and Fast Proximity Applications

MECHANICAL DATA

Pinning:

APPLICATIONS

• Reflective sensors for hand dryers, towel or soap

dispensers, water faucets, toilet flush

• Vending machine fall detection

• Security and pet gates

• Person or object vicinity activation

• Fast proximity sensors for toys, robotics, drones, and

other consumer and industrial uses

FEATURES

• Up to 2 m for presence and proximity sensing

• Uses modulated bursts of infrared light

• 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

DESCRIPTION

The TSSP40.. series are compact infrared detector modules

for presence and fast proximity sensing applications. They

provide an active low output in response to infrared bursts

at 940 nm. The frequency of the burst should correspond to

the carrier frequency shown in the parts table.

This component has not been qualified according to

automotive specifications.
