DESCRIPTION
TSSP950..TT - top view taped, 2200 pcs/reel
TSSP950..TR - side view taped, 2300 pcs/reel
The TSSP950.. series are compact infrared detector
modules 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.
APPLICATIONS
• Reflective sensors for hand dryers, towel or soap
dispensers, water faucets, toilet flush
This component has not been qualified according to
automotive specifications.
• 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
