DESCRIPTION
The TSSP57P38 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.

FEATURES
• Height of 0.8 mm
• Up to 2 m for proximity sensing
• Receives 38 kHz modulated signal
• Photo detector and preamplifier in one package
• Low supply current
• Shielding against EMI
• Visible light is suppressed by IR filter
• Insensitive to supply voltage ripple and noise
• Supply voltage: 2.0 V to 5.5 V
• Material categorization: for definitions of compliance
