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 switch

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

other consumer and industrial uses

FEATURES

• Up to 2 m for presence and proximity sensing

• Up to 20 m distance for light curtain application

• Uses continuous AC signal or burst pattern of

infrared light

• Small sensitivity scattering range

• 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: 2.0 V to 3.6 V

• Material categorization: for definitions of compliance

DESCRIPTION

The TSSP930.. device is the latest generation of compact

infrared detector module for presence, proximity, or light

curtain 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.
