Frequently Asked Questions
What detection range and output power does the 950 nm SIM-20ST infrared LED provide for security cameras?
The SIM-20ST's 7 mW output at 950 nm delivers reliable illumination for infrared camera sensors up to 10 meters in darkness, sufficient for 1-megapixel night vision at 50 mA forward current. The 950 nm wavelength also minimizes visible glow perception, making it ideal for covert surveillance applications where IR illumination must remain undetectable to the human eye.
What forward current and maximum dissipation rating limits apply to the SIM-20ST?
The 50 mA maximum forward current generates approximately 2V forward voltage drop, dissipating 100 mW at rated operation. The high-reliability construction supports continuous 50 mA operation across 0°C to 60°C ambient temperature, with derating to 30 mA above 60°C to maintain long-term reliability in industrial environments.
How does the 950 nm infrared wavelength compare to alternative IR LED options for sensor design?
The 950 nm wavelength matches standard silicon photodiode peak sensitivity, enabling direct coupling to CMOS image sensors and discrete IR detectors without optical filters. Compared to 880 nm alternatives (better visible transparency but lower photodiode sensitivity), or 1050 nm (lower absorption by dust), 950 nm offers best-in-class optical coupling efficiency for consumer IR remote and security applications.
When would you select SIM-20ST over a red LED for outdoor proximity sensor applications?
The SIM-20ST's 950 nm infrared emission penetrates ambient light and weather conditions far better than visible red LEDs, enabling reliable daytime motion detection at 5-10 meter ranges. While red LEDs consume less power and offer lower cost, the infrared variant eliminates false triggers from sunlight and artificial lighting variations common in outdoor security perimeter monitoring.
