Vishay Intertechnology Transmissive Sensors Offer Greater Vertical Headroom and Design Flexibility for Industrial and Consumer Applications

Vishay Intertechnology, Inc. has unveiled new transmissive sensors, the VT171P and VT172U, designed for a range of industrial, consumer, and telecom applications. These compact sensors, measuring 5.5 mm by 4 mm by 5.7 mm, incorporate a significant 42% increase in dome height compared to previous models. This enhancement grants greater mechanical design flexibility and additional vertical headroom for larger code wheels in applications requiring turn-and-push functionality, such as encoders in automation systems.

The single-channel VT171P features an infrared emitter paired with a phototransistor detector, while the dual-channel VT172U includes one infrared emitter along with two phototransistor detectors, facilitating motion and speed detection. Notably, the VT172U can also determine direction. Both models operate at a wavelength of 950 nm, deliver a typical output current of 1.5 mA, and exhibit rapid rise and fall times of 14 µs and 21 µs, respectively. They are designed with a 3 mm gap and 0.3 mm apertures to optimize performance.

Additionally, these sensors boast a Moisture Sensitivity Level rating of 1 (MSL1), granting them an unlimited floor life and making them compatible with lead-free reflow solder processes in accordance with JEDEC-STD-020. Both models are halogen-free and RoHS-compliant, aligning with green technology standards.

Vishay recently affirmed that samples and production quantities of these new sensors are currently available, with a 10-week lead time. As a key player in the semiconductor market, Vishay continues to support innovative designs across various industries, emphasizing its commitment to quality and customer satisfaction.
