The **CS-16-R** typically refers to a high-quality **Rotary Selector Switch** commonly used in industrial controls, audio equipment, and telecommunications. Specifically, this model is often associated with manufacturers like *Nidec Components (formerly Copal Electronics)*. Below is a breakdown of its technical specifications and electronic characteristics. ### 1. General Specifications The CS-16 series is designed as a miniature, surface-mount or through-hole rotary switch used to configure circuits or set digital addresses. | Feature | Description | | :--- | :--- | | **Part Number** | CS-16-R | | **Type** | Rotary Selector Switch | | **Positions** | 16 Positions (Hexadecimal) | | **Actuator Type** | Recessed (Flush) - indicated by the "R" | | **Contact Material** | Gold-plated (to prevent oxidation) | | **Mounting Type** | Through-hole or Surface Mount (depending on suffix) | --- ### 2. Key Electronic Characteristics The "R" suffix specifically denotes the **Recessed Actuator**, meaning the switch requires a screwdriver to turn, preventing accidental changes to the settings. * **Logic Output:** It provides a Binary Coded Hexadecimal (BCH) output. As you rotate the switch from 0 to F (16 positions), the pins bridge to create specific binary patterns. * **Switching Capacity:** * **Voltage:** Max 50V DC (non-switching) / 5V DC (switching). * **Current:** Max 100mA (non-switching) / 100mA (switching). * **Insulation Resistance:** Usually 1,000MΩ minimum at 100V DC. * **Dielectric Strength:** 250V AC for 1 minute. --- ### 3. Pin Configuration and Internal Logic The switch typically features 5-6 pins. One is the "Common" (C) pin, and the others represent the binary weights (1, 2, 4, 8). #### Hexadecimal Truth Table (Partial Example) | Position | Binary Weight (8) | Binary Weight (4) | Binary Weight (2) | Binary Weight (1) | | :--- | :---: | :---: | :---: | :---: | | 0 | OFF | OFF | OFF | OFF | | 1 | OFF | OFF | OFF | **ON** | | 2 | OFF | OFF | **ON** | OFF | | ... | ... | ... | ... | ... | | F (15) | **ON** | **ON** | **ON** | **ON** | --- ### 4. Common Applications * **Address Setting:** Used on PCB boards to set a unique ID for a device on a bus (like RS-485 or CAN bus). * **Mode Selection:** Selecting between 16 different pre-programmed operating modes in embedded systems. * **Industrial Controls:** Setting timer values or configuration parameters in PLCs. --- ### 5. Mechanical and Environmental * **Operating Torque:** 10 mN·m to 20 mN·m. * **Durability:** Typically rated for 10,000 steps/rotations. * **Sealing:** Most models in this series are **Washable**, meaning they are sealed (O-ring) to withstand wave soldering and cleaning processes. ---
