16672 Shielding against EMI Visible light is suppressed by IR filter Insensitive to supply voltage ripple and noise Supply voltage: 2.5 V to 5.5 V Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 MECHANICAL DATA
Pinning 1 = OUT, 2 = GND, 3 = VS DESCRIPTION
The TSSP4P38 is a compact infrared detector module for proximity sensing applications. It receives 38 kHz modulated signals and has a peak sensitivity of 940 nm. The length of the detector's output pulse varies in proportion to the amount of light reflected from the object being detected. APPLICATIONS Object approach detection for activation of displays and user consoles, signaling of alarms, etc. Simple gesture controls Differentiation of car arrival, static, car departure in parking lots Reflective sensors for toilet flush Navigational sensor for robotics PARTS TABLE
