Vishay Semiconductors TCPT1600X01 and TCUT1600X01 optical sensors

Vishay Intertechnology has introduced two AEC-Q101-qualified surface-mount transmissive optical sensors for automotive and industrial applications.

Offered in a 5.5 x 4 x 5.7 mm package, the Vishay Semiconductors single-channel TCPT1600X01 and dual-channel TCUT1600X01 feature an increased dome height compared with previous devices. Due to their tall dome design, the devices offer vertical headroom for the code wheel in turn-and-push applications.

The devices can be used as position sensors for encoders in high-temperature environments close to motors, in addition to turn knobs, ignition locks and adaptive headlights. Both sensors can detect motion and speed. With dual channels, the TCUT1600X01 can also be used to detect direction in applications such as electronic power steering (ESP) systems.

The single-channel TCPT1600X01 includes an infrared emitter and phototransistor detector located face to face in a surface-mount package, while the dual-channel TCUT1600X01 includes an infrared emitter and two phototransistor detectors. Both sensors deliver a typical output current of 1.6 mA and operate at a wavelength of 950 nm. They feature a 3 mm gap width and apertures of 0.3 mm, and they operate over a wide temperature range of -40 to +105°C.

With a moisture sensitivity level rating of 1, the sensors have an unlimited floor life. Compatible with reflow solder processes according to JEDEC-STD-020D, the devices are halogen-free, RoHS compliant and Vishay Green.
