HONG YE SILICONE Electronic Potting for Hall Effect Sensors is a specialized Thermally Conductive Potting Compound, also known as Silicone Potting Compound and Electronic Encapsulation Adhesive, tailored for Hall effect sensor encapsulation. Made of high-purity Silicone raw materials, it is a two-component addition-curing silicone with low viscosity, flame retardancy (UL94-V0), and excellent thermal conductivity (≥0.8 W/(m·K)). It cures at room or heated temperature, offers IP65 waterproof grade, strong adhesion, and stable performance from -60℃ to 220℃, complying with EU RoHS, and supporting full parameter customization (around 198 characters).
Product Overview
Our Electronic Potting for Hall Effect Sensors is a professional Silicone Encapsulant developed for the encapsulation, insulation and protection of Hall effect sensors. As a leading manufacturer of Electronic Potting Compound and silicone raw materials, we optimize the formula for the high precision, anti-interference and thermal conductivity requirements of Hall effect sensors. Unlike ordinary potting compounds, it features low viscosity, good fluidity for precise filling of small sensor structures, excellent electromagnetic shielding, and high thermal conductivity to dissipate heat efficiently, ensuring sensor accuracy and extending service life for procurement partners.
Key Features & Advantages
- High Precision & Anti-Interference: Low viscosity and excellent fluidity, enabling full filling of tiny gaps in Hall effect sensors; superior electromagnetic shielding and insulation (dielectric strength ≥25 kV/mm), avoiding external interference and ensuring accurate magnetic field detection, which is critical for sensor performance.
- Excellent Thermal Conductivity & Temperature Adaptability: Thermal conductivity ≥0.8 W/(m·K), quickly dissipating heat generated by sensor operation; operating temperature ranges from -60℃ to 220℃, with outstanding heat, moisture and cold resistance, adapting to harsh working environments and extending sensor service life.
- Flame Retardant & Waterproof: Flame retardancy reaches UL94-V0 grade, meeting international safety standards; IP65 waterproof and dustproof grade, effectively isolating moisture and dust, preventing sensor short circuits and performance degradation, suitable for outdoor and harsh environment applications.
- Strong Adhesion & Easy Operation: Two-component (1:1 weight ratio) design, easy to mix evenly; strong adhesion to PC, PP, ABS, PVC and metal surfaces (common in Hall sensors); cures at room temperature (4-5 hours) or heated (80℃ for 20 minutes), optional vacuum degassing, improving production efficiency.
- Environmental Protection & High Stability: Fully compliant with EU RoHS directive, non-toxic and harmless; low volatility, no stratification after long-term storage; cures into soft rubber, with good impact resistance, protecting sensors from mechanical damage.
How to Use (Step-by-Step Guide)
- Pre-Mixing Preparation: Fully stir Component A and Component B separately in their respective containers to ensure uniform consistency, avoiding sedimentation affecting curing effect and sensor protection.
- Mixing: Mix Component A and Component B at a 1:1 weight ratio, stir slowly and evenly to avoid generating air bubbles, which may affect insulation and thermal conductivity of Hall effect sensors.
- Degassing (Optional): Put the mixed Potting Compound into a vacuum container, degas at 0.08MPa for 5 minutes to completely eliminate air bubbles, then pour it into Hall effect sensor molds or casings.
- Curing: Cure at room temperature for 4-5 hours (full curing) or heat at 80℃ for 20 minutes to accelerate curing; for thick applications, extend curing time appropriately. Note: Temperature affects curing speed, heat curing is recommended in winter.
