ams OSRAM SFH 4727AS A01 OSLON® Black 940nm High-Power Stealth IR LED

Introduction

The ams OSRAM OSLON® Black SFH 4727AS A01 is a high-performance infrared emitter specifically engineered for manufacturers requiring intense radiant power and a focused light distribution within a compact footprint. Operating at a centroid wavelength of 940 nm, this component is the gold standard for "stealth" applications where a visible red glow must be eliminated-a critical requirement for automotive driver monitoring systems (DMS) and high-security surveillance.

For LED module manufacturers and fixture designers, the A01 version represents an optimized variant of the OSLON Black platform. Its integrated silicone lens provides a 50-degree viewing angle, concentrating the radiant energy into a tight beam. This architecture facilitates longer throw distances and significantly higher radiant intensity (mW/sr) compared to standard 120° emitters, allowing fixture manufacturers to improve image quality for biometric sensors while maintaining a lean Bill of Materials (BOM).

Key Product Features

• 940nm "Invisible" Performance: Optimized for covert detection. Unlike 850nm emitters, 940nm light is virtually undetectable to the human eye, meeting the non-negotiable requirements of automotive cabin sensing and government-level security.
• Precision 50° Optical Control: The integrated lens concentrates infrared power to achieve maximum "light-on-target." This facilitates high-contrast imaging for facial recognition and iris scanning at a distance without requiring bulky secondary optics.
• Automotive-Grade Reliability (AEC-Q102): Built on a robust ceramic platform, the SFH 4727AS A01 is designed to withstand extreme thermal cycling and high-vibration environments, preserving the L70 lifespan in 24/7 mission-critical hardware.
• Superior Thermal Path Efficiency: Featuring a junction-to-solder point thermal resistance of typically 5.3 K/W, this component ensures efficient heat transfer. This stability protects the InGaAlP chip during continuous high-current operation (up to 1.5A DC).
• High Pulsed Current Capability: Engineered for synchronized shutter applications, handling pulses up to 5A, which allows for massive radiant intensity in high-speed machine vision systems.

The SFH 4727AS A01 is a staple light source for:

• Automotive DMS & Cabin Sensing: Stealth illumination for eye-tracking and fatigue detection sensors requiring AEC-Q102 certification.
• Covert CCTV Surveillance: High-intensity focused illumination for security cameras where high contrast is needed without a visible light footprint.
• Biometric Identification: Reliable 940nm source for facial recognition and iris scanning in mobile and secure facility hardware.
• Gesture Recognition & Robotics: Compact light engines for human-machine interface (HMI) sensors and industrial robotic spatial mapping.
• Industrial Machine Vision: Saturated IR emitters for high-speed automated inspection lines requiring narrow-beam throw.
