Mechanics The "R" in the suffix usually denotes the **Actuator Type**. In the KMMLS series: 1. **Operating Force (OF):** The amount of force required to trigger the switch. 2. **Pre-Travel (PT):** The distance the actuator moves before the electronics "click." 3. **Over-Travel (OT):** The safety distance the actuator can move after switching without damaging the internal parts. --- ## 4. Typical Applications * **Safety Interlocks:** Ensuring a machine guard is closed before the circuit completes. * **End-of-Travel Sensing:** Stopping a motor when a carriage reaches the end of a rail. * **Object Counting:** Triggering a pulse every time a product passes on a conveyor. ---
