The Company
The manufacturer behind every component
SHR AUTOSENSOR TECH LIMITED is a true manufacturer — not a trading company. R&D, automated production and 100% final testing under one roof in Shanghai, powering OEM engineering teams in EV, semiconductor ATE, medical and industrial markets.
Every SHR AUTOSENSOR relay and contactor is manufactured under a controlled process and verified before it ships, so the datasheet numbers are the numbers you get.
Hermetically sealed contacts
100% hi-pot & parametric test
Full lot traceability
RoHS & REACH compliant
