DESCRIPTION
The TSSP40..SS1XB are compact infrared detector modules for presence sensing applications. They provide an active low output in response to infrared bursts at 940 nm. The TSSP40..SS1XB are 20 x less sensitive than the TSSP40.., for ease of use in reflective applications at less than 1 m range where high sensitivity is not needed and can complicate the design.
This component has not been qualified to automotive specifications.
FEATURES
• Constant gain for consistent results under any
lighting condition
• Up to 1 m for presence sensing
• 940 nm peak wavelength
• PIN diode and sensor IC 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: 2.5 V to 5.5 V
• Material categorization: for definitions of compliance
