LED Infrared LED L6895-10 High-power LED with miniature package L6895-10 is a high-power LED molded into a miniature, clear plastic package that emits infrared light at a peak emission wavelength of 940 nm. An optical encoder resistant to tough environmental conditions can be configured by combining L6895-10 with S7610-10 (made by Hamamatsu). Features Applications l Pd plated leads l Miniature package with lens l Peak emission wavelength: 940 nm l Rotary encoders, etc. ■ Absolute maximum ratings (Ta=25 °C) Parameter Forward current Reverse voltage Symbol IF VR Max.
