DESCRIPTION

The TSSP940.. series are the latest generation of compact

infrared detector modules for presence, fast 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. The sensitivity of the device is selectable

as shown on the electrical and optical characteristics table.

This component has not been qualified according to

automotive specifications.
