Sensata Applied sciences has introduced the STEV sequence of high-voltage contactors for battery electrical autos and plug-in hybrid electrical autos, positioning the components as high-efficiency switches with “sturdy safety” for contemporary electrified automobile platforms. Sensata says the sequence targets OEM wants round security, effectivity, and integration in high-voltage energy architectures.
The contactors are high-voltage switches that open and shut {an electrical} circuit hundreds of occasions over a automobile’s life. In EVs contactors management energy move between the battery and methods such because the inverter and charger, making them a part of the automobile’s protecting structure and linked to security, effectivity, and reliability.

Sensata says the STEV sequence scales from plug-in hybrid passenger automobiles to battery electrical pickup vans and Class 8 heavy-duty vans. This scalability can assist OEMs standardize switching know-how throughout a number of automobile strains to simplify integration and scale back improvement time.
On design and qualification, Sensata says STEV contactors are customizable and based mostly on core switching know-how “refined over years of improvement.” The sequence is engineered to fulfill automotive security and high quality necessities, together with compliance with Superior Product High quality Planning (APQP) processes and different OEM certification necessities, for integration into international automobile platforms.
“We don’t simply manufacture parts. We engineer options with our clients, adapting our STEV contactors to the distinctive calls for of main OEM’s functions,” stated Markus Schwabe, EVP, Automotive and Aftermarket at Sensata Applied sciences.
The STEV sequence helps steady present carry scores from 150 A to 600 A and “excessive short-circuit stand up to functionality larger than 20 kA,” enabled by airtight sealing and modular designs.
Sensata additionally lists low contact resistance and minimized warmth technology, together with: single- or dual-assembly choices; bidirectional present functionality on choose fashions by way of non-polarity most important contacts; airtight ceramic sealing for arc containment and environmental safety (with IP67 ingress safety obtainable on particular variants); and electrical isolation specs together with coil-to-contact dielectric power as much as 3.0 kV and insulation resistance of 1000 MΩ at 1000 VDC.
Sensata provides high-voltage options via engineering and manufacturing websites throughout North America, Europe, and Asia to assist in-region manufacturing and localization.
