Vishay TSSP95056TR, 56kHz IR Receiver, 950nm ± 50 °, 8m Range, 2 V - 3.6V, SMT, 6.8 x 3 x 3.2mm

The Vishay IR sensor module for reflective sensor with 56 kHz carrier frequency is 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. It uses continuous AC signal or burst pattern of infrared light. Visible light is suppressed by IR filter.It provides shielding against EMI It has up to 2 m for presence and proximity sensing
