Optical Sensors Are Road Ready

Offered in 5.5 mm x 5.85 mm x 7 mm SMD packages for automotive and industrial applications, Vishay Intertechnology’s AEC-Q101 qualified TCUT1630X01 and TCUT1800X01 are described as the industry's first 3- and 4-channel transmissive optical sensors, respectively.  The triple-channel TCUT1630X01 includes an infrared emitter and three phototransistor detectors located face to face in a surface-mount package. With a taller dome than previous-generation devices and an additional channel for a vertical push function or indexing tab, the device is ideal for turn and push encoding. The quad-channel TCUT1800X01 includes two infrared emitters and four phototransistor detectors, and it can detect up to 16 positions for absolute and incremental encoding.


Both sensors can detect motion, speed, and direction. They can be used as position sensors for encoders in high temperature automotive environments close to motors, in addition to turn interior knobs, ignition locks, adaptive headlights, and electric power steering (EPS) systems. In industrial applications, the devices are viable for monitoring gas or water meters and for detecting the status of doors, panels, and inserted coins or credit cards.

TE connector, relay and filter solutions can help create a fine maze network of power-cabling to the lights needed for vertical farming. Their solutions are interchangeable, easy-to-install, and will last for years in variable humidity environments.


The TCUT1630X01 and TCUT1800X01 deliver a typical output current of 1.3 mA and operate at a wavelength of 950 nm. The optical sensors feature a 3-mm gap width and apertures of 0.3 mm, and they offer a wide temperature range of -40 °C to +105 °C. With a Moisture Sensitivity Level rating of 1 (MSL1), the TCUT1630X01 and TCUT1800X01 have an unlimited floor life. Compatible with reflow solder processes according to JEDEC-STD-020D, the devices are RoHS-compliant, halogen-free, and Vishay Green.


Samples and production quantities of the optical sensors are available now, with lead times of eight to 10 weeks for large orders. Pricing for U.S. delivery in 5,000-piece quantities is $0.90 per piece for the TCUT1630X01 and $1.20 per piece for the TCUT1800X01. Datasheets are on tap for the TCUT1630X01 and TCUT1800X01.
