521 Series 5mm IR LEDs & Phototransistors

Dialight 521 Series 5mm IR LEDs and Phototransistors deliver reliable performance in compact and demanding applications, with effective use in matching phototransistors. These LEDs emit infrared light in the 940nm and 950nm wavelengths with high radiant intensity through water-clear lenses. The 521 series 5mm devices feature high-performance optical sensing, signaling, and non-contact detection. These 5mm IR LEDs and phototransistors operate within the -25°C to 100°C operating temperature range. The 521 series 5mm IR LEDs and phototransistors are RoHS-compliant and Pb-free. These single-color LEDs are ideal for high-reliability applications in industrial and consumer markets. The 521 series devices are suitable for remote controls, IR data transmission, industrial automation, safety sensors, medical instrumentation, lab diagnostics, security systems, and motion detectors.
