Vishay Intertechnology Unveils New 40 LHE Linear Position Sensor for High-Accuracy Applications
March 25, 2026 – Vishay Intertechnology, Inc. (NYSE: VSH) has announced the launch of its latest innovation, the 40 LHE linear position sensor, designed specifically for high-accuracy displacement measurement in harsh environments. This compact device promises to deliver exceptional performance with an extended operational range and improved features that cater to a variety of demanding applications.
1. Enhanced Performance Metrics
The Vishay 40 LHE linear position sensor utilizes non-contacting Hall Effect technology, boasting a linearity specification of ± 1% over its full stroke of 40 mm. This marks a significant advancement from previous-generation devices, which were limited to electrical strokes of just 10 mm. The sensor achieves a remarkable resolution of 12 µm and is engineered for longevity, with a lifespan exceeding 10 million cycles.
This enhanced capability makes the 40 LHE particularly well-suited for applications requiring precise small displacement monitoring, such as:
- Infrastructure integrity monitoring (e.g., crackmeters in bridges and buildings)
- Digital farming applications (e.g., dendrometers)
- In-line process measurement
- Robotic grippers in industrial automation systems
- Medical robotic grasping forceps
In addition, the sensor is expected to play a vital role in throttle and pedal position sensors for e-bikes and motorcycles, as well as in railway equipment, ships, and agricultural machinery.
2. Rugged Design for Harsh Environments
Designed with durability in mind, the 40 LHE sensor features an IP67 sealing rating, ensuring reliable operation in challenging conditions. It can withstand high-frequency vibrations of up to 20 g and shocks of up to 50 g, making it ideal for demanding industrial and automotive environments.
To further enhance its reliability, the device incorporates reverse voltage and overvoltage input protections (-10 VDC and +20 VDC, respectively), effectively reducing the need for external protection circuitry and associated costs.
3. Seamless Integration and Usability
The 40 LHE is designed for easy integration into various automation systems, offering both analog ratiometric and digital (PWM) output signals. The sensor includes flexible mounting options with versatile “2 faces” fixing holes for either horizontal or vertical installation.
One of the standout features of the 40 LHE is its "true power on" capability. The device reports its position immediately upon power-up without the need for recalibration, re-homing, or initialization routines—even after a power loss. This eliminates the requirement for a battery backup and further reduces operational costs.
4. Availability and Customization
Vishay is now offering samples and production quantities of the 40 LHE sensor, with lead times estimated at 12 weeks. The device operates with a supply voltage of 5 VDC ± 10% and a typical supply current of less than 16 mA, with a recommended load resistance of 1 kΩ for both analog and PWM outputs. Additionally, a spring return option is available, and the sensor can be customized upon request to meet specific customer needs.
5. Conclusion
Vishay Intertechnology continues to demonstrate its commitment to innovation and excellence in the electronics sector with the introduction of the 40 LHE linear position sensor. By enhancing accuracy, durability, and usability, Vishay offers a powerful solution for a wide range of applications in harsh environments, reinforcing its position as a leader in the semiconductor and passive electronic component market.
As Vishay states, it is indeed “The DNA of tech.”
