The TSSP77P38 is a compact infrared detector module for proximity sensing application. 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.

• Up to 2 m for proximity sensing
• Very low supply current
• Photo detector and preamplifier in one package
• Shielding against EMI
• Supply voltage: 2.5 V to 5.5 V
• Visible light is suppressed by IR filter
• Capable of side or top view
• Insensitive to supply voltage ripple and noise
• Two lenses for high sensitivity and wide
   receiving angle
• 940 nm peak wavelength
• Material categorization: for definitions of compliance
   please see

• 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
