Proximity Sensor Optical Photodiode 5mm 4-Pin SMD T/R
The HSDL-9100 is an analog-output reflective sensor with an integrated high efficiency infrared emitter and photodiode housed in a small form factor SMD package. The optical proximity sensor is housed in a specially designed metal-shield to ensure excellent optical isolation resulting in low optical cross-talk. HSDL-9100 has an option for 2.7 or 2.4mm height parts with its small form SMD package and at a detection range from near zero to 60mm. It is specifically optimized for size, performance and ease of design in mobile constrained applications such as mobile phones and notebooks. HSDL-9100 has extremely low dark current and high signal to noise ratio (SNR) where high SNR is achieved with a pair of highly efficient infrared emitter and highly sensitive detector.
