Vishay Intertechnology Introduces New Transmissive Sensors: Enhancing Flexibility and Performance
MALVERN, Pa., Jan. 07, 2026 (GLOBE NEWSWIRE) — Vishay Intertechnology, Inc. (NYSE: VSH) has announced the expansion of its innovative transmissive sensor family with the launch of two new surface-mount devices. The newly introduced sensors, intended for industrial, consumer, and telecom applications, are designed to accommodate a wide range of mechanical designs.
Overview of New Sensor Devices
The latest offerings from Vishay, the VT171P single-channel and the VT172U dual-channel sensors, come in a compact package measuring 5.5 mm by 4 mm by 5.7 mm. A notable feature of these models is their 42% increase in dome height compared to previous-generation devices. This enhanced dome height provides increased vertical headroom, allowing for more design flexibility in applications that often utilize large code wheels, such as turn-and-push mechanisms.
- Applications: Suitable for use as position sensors in:
- Industrial automation systems
- Consumer entertainment products
- Home appliances
- Health and care devices
- Switches, relays, and antennas
- Mobile broadband routers
- Detection Capabilities: Both sensors can detect motion and speed, with the VT172U capable of determining direction due to its dual-channel configuration.
Technical Specifications and Features
The VT171P includes an infrared emitter paired with a phototransistor detector in a surface-mount configuration. Meanwhile, the VT172U consists of an infrared emitter coupled with two phototransistor detectors, offering enhanced functionality. Both models provide:
- Typical Output Current: 1.5 mA
- Operating Wavelength: 950 nm
- Gap Width: 3 mm
- Aperture Size: 0.3 mm
- Fast Response Times: Rise time of 14 μs and fall time of 21 μs
Both sensors carry a Moisture Sensitivity Level rating of 1 (MSL1), indicating an unlimited floor life. They are also compatible with lead (Pb)-free reflow solder processes, complying with JEDEC-STD-020, and conform to halogen-free and RoHS standards, aligning with the Vishay Green initiative.
Availability and Future Implications
Samples and the full production quantities of these new transmissive sensors are currently available, with anticipated lead times of 10 weeks. As part of its commitment to innovation, Vishay continues to produce one of the largest portfolios of discrete semiconductors and passive electronic components in the world, serving diverse markets including automotive, industrial, computing, telecommunications, military, aerospace, and medical.
Vishay Intertechnology, Inc. remains a formidable player in the semiconductor industry, as evidenced by its listing on the NYSE under the symbol VSH. This new product launch underscores the company’s dedication to providing cutting-edge technology that meets the evolving needs of its customers.
