The **D4G0106S-R30F** is a specific model of a **Rotary Switch** manufactured by Nidec Components (formerly Copal Electronics). It is designed for high-reliability switching in compact electronic devices. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and mechanical characteristics of the D4G0106S-R30F: | Feature | Specification | | :--- | :--- | | **Component Type** | Rotary Switch | | **Number of Poles** | 1 Pole | | **Number of Positions** | 6 Positions | | **Contact Timing** | Shorting (Make-before-break) | | **Switching Angle** | 30° per position | | **Contact Material** | Gold plated | | **Mounting Type** | Through-hole (PCB Mount) | | **Rotational Life** | ~10,000 cycles | --- ### 2. Deep Dive into Electronic Features #### A. Contact Configuration (1-Pole, 6-Position) This switch allows a single input signal (the pole) to be routed to one of six different output paths. The "R30" in the part number signifies a **30-degree** throw angle between each of the six positions. #### B. Shorting Contact (Make-before-break) The "S" in the suffix usually denotes a **Shorting** mechanism. - **Definition:** As you turn the dial, the switch momentarily connects the next position before disconnecting the current one. - **Purpose:** This prevents "floating" inputs or electrical spikes (arcing) during the transition, which is critical in audio or sensitive signal processing applications. #### C. Gold-Plated Contacts The internal contacts are gold-plated to ensure low contact resistance and to prevent oxidation over time. This makes the component suitable for low-voltage/low-current logic signals where signal integrity is paramount. #### D. Environmental Durability These switches are typically sealed to withstand soldering processes (wave soldering) and to prevent the ingress of dust or flux, ensuring the internal mechanisms remain clean for their 10,000-cycle lifespan. --- ### 3. Common Applications * **Test & Measurement:** Selecting different measurement ranges (e.g., Voltage vs. Ohms). * **Industrial Controls:** Mode selection for machinery or PLC inputs. * **Audio Equipment:** Selecting input sources or gain levels. * **Communication Devices:** Channel switching in radio or networking hardware. ---
