MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has announced the release of two new industrial-grade 1 Form A solid-state relays, the VO1401AEFTR and VOR1003M4T. Designed for demanding environments, these relays combine impressive load handling capabilities and fast switching speeds, delivering enhanced performance for industrial and other critical applications.
The VO1401AEFTR can handle a continuous load current of 550 mA with a load voltage of 60 V, while the VOR1003M4T offers a substantially higher current capability of 5 A and a load voltage of 30 V. Both devices are housed in a compact surface-mount SOP-4 package and feature an isolation voltage of 3750 VRMS, ensuring durability in harsh operating conditions. Additionally, with a typical leakage current of less than 1 µA, these relays promote energy efficiency by maintaining low power consumption.
These solid-state relays aim to replace traditional electromechanical relays, which are prone to vibration-related failures. Vishay’s optical relays offer vibration-proof, contactless switching, significantly improving reliability and service life. The devices’ robust design also supports applications in industrial automation systems, medical instruments, security systems, and broadcasting equipment, where high reliability and compactness are essential.
Fast switching capabilities further set these relays apart. The VO1401AEFTR has typical turn-on and turn-off times of 1.3 ms and 0.15 ms, while the VOR1003M4T achieves even faster times of 0.5 ms and 0.1 ms. This enhanced performance facilitates efficient operation in high-precision systems, meeting the demands of today’s advanced industrial control applications.
By combining high current capacity, robustness against vibration, and efficient design, Vishay’s new relays represent a significant advancement in solid-state relay technology. These innovations are poised to enhance system reliability and efficiency across a broad range of industries, reinforcing Vishay’s commitment to delivering cutting-edge solutions for evolving technical challenges.
