The **W2CE-534-R2/UL** is a specialized industrial component, typically categorized as a **terminal block assembly** or a **power distribution module**, often associated with brands like **DDK (Dai-ichi Denshi Kogyo)** or similar manufacturers of industrial interconnects. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. General Specifications This part is designed for heavy-duty industrial environments where secure, vibration-resistant wiring is required. | Feature | Specification | | :--- | :--- | | **Series** | W2CE Series | | **Type** | Terminal Block / Interface Module | | **Mounting** | DIN Rail or Panel Mount | | **Compliance** | UL (Underwriters Laboratories) Recognized | | **Pitch** | Typically 5.0mm or 7.5mm (standard for industrial control) | --- ### 2. Key Electronic Characteristics The electronic integrity of the W2CE-534-R2/UL is defined by its ability to handle high current and maintain insulation under stress. * **Voltage Rating:** Usually rated for **300V to 600V AC/DC**, depending on the specific application safety standards. * **Current Rating:** Designed to handle currents in the range of **10A to 20A per pole**. * **Contact Resistance:** Engineered for low resistance (typically **< 20mΩ**) to prevent heat buildup at the connection points. * **Dielectric Strength:** Capable of withstanding a test voltage (often **2000V AC** for 1 minute) without breakdown. --- ### 3. Material and Construction The "R2" and "UL" designations indicate specific material standards and revisions. * **Housing:** Made of **Polyamide (PA66)** or **PBT (Polybutylene Terephthalate)**, which is UL94V-0 flame retardant. * **Contacts:** High-conductivity **Copper Alloy** with **Tin or Nickel plating** to prevent oxidation and ensure long-term conductivity. * **Screw Clamping:** Uses a "Cage Clamp" or "Pressure Plate" mechanism to ensure the wire is held securely without shearing the strands. --- ### 4. Part Number Breakdown (Typical) While internal manufacturer codes vary, the suffix usually denotes: | Segment | Meaning | | :--- | :--- | | **W2CE** | Series Identifier (Wire-to-Board or Wire-to-Wire interface) | | **534** | Configuration code (Specific to number of positions/poles or layout) | | **R2** | Revision 2 (indicates an engineering update or physical modification) | | **UL** | Certified for safety standards in North American markets | --- ### 5. Application Areas These parts are commonly found in: 1. **PLC (Programmable Logic Controller) I/O Modules:** Used to bridge external field wiring to internal control boards. 2. **Industrial Power Supplies:** For distribution of DC power across multiple rails. 3. **CNC Machinery:** Handling signal and power routing in high-vibration environments. ---
