The **TMS-RJS-RIBBON-4HT** is a high-performance thermal transfer ribbon specifically engineered for industrial identification and labeling applications. It is part of TE Connectivity’s Raychem product line, designed to be used with heat-shrinkable sleeves and cable markers. --- ### 1. Technical Specifications The "4HT" designation indicates a **High-Temperature** resin formulation, ensuring that the print remains legible even after exposure to extreme environments. | Feature | Specification | |:---|:---| | **Ribbon Type** | Thermal Transfer Resin | | **Color** | Black | | **Ink Side** | Ink Out (standard for RJS printers) | | **Width** | 100 mm (approx. 4 inches) | | **Length** | 300 meters | | **Core Diameter** | 25.4 mm (1 inch) | | **Primary Compatibility** | T312M, T312Mi, and T6112DS Printers | --- ### 2. Electronic Industry Applications This ribbon is critical in the electronics and aerospace sectors due to its chemical and physical resistance properties: * **Heat-Shrink Identification:** Used to print on TMS-SCE, HT-SCE, and ZH-SCE heat-shrink sleeves. * **Circuit Board Labeling:** Can be used on high-durability polyester labels for PCB tracking. * **Cable Harnessing:** Ideal for labeling wiring in avionics, military electronics, and industrial control panels. --- ### 3. Key Performance Properties Because this is a **High-Temperature (HT)** ribbon, it meets several stringent industrial standards: 1. **Fluid Resistance:** Resistant to common electronic cleaning solvents, hydraulic fluids, and fuels. 2. **Abrasion Resistance:** The resin-based ink binds deeply into the substrate, preventing the text from rubbing off during manual handling of wire harnesses. 3. **Thermal Stability:** Maintains legibility even if the substrate is subjected to high-temperature baking cycles or engine compartment heat. 4. **MIL-SPEC Compliance:** When used with compatible TE sleeves, it often meets **MIL-STD-202 Method 215** for print permanence. --- ### 4. Usage Requirements To achieve the rated performance, the following electronic settings are typically adjusted in the printer driver: * **Darkness/Burn Setting:** Usually requires a high heat setting (25–30 range on most industrial printers) due to the high resin content. * **Print Speed:** Recommended at lower speeds (approx. 50mm/s) to ensure proper ink transfer. ---
