The **STD02Y-R** is a specific type of identification marker used in electrical and electronic systems, manufactured by **TE Connectivity (Raychem)**. It belongs to the **STD series** of snap-on pre-printed cable markers. --- ## 1. Technical Specifications The part number follows a specific nomenclature used for industrial marking. Below is the breakdown of its physical and technical attributes: | Feature | Specification | | :--- | :--- | | **Manufacturer** | TE Connectivity / Raychem | | **Marker Type** | Snap-On (Snap-on Pre-Printed Cable Markers) | | **Symbol/Character** | **R** (The "R" suffix indicates the letter printed) | | **Marker Color** | Yellow (Indicated by the "Y") | | **Material** | Polyoxymethylene (POM / Acetal) | | **Operating Temperature** | -40°C to +106°C | | **Expansion Range** | 1.40mm to 1.80mm (Typical for Size 02) | --- ## 2. Key Components and Design These parts are designed for efficiency in wiring looms and control panels. ### Material Properties * **Durability:** Made from high-grade Polyoxymethylene, which provides excellent resistance to chemicals, oils, and fuels. * **Grip Mechanism:** The "C" shape design allows the marker to be snapped onto a wire that has already been terminated (connected), meaning you do not need to disconnect the wire to apply it. ### The "Snap-on" System * **Expansion:** The marker is flexible enough to open and grip wires within a specific diameter range. * **Locking:** Once snapped on, the internal "legs" ensure the marker does not slide easily or rotate unintentionally. --- ## 3. Applications The STD02Y-R is used primarily in environments where clear cable identification is critical for safety and maintenance: 1. **Industrial Control Panels:** Labeling signal wires for PLC inputs and outputs. 2. **Telecommunications:** Organizing patch cables and complex wiring racks. 3. **Automotive/Aerospace:** Marking harnesses where temperature fluctuations and chemical exposure are common. 4. **Maintenance:** Retrofitting labels onto existing systems without disrupting the circuit. --- ## 4. Part Number Decoding To understand the specific variant, here is how the part number is structured: | Segment | Meaning | | :--- | :--- | | **STD** | Series Name (Snap-on Tech Designation) | | **02** | Size (Determines the wire diameter compatibility) | | **Y** | Color Code (Yellow background) | | **R** | Character Printed (The letter "R") | ---
