Electric heater ClearView™

with temperature probecompact

Overview
The ClearView™ ultra-thin flexible heater platform from KLC is a polyimide (PI) PTC heater engineered to prevent lens fogging, enable rapid de-icing/defrost and maintain optical clarity for ADAS cameras, LiDAR and advanced vision systems. Offered as a 0.22 mm ±0.05 mm flexible heater with optional integrated thermal sensors and EMI/RFI shielding, it is designed for zero-interference optical performance and uniform thermal distribution in harsh environments.

Key Features

• Ultra-thin profile: 0.22 mm (excluding adhesive) for integration without optical distortion.
• Wide operating temperature range and verified thermal shock survivability.
• Automotive-grade manufacturing readiness (IATF 16949) and high durability (>1,000,000 ON/OFF cycles).
• Optional integrated NTC/thermistor for closed-loop temperature control.
• Zero-interference EMI/RFI shielding to protect adjacent radar and LiDAR systems.
• Fast response: optimized power-density distribution to reach working temperature in ~15 seconds.
• Customizable operating voltage: 1.5 V–600 V AC/DC (custom voltages available).

Applications

• ADAS camera lenses and automotive autopilot optical systems
• LiDAR sensor anti-icing and de-icing
• UAV/drone navigation and high-altitude imaging cameras
• Outdoor CCTV and surveillance optics for continuous visibility in extreme weather
• Localized heating for precision optics and embedded sensors

Power Density vs. Temperature Rise (ΔT)
Power Density: up to 1.5 W/cm² (customizable fast-heating). Typical target ΔT values (W/cm² required):

• +20°C — Ø13 mm: 0.1422 — Ø25 mm: 0.0927 — Ø50 mm: 0.0806
• +60°C — Ø13 mm: 0.4623 — Ø25 mm: 0.2908 — Ø50 mm: 0.2500
• +80°C — Ø13 mm: 0.6380 — Ø25 mm: 0.4046 — Ø50 mm: 0.3482

Installation and Handling Notes

• Recommended bonding: 3M 467MP PSA with bubble-free, full-contact bonding to avoid localized overheating and optical path distortion.
• For high-power / low-resistance heaters (<10 Ω) never energize unloaded; ensure tight contact to a heat sink or use mechanical clamping.
• Anti-vibration mounting: sandwich mounting between metal plates; do not self-drill — request pre-engineered mounting holes to avoid cutting heating traces.
• For sustained high-temperature (>160°C) or vacuum/space use: use FEP lamination or mechanical clamping; standard PSA not rated for continuous extreme-temp or cryogenic conditions.

FAQ Highlights

• Recommended lens offset: maintain lens ~10°C–15°C above ambient for automotive cameras to prevent fogging.
• To increase warm-up speed: raise power density within safe limits (max 1.5 W/cm²), reduce heat loss with insulation or higher-conductivity mounts, or adjust supply voltage (power ∝ V²) while observing electrical safety.
• Flexible heaters vs. enclosure fan heaters: flexible heaters are preferred for localized, space-constrained precision heating; fan heaters are better for warming entire enclosures.
