The **STD06W-R** is a specific part number within a series of cable identification systems, primarily manufactured by **TE Connectivity (Raychem)**. It belongs to the **STD (Snap-On)** series of pre-printed cable markers. ### 1. Overview and Function The STD06W-R is an identification marker used to label wires and cables permanently. Unlike heat-shrink tubing, these are "snap-on" markers, meaning they can be applied even after the wires have been terminated or connected. | Feature | Specification | | :--- | :--- | | **Manufacturer** | TE Connectivity / Raychem | | **Series** | STD (Snap-On) | | **Marker Legend** | **R** (The letter 'R') | | **Background Color** | White | | **Legend Color** | Black | | **Installation Type** | Snap-on (Side entry) | --- ### 2. Technical Specifications The "06" in the part number indicates the size category, which determines the compatible cable diameter range. | Parameter | Details | | :--- | :--- | | **Cable Diameter Range** | 2.60mm to 3.50mm (0.102" to 0.138") | | **Material** | Polyoxymethylene (POM / Acetal) | | **Operating Temperature** | -40°C to +106°C (-40°F to +222°F) | | **Application Tool** | Included applicator (wand) or manual snap-on | | **Flammability** | UL94 HB rated | --- ### 3. Key Physical Characteristics * **Grip Mechanism:** The markers are designed with a "chevron" cut (V-shape) on the ends. This ensures that when multiple markers are placed together (e.g., to spell "RESET"), they lock into each other to prevent rotation and maintain alignment. * **Material Properties:** Made from high-quality Polyoxymethylene, these markers offer excellent chemical resistance to fuels, lubricants, and cleaning solvents. * **Expandability:** The material is resilient enough to snap over the insulation of a wire and then grip tightly without sliding. --- ### 4. Part Number Breakdown The part number **STD06W-R** is encoded as follows: 1. **STD**: Series name (Snap-on, Type STD). 2. **06**: Size code (2.6mm - 3.5mm cable OD). 3. **W**: Background color (W = White; Y = Yellow is also common). 4. **R**: The specific character printed on the marker. --- ### 5. Common Applications * **Control Panels:** Identifying signal wires in industrial PLC cabinets. * **Telecommunications:** Labeling patch cables and jumpers. * **Maintenance:** Retrofitting labels onto existing wiring without disconnecting terminals.
