The **TCS-04-R** typically refers to a **4-Position Terminal Block Connector** or a specific series of **Dip Switches/Control Switches** depending on the manufacturer (most commonly associated with connectivity components or industrial control interfaces). Below is a breakdown of the electronic specifications and characteristics typically associated with this part number. --- ### 1. General Specifications The TCS series is generally designed for PCB mounting and signal routing. Here are the common electrical parameters: | Feature | Specification (Standard) | | :--- | :--- | | **Number of Positions** | 4 Positions | | **Current Rating** | 1A to 5A (depending on housing) | | **Voltage Rating** | 125V - 250V AC/DC | | **Contact Resistance** | < 20 mΩ | | **Insulation Resistance** | > 1000 MΩ | | **Operating Temperature** | -25°C to +85°C | ### 2. Physical Construction The "R" suffix often denotes a specific orientation (Right-Angle) or a specialized Material/RoHS compliance. * **Housing Material:** High-temperature thermoplastic (UL94V-0 rated). * **Contacts:** Phosphor bronze or Brass, usually plated with Tin or Gold to prevent oxidation. * **Pitch:** Common pitches include 2.54mm (0.1") or 3.81mm, depending on the specific manufacturer's footprint. * **Mounting Type:** Through-hole (THT) is the standard for the TCS-04 series. ### 3. Pinout and Configuration The "04" signifies a 4-pin layout. In electronic circuits, these are used for: 1. **VCC** (Power Supply) 2. **GND** (Ground) 3. **Signal A / TX** (Data transmission) 4. **Signal B / RX** (Data reception) --- ### 4. Implementation Example If you are integrating this into a PCB design using EDA software (like KiCad or Altium), you would treat it as a standard header or terminal interface. ```cpp // Logic representation for a 4-pin interface (TCS-04-R) #define PIN_POWER 1 #define PIN_GND 2 #define PIN_DATA1 3 #define PIN_DATA2 4 void setup() { pinMode(PIN_DATA1, INPUT); pinMode(PIN_DATA2, OUTPUT); } ``` ### 5. Common Applications * **Industrial Automation:** Connecting sensors to PLC inputs. * **Consumer Electronics:** Internal power routing between boards. * **Prototyping:** Used as a pluggable interface for modular hardware. ---
