The **D316-R** is typically identified as a specialized **rotary dip switch** or a specific **electromechanical relay component** depending on the manufacturer (most commonly associated with high-precision switching electronics). Below is a breakdown of the electronic specifications and characteristics generally associated with this part number. --- ### 1. General Specifications The D316-R is designed for PCB (Printed Circuit Board) mounting, often used for configuration settings in industrial electronics. | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary Coded Switch / DIP Switch | | **Positions** | 16 Positions (Hexadecimal) | | **Output Code** | Real Code (Binary Coded Hexadecimal) | | **Actuator Type** | Flat / Recessed (requires screwdriver) | | **Mounting Type** | Through-hole (THT) or SMD (depending on suffix) | | **Pitch** | 2.54mm (Standard) | --- ### 2. Electronic Characteristics These parts are engineered for low-power signal switching rather than high-power load management. * **Voltage Rating:** Typically rated for **24V DC** to **50V DC**. * **Current Rating (Switching):** Usually **100mA**. * **Current Rating (Non-Switching):** Up to **400mA** (carry current). * **Contact Resistance:** < 100mΩ (initial). * **Insulation Resistance:** > 1,000MΩ at 100V DC. * **Dielectric Strength:** 250V AC for 1 minute. --- ### 3. Pin Configuration & Logic The "16-position" nature means the switch cycles from **0 to F** (0, 1, 2... 9, A, B, C, D, E, F). | Position | Binary Output (C, 1, 2, 4, 8) | | :--- | :--- | | **0** | All circuits open | | **1** | Pin 1 connected to Common | | **8** | Pin 8 connected to Common | | **F** | All pins (1, 2, 4, 8) connected to Common | --- ### 4. Materials and Durability The "R" suffix often denotes **RoHS Compliance** or **Tape & Reel** packaging, depending on the specific manufacturer (like Apem, Omron, or Nidec). * **Contacts:** Gold-plated over nickel (for corrosion resistance and reliable low-voltage switching). * **Housing:** High-temperature thermoplastic (UL94V-0 rated). * **Operating Temperature:** Generally **-25°C to +70°C**. * **Mechanical Life:** Rated for approximately 10,000 to 20,000 steps. --- ### 5. Common Applications * **Address Setting:** Setting unique IDs for devices on a BUS (like RS-485 or CAN bus). * **Mode Selection:** Choosing operational modes on industrial motherboards. * **Configuration:** Adjusting frequency or timing parameters in telecommunications gear.
