Three- and four-channel optical sensors are AEC-Q101-qualified

Transmissive sensors are offered in compact 5.5 x 5.85 x 7.0mm surface mount packaging by Vishay Intertechnology. The TCUT1630X01 and TCUT1800X01 are designed for automotive and industrial applications.

The AEC-Q101-qualified transmissive optical sensors are believed to be the industry’s first three-channel (TCUT1630X01) and four-channel (TCUT1800X01) transmissive sensors.

The TCUT1630X01 includes an infra red emitter and three photo transistor 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 suitable for turn and push encoding. The TCUT1800X01 includes two infra red emitters and four photo transistor 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 TCUT1630X01 and TCUT1800X01 can be used for monitoring gas or water meters and for detecting the status of doors, panels, and inserted coins or credit cards.

The TCUT1630X01 and TCUT1800X01 deliver a typical output current of 1.3mA and operate at a wavelength of 950nm. The optical sensors feature a 3.0mm gap width and apertures of 0.3mm, and they offer a wide temperature range of -40 to +105 degree C. Moisture Sensitivity Level (MSL) rating is MSL1 for the TCUT1630X01 and TCUT1800X01 and both have an unlimited floor life. Compatible with reflow solder processes according to JEDEC-STD-020D, the devices are RoHS-compliant and halogen-free.

Samples and production quantities of the optical sensors are available now, with lead times of eight to 10 weeks for large orders.

Vishay Intertechnology manufactures discrete semiconductors (diodes, MOSFETs, and infra red optoelectronics) and passive electronic components (resistors, inductors, and capacitors) which are used in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
